Surface mounting technology – SMT A modern production process Modern module manufacturing is characterized by high functional and component density with growing demand for miniaturization and reduced surface requirements of the components on the PCB. At the same time, the focus is also on cost-optimized manufacturing. Over the last few years this has had a significant influence on the increasing integration of components and connectors that were previously conventionally assembled using wave soldering technology.

Basic principles Surface mounting – the basis for module manufacturing Surface mounting technology is the basis for modern module manufacturing and is the result of decades of optimization in the module manufacturing process. Module manufacturing can be optimized and transformed into a cost-effective, high-quality, and less error-prone production process by switching from wired components that are mostly assembled by hand to surface-mounted components that support automated assembly. 1. 2. 3. 4.

Fig. 1: Sequence for the surface mounting process In contrast to the through-hole assembly of wired components, SMD components have solderable connection surfaces that are soldered directly onto the top side of the PCB. In this process, the contact surfaces of the PCB are printed with solder paste, a mixture of solder particles and flux. The solder contacts on the SMD components are set into the paste and then soldered in the reflow oven (Fig. 1). A driving factor in the development of SMD components is miniaturization and the associated increase in contact density and functionality on the PCB. The focus was therefore on the optimization of components with an electronic function (resistors, diodes, or ICs). With the increasing availability of components, interface components such as connectors also came under the spotlight. Connectors with low current loads and low requirements in terms of mechanical strain are already used in SMDs. There are currently two ways of integrating connectors with high requirements in terms of current carrying capacity and mechanical functions: 1. The connectors are treated as standard components and wave soldered in a second process step 2. The connectors are integrated into the SMD process using THR technology 4 Phoenix Contact

Basic principles SMD and THR connectors for the reflow process The use of components for different soldering technologies often necessitates the provision of several systems (wave/reflow soldering system) and the PCB being assembled in stages. The concurrent use of SMD and THR PCB connection technology is aimed at reducing the number of production steps and manufacturing the module using just one soldering process. Adjustments to existing production equipment or to the process control system are to be avoided wherever possible here. Regardless of which mounting type is used – SMD or THR – the components must be developed for the individual process steps of SMT mounting and the respective requirements. Alongside the requirements on the components themselves, the components and the processing of these must be integrated into the process chain accordingly. The fundamental steps in the chain are: application of the solder paste via printing (Fig. 3), component assembly (Fig. 4), reflow soldering (Fig. 5), and finally inspection with a qualitative assessment of the soldering spots (Fig. 6). The aim of this integration is to be able to concurrently process wired through- hole THR components and surface- mountable SMT components – using the same equipment, in the same process, and under the same conditions. Only then is a reduction of the number of process steps (e.g., no additional wave soldering) and the more cost-effective manufacture of the modules achieved. 6 Phoenix Contact Fig. 3: Printing Fig. 4: Assembly Fig. 5: Reflow soldering Fig. 6: Inspection

Clearances on the bottom of the component The contact of solder paste on plastic parts and the undefined melting-on can lead to residual solder balls or solder bridges which, at worst, cause short circuits in the module. Where possible, the components should have large clearances (Fig. 10) around the solder pin or the surface contact and be equipped with spacers known as standoffs. Furthermore, it must also be ensured through the layout of contact pads (Fig. 11) or residual rings that there is no contact between the insulating body of the component and the solder paste. Colored SMD/THR components Components for the reflow soldering process should ideally be black – this ensures very clear demarcation between the contacts and the housing and facilitates image capture via camera systems for the assembly process. Colored components (Fig. 12) can only be made available if the thermal stability of their color pigments is sufficient and, for certain applications, if the pigments are UV stable (Fig. 13). The color palette available today is limited and dependent on the base material (polyamide or polymer). Thanks to improved exposure and contrast imaging, modern camera systems are capable of capturing the necessary details despite the poor contrast of the metals against the colored housings. , 5 0 8 4,05 0,55 4 , 4 2 0 , 6 6 2 Fig. 10: Example of documentation for the possible clearance below a THR connector M 2,5 6 6 , 4 3 , 6 5 , 1,4 2,3 Fig. 11: Example of a recommended layout for an SMD connector Fig. 12: Color versions 8 Phoenix Contact Fig. 13: SMD connectors in white for light connections are also UV-resistant

Hole diameter The use of THR technology requires modifications to the PCB layout. Selecting the correct hole diameter is important here. On the one hand, selecting a suitable hole diameter is important for ensuring the reflow of the solder in the reflow process; on the other hand, the hole size affects the ability to use automated assembly. Through the use of a suitable hole size, production tolerances are compensated and reliable assembly is possible. In practice, the longer the component the greater the production tolerances. To increase the assembly reliability of large, high-position components, it may be necessary to increase the internal diameter even further by up to 0.1 mm. For Phoenix Contact THR components, the recommended hole diameters for the individual series are documented based on the number of positions (e.g., see table for M12 THR connectors (Fig. 18)). Position tolerance – swash circumference The position tolerance of pins in through- hole pin strips indicates the permissible positional deviation of the pin tip from the zero position in the x or y direction. More illustrative is the swash circumference concept, which describes a circle with corresponding diameter for the deviation of the pin tip around the zero position. For example, in this case, a position tolerance of ±0.2 mm describes a circle with a diameter of 0.4 mm, the center of which is the ideal zero position of the pin tip. The current THR standard, DIN EN 61760-3, specifies ±0.2 mm as the maximum permissible position tolerance. This corresponds to a swash circumference with diameter 0.4 mm.

Mounting bosses Mounting bosses are plastic pins that are integrated into the housing of the component, positioned in holes without surface coating. They prevent the component twisting in the event of floating during the soldering process and therefore prevent an impermissible lateral offset to the layout. Whether mounting bosses are necessary or not depends on the weight of the component. As a general rule, the same position tolerances also apply to the mounting boss holes (Fig. 22). Armatures SMD armatures for connectors primarily have two functions. First, to increase the secure positioning on the PCB and the mechanical stability when the connector is being plugged in and unplugged. Second, the additional armature surface can generate the necessary additional adhesion for overhead soldering during assembly on both sides (Fig. 23). Fig. 22: Connectors with positioning pins (mounting bosses) Fig. 23: PCB terminal block with lateral SMD armature 4.4 Specific requirements on combination SMD/THR components Double function for THR armature pins In addition to the necessary mechanical stability, the THR armatures additionally perform the function of the mounting bosses and secure the connector against movement during the soldering process. In the area of the SMD contacts, the space on the secondary side of the PCB can be used for the layout. Fig. 24: Combination connector with SMD contacts and THR armature SMD contacts and THR armature metals Connectors solely intended for SMDs are used in device connection technology primarily within the device as board- to-board connections or wire-to-board connections, and less as direct external device connections. For external device connections and for end user operation, the same high mechanical load values are required as for those of wave-soldered or THR- soldered through-hole connections. These are difficult to achieve with a pure SMD connector with similar connector dimensions. The use of connectors with SMD contacts and THR armature metals is ideal in this case (Fig. 24). This type of connector must also satisfy the aforementioned requirements for SMD and THR connectors. At the same time, this combination provides clear advantages. 12 Phoenix Contact

5.2 Moisture sensitivity level for reflow components Along with the classification temperature, the moisture sensitivity level (MSL) is the parameter which precisely describes the treatment of the component during the reflow process. Levels 1 to 6 are assigned depending on the capacity of the component to absorb moisture (Fig. 26). 4 W 1 Y ∞ 168 72 48 24 TOL l e b a l e f i l r o o F l d e t i m i l n U r a e y 1 s k e e w 4 h 8 6 1 h 2 7 h 8 4 h 4 2 n o e m T i 1 2 2a 3 4 5 5a 6 Level Fig. 26: MSLs and their associated floor life 5.3 Maximum permissible floor life = safe processing without damage in the reflow process Exposed processing means the removal of the previously defined dry component from its air-tight packaging and the processing of this component within the time specified by the level. During this time, the component can absorb moisture without suffering damage in the reflow process. Components that can not absorb moisture or only little amounts are therefore candidates for level 1, “unlimited”, without additional dry packaging (dry bag). These can be stored in the open and have an unlimited floor life for the process. Components that absorb moisture are classified with floor lives from 1 year (level 2) down to just a few hours (level 3 – 6 ). These components need dry bag packaging. The floor life begins when the bag is opened and ends on expiry of the time specified by the level. The risk of component damage increases significantly upon expiry of the floor time (Fig. 27). In order to be used again, the components must be dried (re-baked) and returned to their initial state. 14 Phoenix Contact Opening of the bag Moisture absorption during assembly Increase of risk of delamination and cracks 0 = Start Floor life Stop @ e.g., 168 h Fig. 27*: Floor life, example of the process for MSL 3 components * From JEDEC [IPC-JEDEC J-STD-033D, Figure 3-3] ©Copyright JEDEC Reproduction with permission of JEDEC

5.5 Qualification profile vs. operator profile Even though the qualification profile is close to real-world conditions, there may be deviations from the real profiles of the operators. Ultimately, the suitable soldering profile depends on many factors. The process specialists need to find a compromise between board size and thickness, component types and density, solder paste and system equipment, and many other factors in order to solder the module cleanly. The qualification profiles and their classification temperatures therefore serve as a reference point for specialists as to whether the components can be soldered using the actual profile (Fig. 31/32).

Basic principles Process integration: PCB layout, printing, assembly, soldering, and inspection Optimum process integration begins with the PCB layout. It is at this early stage that the foundations for the best possible soldering results are laid. The correct paste application has a significant impact on the end result, but there are also corresponding conditions for the error-free positioning of components during assembly. The soldering process and subsequent inspection are well described in standards. Each process step places requirements on the components which they in turn must satisfy through the optimum selection of materials and product design. wider rings can have a positive effect on the soldering quality (meniscus formation). 6.1 PCB layout SMD layout The pad size for a certain solder contact size and the overall layout (arrangement and spacing of the pads) are usually recommended in the manufacturer’s proposed layout. The proposed layout takes a sufficient area into consideration to produce soldering spots in accordance with the desired class of IPC A-610. The arrangement of the contacts in relation to each other is largely influenced by the required air clearances and creepage distances. Tolerances that must be observed for the component and during assembly which affect lateral overhang and contact overlap influence the pad spreads. Connection surfaces oversized for safety reasons should also be avoided, as well as connection pads that are potentially too small and tend to have too much lateral overhang. Ultimately, the layout is a compromise which may be optimized at any time based on individual experience (Fig. 37). THR layout – pad design/residual ring With regard to dimensioning the residual ring, the same requirements as those for wave-soldered pads largely apply. Taking into consideration the air clearances and creepage distances and the clearance below the component around the pin, the ring width should be between 0.2 and 0.5 mm. The potentially larger volume of paste on M 2,5 6 6 , 4 3 , 6 5 , 1,4 2,3 Fig. 37: Example of a recommended layout for an SMD connector 18 Phoenix Contact

THR paste volume – base parameters The volume of the paste printing must be twice as large as the volume that the solder takes after melting. Approximately half (by volume) of the solder paste consists of solder aids such as activators and fluxes, the rest is made up of solder in particle form with a standard particle size of between 25 and 45 µm. Paste types are classed according to the particle diameter, among other things. The necessary volume must be generated through the appropriate design of the layout, optimized printer parameters, and based on the behavior of the solder paste. Ideally, there is no overprinting on the upper residual ring (less soiling) and a slight through-print on the secondary side of the PCB at 100% hole-fill (Fig. 42). The template cutout (Fig. 43) is designed with a diameter that is approximately 0.1 mm smaller so that the template lays on the residual ring (Fig. 44). This is intended to prevent the overprinting of solder paste on the solder resist. The necessary solder deposit results from the through-printed paste on the secondary side of the PCB. This method prevents soiling due to paste and reduces the risk of solder beading. 100 µm … 150 µm template thickness Solder paste with low tendency to drip No overprinting required (1) Targeted through-printing of solder paste with a through-printing of up to 0.5 mm below the PCB (2) 1 0 mm … 0.5 mm 2 Fig. 42: Base pressure (ideal) d s R di R dA dS = dA - 0.1 mm, where dA = di + 2 x R (dS = Template cutout Ø) (dA = Soldering pad Ø) (Ei = Hole Ø) (R = Residual ring width) Fig. 43: Recommended template cutout Solder paste Template Solder- resist PCB Residual ring Fig. 44: Template positioned on the residual ring – no overprinting THR paste volume – additional areas In certain applications, especially those where the solder paste is more likely to drip, the through-printing is reduced (Fig. 45). The missing paste volumes must therefore be generated elsewhere. A very simple way of reducing the through-printing is by adjusting the squeegee blade angle, or alternatively by adding bars to the template (see “THR paste volume – reduced pressure”, page 21). Less through-printing means a lower solder volume. To compensate for this, in certain spatial conditions, additional paste volumes can be made available through additional areas adjoining the residual ring. The melting paste flows out of these areas back to the residual ring and therefore increases the solder volume (Fig. 46). 100 µm … 150 µm template thickness Fig. 45: Reduced paste printing – less through-printing Fig. 46: Layout area for additional solder paste volume: layout and after printing 20 Phoenix Contact

Tape-on-reel packaging The most popular form of delivery for SMT assembly processes is tape-on-reel packaging (Fig. 52). Tape widths of between 16 mm and 104 mm are used for standard THR components. Due to the component size, tapes with very deep-drawn cavities are necessary – especially when dealing with tall components. A suitable feeder with a corresponding amount of free space must therefore be available. Furthermore, it must be ensured that the radius of the feeder is sufficient and that there is enough space for the tape to be fed into and out of the machine (Fig. 53). The space available at the feeder table of a machine is always tight (Fig. 54), especially if the feeder trolley is fixed and cannot be modified. This means that the use of the available space must always be optimized. Feeders in standard widths of between 16 mm and 56 mm are therefore preferred, 72 mm or 104 mm wide feeders are only installed in exceptional circumstances. This, however, also limits the component lengths/sizes in the tape. For larger components, both custom- made tapes and feeders are necessary. These are not unusual, but are uncommon and expensive. In such cases, it may be necessary to switch to the alternative – tray packing. Fig. 52: Tape-on-reel packaging Fig. 53: Equipped feeder Fig. 54: Limited space available at the feeder table Tray packaging in a flat magazine The alternative use of flat magazines depends on several factors. In terms of components, the external dimensions primarily determine the limits within which the use of tapes is still expedient. Components with large volumes in terms of length or height also fit in a tape, but the availability of suitable feeders, low packaging units per tape or dimensional limitations (deflection radius in the feeder) make their use in a tape system uneconomical. In this case, a flat magazine can be an economically attractive alternative (Fig. 55, Fig. 56). Often, however, when it comes to the equipment, it is the availability of a tray feeder unit (tray tower, Fig. 57) alone that determines whether it is possible to benefit from this advantage. Where a tray tower is not integrated, retrofitting is not expedient in most cases, as it is cheaper to have larger tapes custom made and purchase a wider feeder. The decision for an appropriate packaging option is therefore very dependent in each individual case on the existing assembly system and the components.

There is no one soldering profile that covers all components. The soldering profile is very individual and takes into consideration all of the process parameters – from the components, PCB, and solder paste to the equipment used (oven). It represents a compromise between all influencing factors with the aim of achieving optimum soldering results of a defined quality. The additional parameters and assignments in the above listed standard in terms of comparable component volumes, the component thickness and the maximum peak body temperatures enable a stress-reduced temperature load to conserve components that can not be subject to such high loads (see page 16 – Qualification profile vs. operator profile). 4. A qualifying test for components can be found in standard IPC/JEDEC J-STD-020 – Moisture/Reflow Sensitivity Classification for Nonhermetic Solid State Surface Mount Devices This standard is used by Phoenix Contact for THR and SMD connectors and their testing. The test cycle is described in “Qualification of components for the reflow process” (see page 13). Basically, this standard only describes the qualification conditions for the housing plastic, it does not qualify the soldering. The peculiarity of the qualification is the clear distinction between the maximum temperature loads on the side of the manufacturer and of the operator. A safety temperature buffer is specified here, which aims to avoid any overload by the operator. Recommended soldering profile Phoenix Contact qualifies reflow-solderable connectors and PCB terminal blocks in accordance with IPC/JEDEC J-STD 020. With information on the respective moisture sensitivity level and the classification temperature, the process specialists are able to closely estimate the processability of the components in the line with the individual profiles. In practice, soldering profiles based on IPC/JEDEC J-STD 020 are more conservative, so that soldering is performed at the lower limit of thermal loads. Standardization of the reflow soldering process The current standards relating to the reflow soldering process should be broken down into standards that describe the process and standards for the qualification of components. 1. A standard that mainly describes the requirements for SMD components and the soldering process itself is DIN EN 61760-1 – Surface mounting technology – Standard method for the specification of surface mounting components (SMDs) 2. This series of standards has been extended to include THR components in Part 3. DIN EN 61760-3 – Surface mounting technology: Standard method for the specification of components for Through Hole Reflow (THR) soldering – describes requirements on THR components and also on the soldering process itself 3. The process conditions described in DIN IEC 60068-2-58 – Test methods for solderability, resistance to dissolution of metallization and to soldering heat of surface mounting devices (SMD) – are used for qualification. The soldering profiles described in the application area of the standard can be used as the basis for the development of real soldering profiles 24 Phoenix Contact

With the optimum configuration of all parameters, the requirements for all criteria are 100% satisfied. In the micro-section, a fill level of at least 75% is achieved. A small solder cone forms on both sides (Fig. 67 – 69). side of the PCB and whose soldering spot can therefore not be assessed based on the usual aforementioned criteria of IPC-A-610. This is permissible if the pin lengths are reduced by the manufacturer and the component sits directly flush on the primary side of the PCB. Certain strategies for quality assessment need to be developed in this case. Micro- sections show here a reliable fill level and a good formation of the solder cone below the component (Fig. 70 – 72). Soldering spots with countersunk pin Where space is needed on the secondary side of the PCB, it is expedient to use countersunk pins in the layout. A countersunk pin is a pin that does not protrude out of the hole on the secondary Quality of THR soldering spots THR soldering spots have a shape that is very similar to that of soldering spots created during wave or selective soldering. The main difference is the shape of the solder cone.

Glossary Armatures Additional design element made of metal with a relatively large contact surface, usually mounted on the side of components. When soldered, it provides additional fixing for the SMD component and lessens the load on the current carrying contacts. Suction surface Planar, smooth (defined roughness) surface of sufficient size on the top of the component for picking up (with vacuum pipette) by the assembly system. Can be a direct part of the geometry or an additional component in the form of a pick-and-place pad or foil adhesive spot. Antistatic PE bag Electrostatically conductive polyethylene bag used as packaging for THR/SMD components. AOI Automated optical inspection Devices with camera systems that are able to inspect soldering spots. A comparison is made between the captured image of the soldering spot and reference images. Blister Synonym for tape, in this case more in connection with drawings for production documentation – blister drawing. Caution label Warning note on a label on outer packaging (mostly dry bags) regarding the handling of potentially moisture-sensitive materials. Vapor phase soldering Reflow soldering through heat transfer via vapor. Dry bag Outer packaging that significantly reduces the access of air to the contents and keeps the contents dry for a defined period of time. Feeder Feeder unit for tapes on pick-and-place machines. Floor life Exposure time Applies to dried, moisture-sensitive components. Upon opening the dry outer packaging (dry bag) the exposure time (floor life) begins, which depending on the MSL is a measure for problem-free processing in the 54 Phoenix Contact reflow oven. Once the floor life has expired, there is an increased danger of damage to the component. In order that it can be used again, the component must be re-dried. Gullwing Refers to a certain type of contact geometry on components. In particular the arched, angled component connections on ICs (integrated circuits) or also pin strips are named after the style of the winged doors on the legendary Mercedes-Benz 300 SL. Tape Tape-on-reel packaging Packaging material in taped format. The items are in individual cavities in a deep- drawn tape reel. The abbreviation for tape- on-reel is ToR. Inline system Layout of a production line in a physically connected line; all units (printer, assembly machine, reflow oven, AOI, and accessory components) are arranged one after the other in the process sequence. Advantage: transparent, replicable process. Disadvantage: the slowest device determines the process speed. IPC Association Connecting Electronics Industries – standardization organization based in Illinois, USA, involved in electronics production. JEDEC Solid State Technology Association – US organization involved in the standardization of semiconductors. Capillary effect In general, the behavior of fluid in contact with tubes or hollow shaped geometries. Here, the effect of the solder filling in and through the hole in which the pin is positioned from the bottom to the top side of the PCB. Classification temperature Working temperature for the component determined through testing in accordance with JEDEC J-STD-020. The manufacturer must test approximately 5°C above this temperature, the operator solders approximately 5°C below this temperature. This prevents any misunderstandings regarding the maximum load of the component. Contact pads Any type and form of metallic contact surface for the application of solder on the top side of the PCB (in contrast to the conductive path). Convection soldering Reflow soldering through heat transfer via hot gases (air or nitrogen). Coplanarity Coplanarity refers to the maximum distance of all connection contacts (including armatures) of an SMD component from the contact surface (in this case the PCB surface). It is a measure of whether all contacts have contact with the paste and are therefore able to form soldering spots at a defined paste thickness. Creepage distances Insulation coordination Minimum distance across the insulating medium between two live metal parts that must be maintained in order to prevent voltage flashover. Level goods Common designation for all components that in accordance with IPC-J-STD-020 have an MSL higher than 1 and must therefore be handled in a special way due to their moisture absorption capability. Soldering pad Normally a hole with a ring-shaped contact surface (residual ring/solder ring) surrounding the hole. The hole can be through-contacted. Solder meniscus/solder cone Geometric shape of the area of two metal surfaces/edges connected via solder (e.g., cone shape in the case of protruding stud contacts on PCBs). Mostly a concave, overrunning surface; with an increasing solder deposit, the radius decreases to a convex, bulbous accumulation in the event of a solder surplus. Solder paste Pasty mix of solder particles and flux for soldering components, predominantly in SMT. Solder pastes are classified according to the particle size. Solder beading When solder paste is applied, it is possible that non-metallic, coated (solder resist)
