Typical printed circuit board assemblies (PCBAs) processed by reflow, wave, or selective wave soldering were analysed for typical levels of process related residues, resulting from a specific or combination of soldering process. Typical solder flux residue distribution pattern, composition, and concentration are profiled and reported. Presence of localized flux residues were visualized using a commercial Residue RAT gel test and chemical structure was identified by FT-IR, while the concentration was measured using ion chromatography, and the electrical properties of the extracts were determined by measuring the leak current using a twin platinum electrode setup. Localized extraction of residue was carried out using a commercial C3 extraction system. Results clearly show that the amount and distribution of flux residues are a function of the soldering process, and the level can be reduced by an appropriate cleaning. Selective soldering process generates significantly higher levels of residues compared to the wave and reflow process. For conformal coated PCBAs, the contamination levels generated from the tested wave and selective soldering process are found to be enough to generate blisters under exposure to high humidity levels.

S-series tape feeders have been one of the most important components of many Siplace placement machines for many years. With its new 3x8 mm shutterless S-feeder, Siemens Electronics Assembly Systems (SEAS) now presents another improved version in the series. Fewer movable parts mean longer life and more reliability. The new feeder also handles a broader spectrum of components and makes the user's job easier. As a special benefit, owners of classic 3x8 mm feeders can have them upgraded to the shutterless version.

Over the years, humidity, moisture or extreme temperature fluctuations can adversely affect electronic assemblies. To ensure that PCB assemblies work faultlessly for a long time, certain areas can be given conformal coatings during production. At the electronica trade show in Munich from November 13-16, Viscom AG offers a comprehensive look at how easily the inspection of these coatings works with the S3088 CCI system.
