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.

Specialty Coating Systems is pleased to introduce the new SCS Precisioncoat Tool Changer – a flexible, advanced coating feature on SCS’ Precisioncoat V platform. The Precisioncoat Tool Changer is a robust, motor-driven 5-axis system capable of selecting and hanging up to five valves and/or tools within a single program profile. Each valve and/or tool enjoys programmable 0-360° rotation and ± 0-45° tilt. Because multiple heads are combined into one system, the SCS Precisioncoat boasts a full 22.5" (571 mm) x 21" (533 mm) work area on every valve. The SCS Precisioncoat also has the largest pass-through height available, measuring 5" on top and bottom.
