Brd(Electroylic Gold finishing) got blisters

Electronics Forum | Sat Aug 27 09:47:05 EDT 2005 | davef

From the pic, we see blistering, but none so close to via that we'd attribute the blistering to via, via plugging, or anything of the sort. When we see blisters like this, we think of a surface contaminant being present on the boards at the time of

presently, the production facing this problem. We has couple of brd which is electroylic gold finishing with plug via. The brd has blister after the PCBA (in lead free temperature, 265 degree) Some time, bare brd already has the blisters. But most of

SIPLACE 3x8 mm shutterless S-feeder improves component supply

Industry News | 2009-01-30 18:39:51.0

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.

Adhesion and Puncture Strength of Polyurethane Coating Used to Mitigate Tin Whisker Growth

Technical Library | 2022-01-26 15:22:33.0

Reliability of conformal coatings used to mitigate tin whisker growth depends on their ability to contain tin whiskers. Two key material properties required to assess the reliability of a polyurethane coating are documented experimentally: adhesion strength and puncture strength. A modified blister test using a predefined blister area is employed to assess the adhesion strength and a puncture test is employed to evaluate the puncture strength of the coating. After measuring the properties at time zero, the coatings are subjected to accelerated testing conditions (high temperature/humidity storage and temperature cycling) and the degradations of the coating properties are documented.

Contamination Profile of Printed Circuit Board Assemblies in Relation to Soldering Types and Conformal Coating

Technical Library | 2017-12-11 22:31:06.0

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.
