Having solder flow issues on gold pads. Issues started when supplier switched adhesive tape used to cover pads during varnish process. By running SEM/EDX and XPS analysis it has been determined that the new tape leaves behind a thicker organic residu

Josh: Room Temperature Vulcanizing (RTV) is Dow Corning's trade name for it's family of silicone cure sealants. RTV is about the worst kind of coating there is. Its chemistry is highly ionic and it requires atmospheric humidity absorbed to "complete
