Applying Thicker LPI Soldermask

Electronics Forum | Mon Jul 01 20:45:38 EDT 2002 | davef

Solder mask thickness specifications by fabricators are: * Wet mask: 0.0002 ~ 0.0004� on trace * LPI mask: 0.0002 ~ 0.0008� on trace Liquids usually range between 10 to 13 um (0.00039 to 0.00051") when dried. Liquid resist processes I have seen are

Dymax vs Humiseal Urethane Confomals.... Anyone?

Electronics Forum | Thu Feb 12 15:32:15 EST 2009 | gtemkin

A few other data points to consider. My experience working with Dymax 984LVF material was that its UV cure must be initiated immediately after coating, otherwise is surface will remain tacky forever, something like a post-it note tackiness, which wi
