Abstract:

The effects of an ultrasonic cleaning technique for removal of epoxy-type conformal coatings on printed wiring assemblies were investigated. The sample assemblies included 1 a standard comb-type printed wiring test pattern for evaluation of dielectric withstanding voltage, insulation resistance and Q, and 2 representative military type transistors mounted on printed wiring boards for evaluation of hFE and ICBO.
