We: * Cure 1B73 according to spec in a heat box, like a Blue-M * Clean nozzles [one set in use, one set being cleaned] in thinner in a bronson ultrasonic cleaner * Haven't evaluated coatings in years, but would do it according to J-STD-001C, Reqmnts

Re: item 3 - there are ultrasonic thickness machines (Panametrics makes one) that can measure coating dry with a small transducer head. A little pricey for ones that measure reliably in the .003" +/- .002" range.

We have experienced poor adhesion of acrylic conformal coating to plastic bodied IC�s. The observed symptoms of this are a blistering or lifting of the coating at the surface of the component, although peel testing has revealed that this is not alwa
