A Conversation about Solder Paste Inspection with Christopher Frederickson
Today, we’ll be discussing Fit for Use solder paste inspection. As I’ve repeated several times on this show, it is said most reliability problems begin at the printer. Our industry utilizes a lot of materials in order to produce a circuit assembly. If the materials, specifically the solder paste is out of spec, that can effect reliability. Unfortunately, in most cases, one can not simply open a jar of solder paste and easily determine visually if the solder paste their applying to the stencil is fit for use, or if it has gone bad, or is out of spec.
My guest today will discuss what solder paste fit for use means, and how we can provide methods for determining its fit for use right on the production floor. My guest also, on a completely unrelated topic, but maybe even more interesting, has experience in wearable electronics in temporary tattoos. You subject that’s the first question I’m going to ask him about!
