Q1.Does anyone know a way to verify the amount of OSP coating on a board? A1. There is no specification. Thickness is difficult to measure. Thickness is product related. There are at least six major suppliers. Years ago, here on SMTnet, J Medernach s

Responding to your questions ... RELIABILITY OF 1% SILVER SOLDER PASTE: It�s as good as the next solder paste, all other things the same. Look at your back articles by Jennie Hang in SMT magazine. I want to say she wrote an article on the topic i

Tough to say. It depends on the type of solder mask, the producer of the solder mask, and your board fabricators' process. As one angle on this, solder mask type affects thickness. Minimum clearance: * Liquid photoimageable: 2 thou * Screened liq

AVX and a few other companies make these chip transient voltage suppressors (TVS) parts that are a real *PAIN* to use. According to AVX: "Due to the semiconducting nature of the doped Zinc Oxide (ZnO) ceramic material, SMT TransGuards are no
