Here's what I do: - Test Surface Insulation Resistance (we're in the high reliability market and use a test significantly harder than IPC's). I also test SIR in combination with other assembly materials like conformal coatings and wave solder flux

Josh, are you setting someone up with these questions? Answers to your questions related to the subject line follow: Q1. Does the Epoxy Solder Mask Layer of a PCB protect against moisture absorption? Is this a primary function of the solder mask?

Jason: Wave soldering is the coolest thing!!!! First, so, what�s the chemical analysis of this white res? Can you point us to either tin, rosin, or something else? Second, how do you know that you are making these white residues? Could your boar

John- Just few ideas at random (brainstorming) - While times are slow invest in training of your current staff. There are some great training facilities out there offering valuable knowledge. Knowledge is a valuable thing to have and will prove to be

Hey Jack: It's certainly "do-able." Conformal coating adhesion testing was done as part of the "Evaluation of Low Residue Soldering for Military and Commercial Applications: A Report from the Low Residue Soldering Task Force," published by Sandia Na

| | | Has anyone out there tried to parylene coat plastic parts prior to soldering them to a pcb? I'm looking at several potential applications where fewer than 5% of my components on a pcb are plastic, yet from a reliability aspect (environmental co

| Has there anyone bold enough to try this in their shops? My cubemate just got through telling me that at his last shop, they had bare copper boards (no HASL, no OSP, no nothing), with minimal solderability problems. | yes, 8 years ago I developed
