Any idea what the "industry standard" is for fall out on assembled PCB's? I realize that the controls put in place in your processes will effect your overall quality. But I'm trying for a general answer. On pre-tested assemblies, should you exp

I believe that gold fingers on my circuit boards are being contaminated and need to clean them with some chemical solution. Any recommendations. Chuck: What is the type and source of your contamination? Dave F We a

You'll not find any solvent, which removes cured epoxy and not attack the board material as well. If there are traces underneath the surface mount components even mechanical removal of the epoxy may mess up your boards. As a mechanical tool I recomme

I'm very familiar with the great board space savings of BGA and all the "claims to fame." However, can someone out there tell me if any concern exist in the inspection realm. Additionally, solder cracking, CTE/TCE mismatches, no leads for stress re

Require a conductive adhesive - either isotropic or anisotrpic - which can be used for 100micron oitch devices. Must be resistant to solvents such as MEK and acetone. Cure below 150C, with possible potential for rework of the conections.

Yo! Who's got a decent used Airvac/Solder fountain for sale?

Hey there ya'll!! I went and looked at the used equipment page here, and I've also looked around at a few other sites to try and find me a used PTH dynamic solder pot...like a Airvac type of unit. It doesn't have to be as fancy as a Airvac, just
