| Does anyone know if I will have problems soldering surface mount components to an all hard gold plated PC board. We want to use hard gold similar to gold used for edge fingers because our customer is concerned about wear and conductivity of connect

Mr. Wizard is not currently available. You get the wizzer. Maybe your dream date will show later. Get your own lab tests done. Show your potential customer that your boards are clean. That�s the issue. The issue is not how you go about cleaning

Dave F asked me for an update on the SRS we evaluated last month... I like this machine. Over 80% of your wave dross is actually good solder; you just can't get to it without some type of separating agent. I like the mechanical sepration method mu

I agree but, are there really heavy metals in this water? Our process is as follows. Print Paste Reflow Board (no components, water soluble paste only) Wash Board Same reflow profile for almost every order so no solder balling issues etc. Carbon an

Dear adam Sounds to me like it may not be Salt water contamination or even flux residue's, as both of these are commonly cleaned semi aqueosly or with IPA. Have you considered it may be Talcum powder used as fillers in solder resist, mineral salts

Hey guys, Anybody having trouble with increased false contact issues in ICT after switching from lead to lead free? Our test guys keep trying to imply that the flux residues are a problem (we're using Alpha EF2202), but as the soldering process eng
