New pcba supplier sent us first article pcbas (SMT, Wave & hand solder operations) that failed our testing due to no-clean flux residues found under ICs and around passive capacitors. Second lot came in and had 100% pass yield, but we still see a cl

Below are a few photos of an ongoing issue we are having with 1 pwb style. Some of the pads appear to have contamination that appears after the selective solder step. The joints are extremely hard to rework - almost impossible. We had the joints anal

A UP500 Wow! I did work on one last year. Most left out there are labeled QUAD AVX500's, then Speedline bought Sigmaprint and it became a UP500. But you get the MPM sigpro software with the Speedline machine; they didn't build to many. It was used

In general the chains don't need to be heated to 400 deg C for cleaning. In other words, most of the fluxes and constituents in the paste don't collect on the chain and gum it up. Bottom line: the heat treatment is not needed for 95% of the users.

Yeh due to the solvents in the coatings im guessing there is a health and safety risk. Solvent stripping is a lengthy process for the coatings we use and usually means submerging the whole board so not local to the rework. We have a booth with ioni

This is a late reply, but from my experience a really good removal station is one made by a company called CCRCo. They make a micro-abrasive station that addresses all the ESD concerns. They utilize a reusable media that is really cost effective. The
