Since I'm new to the forum I probably ask previously answered questions (that I have not found) but I would be grateful if someone could clarify this for me. I'm in R&D at a company where we design low volume (1k-10k) fairly complex PCBAs for our pr

Hi all, Does anybody have any comments on the lead-free alloy SN100C from AIM solder? I am in the process of selecting the "right alloy" for our lead-free wave solder machine. We manufacture A/V equipment. I appreciate your feedback as usual. Hir

I said: "Our electronic circuit board fabricators seal the boards in moisture barrier bags [MBB]. We discontinued the use of desiccant bags in these MBB because of concerns about the desiccant releasing materials that would affect the solderability

We are looking at reflow soldering some Flexi-rigid pcbs. I have heard that IR reflow soldering can make the Polyimide "self heat" and cause de-lamination. Does anyone have any info.

A number of years ago I used a Kester product called Solder Saver. It is a thick liquid that one squirts onto the dross on a hot solder pot. It separates out the solder leaving a crust of almost clean dross. Unfortunately a mask is still required. Th
