Hello, I am currently trying to isolate internal fallout problems with very low yield substrates mixed with great yields and have recently found that we are using a Sn62/Pb36/Ag2 solder paste with full tin (no lead) components as well as Pb95/Sn5 sol

I assume you are talking about Sn62Pb36Ag2 solder. You should not see any added concerns when subjecting Sn62 to multiple reflow cycles as compared to Sn63. As compared to Sn63Pb37: Reduced leaching issues Increased Wetting due to lo

Hi Chris Good Day!!!! well we are running flex panel(150x270) with one connector(3 pin legs both sides) insert. Each panel consists of 28 parts and its used for disk drive industries. We are having a pallet to support with the top cover design such

Im trying to get the XY data to program the SMT machines. since i dont have the file, im trying to convert it from the gerber drawing. the closest one to represent the component placement is the solder pad. ive tried using linkcad to convert it to XY

we do that and there's a variation on the solder temp. sometimes around 10 degrees, we have 2 solder pallets that are run in intervals of roughly 3 1/2 minutes a part (the time that take the operator to put all 3 terminals in a 42 pcbs per board, and

I've got good news and bad news: GOOD: I love Ag2 solder it's the best, most well behaved, reliable, couldn't ask for a better general purpose solder. BAD: It's leaded. I'd be concerned about embrittlement issues when soldering to gold that was 10 t

I could not see pictures of your board - please attach one or two. So to answer your questions: 1. wave should not overflow over your board - mostly we use pallets as carriers to protect the assembly. 2. Solder dross is caused because your wave is no

| We process both tin/lead plated boards and gold plated boards in our surface mount group. I have used Sn62/Pb36/Ag2 solder paste on all gold plated boards to help prevent gold scavaging. To reduce the amount of different solder pastes we have to
