OK, you may be using this forum for your political rants - but if not, I will appease you one more time: Issue one at hand: Blame a political leader for my mistakes. I wish it were that easy. I'd blame Oprah for my top side wetting issues. Issue

This is one of the biggest mistakes with the Lead Free process. We have all listened to the 'industry experts' and followed their advice and unfortunately got it wrong. Keep the dwell times (dependant on alloy selection) the same as Leaded so you are

Good Morning, I have been struggling with this part for some time now. I have to agree that whoever designed this part, did not have to manufacture with it. We have advanced to a point where they have a acceptable yield but I believe that will be hi

Your customer is very unreasonable to demand void-free BGA SJs. Minor voiding is not a condition for rejection per IPC-A-610D, J-STD-001D, or even J-STD-001DS (Space addendum). Having said that, let me tell you that the voiding has little or nothing

Heck, now I look up and see this is SMTdotNET. Do I get banned for asking a TH question? So here's my first real TH issue after living so long in the SMT world. We are having a sudden issue in what has been a stable process for quite some time. I
