We see latches from some suppliers that just are not solderable. Usually the nickel plate on the latch is poor, allowing the nickel to corrode, and requiring a more active flux [if you're lucky]. But lots of times, you end-up with partial wetting,

Hi, There are "Fluxbuster" or "Rotator" pins on the market - we had to use them a few years ago on a flexy board (with OSP). There is some info from one source at the following link: http://www.isiconnectors.com/mfrs/idi/idipr.htm#Rotator We got

Hi all ! I have a very simple ( maybe stupid ) question : Can we mix the lead-free components with 'Pb components' ? I mean, some component would lead-free, but it is only 5% of the whole. Will I have problems on wave and on reflow ? Thanks for hel

I second that one Glenn. I have had really solid support from my paste company. Our guy is Kevin with Aimsolder. He is quick to respond and very knowledgable. We used a cheaper paste a while back, but never ever got any support. I wont make that mist
