Does any body know how many US or europe based component manufacturers have decided not to use Sn/Bi on lead plating. Most of far east manufacturers seem to have selected Sn/Bi on their component finish. Intresting articles on Samsung,Epson and OKI w

Silver in paste is usually employed to prevent scavenging of silver from silver plated surfaces, BUT Dave's right. I wouldn't think Components are uniform enough to base a process change on. See how it goes with what you have. You will probably find

Bet your using tin/ lead plated components with a lead free Cu/Ag/Sn alloy. It leads to intermetallic cracking. Wow didn't anyone tell you to check the archives yet, It seems to be the answer given to everyone. Why have an interactive site if you alw

FYI: not all OSP are created equal. I have had expierence, both good and bad w/ OSP boards. To qualify the vendor I would take a bare board and run it thru my oven twice on a reflow profile then flux it with NC flux and run it thru the wave solder fo

Hi, I would like to know if someone is using a immersion AG for their board and if this plating modify the property of the solder paste? do I need to make changes on my temperature profile? We want to change from HASL to Immersion AG to mount

Hi mates, since I read about this immersion Ag plated PCB, was wondering if its so damm good, why so few people are using it? and why so long to market its PCBA application-virtues? feedback from bouncing this question around is Ag is prone to corr

We have had the crash protection installed on all of our machines and they are worth their weight in gold! Siemens installed some of ours on a special they were running last year, I believe it ran about $1,700.00 per machine, remember its a buyers m

Hi Ray, A couple of things to look into: 1.date code of reel 2. what is the termination made up of tin/lead or tin/lead/palladium. Check with part manufacturer. 3.paste volume/aperture openings 4.PCB plating 5.solder paste formulation Good luck R

We are starting to see a large increase in the use of through board gold plated connectors that require hand soldering with the limitation of .o6" encroachment up the pin. What is the best way to accomplish this? we currently scrap about 5-10% of t
