Hi, What would you consider significantly different about lead-free on flex circuits than tin-lead of flex circuits ? Have you published your experiances that you encountered while changing over to lead-free solder paste from a tin-lead paste ? T

We have carriers that we use in wave flow solderers that are machined specifically for each board out of ESD composite. I was wondering if anyone knows about lead contamination of this material and the cleaning of composite? I know that it is a p

I have been seeing this with a new BGA we have just started using from IBM. Is this a problem if the solder paste is wetted to the unreflowed BGA balls??? It passed our ESS testing with no problems.... TIA JD

Barbara, I worked for 5 years with advanced materials including silver filled thermoplastics and epoxies for Alphametals. There is a trend towards lead free "solder paste". Some companies are using an Indium alloy paste and others are using a "lea

Lead free is not define as NO lead and "a maximum concentration value of 0.1% by weight in homogeneous materials for lead shall be tolerated." Check below link. So replaced your solder from the pot when exceed 0.1%. http://www.leadfree.org/files

Search the fine SMTnet Archives for background discussion on BGA voids.

Hi, There are many companies shifting lead free solder wave. My question is can anyone give me idea if we can still use our old solder wave machine for lead free eventhough the solder pot is stainless steel 316L? Our solder bath has titanium nozzl

Your friendly wave guy here, check out Aim solders web site. click to the right where it says lead free. There is a complete discussion on what can occur. http://www.aimsolder.com
