I have two questions that maybe someone can answer? 1. Can or should lead free components be used with standard 63/37 processes? including sn/pb pcb's? 2. Can or should sn/pb components be used for lead free process? I have recieved mixed feeling

I currently have issues with "slivers" of solder on or behind QFP devices. This has only occured on PB Free boards (we currently produce PB and PB Free on same equipment). This is not tin slivers, this is a long thin sliver of solder measuring up to

yes you can use lead-free components and/or lead-free solder paste on Sn/Pb PCBs. You do get reliable joints. as already mentioned, it doesn't meet the WEEE and RoHS requirement. Indy

Anyone with definitive reliability data on mixing thru hole lead free terminations (SAC and Sn/Cu) with Sn/Pb solder. Seems like a lot of conflicting information

If you know "soldering Pb free (Sac based soler) to Pb/Sn coated lands is a no-no," why would soldering with Pb/Sn to Pb-free coated lands be different? If you are going to do this, follow the advice of an earlier poster who recommended higher peak s

I am Just starting to explore the Pb free soldering processes. It sounds like you have been involved for some time. I have a million questions, do you have contact info that I could use to discuss off line? Thanks

Kris, this practice has gone on for years. I have never heard of any problems associated with this. I have heard "grumblings" about tin lead parts being processed with lead free paste, but have seen or heard of no data to support. Russ

We are starting to see issues with using Kester WS R562 with lead free components. The joints look grainy on almost all of the 0402'2 and other small components. Some of the solder does not solder to the terminations. These are hybrid boards which

Hi Any body have any issues soldering tin lead solder paste with lead free terminations ? Components are leaded devices and chip components have read the theoritical discussions on the forum, need to know if any body has seen any real issues tod
