Hi, No Major issue using lead-free plated components in tin-lead as long as Sn/Bi is not the finish. I think some customer might be worried about low melting phase. More voiding may be seen in case of ceramic capacitors used with tin-lead. It is

Could you direct me to a Standard or Study that has used this termination with 67/37 tin/lead solder please? I am looking for the recommended reflow temperature requirements and reliability issues for the completed product. We are receiving this type

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

Hi everybody, I did post in the past last year and I always got good answers. If I'm going to solder something with Tin-Lead solder and then put it outside (it will be exposed to water, sun, cold nights,...), how long does it take starting to rust?

A simple answer is never. Tin lead will oxidize when exposed to oxygen, but it will not rust away like normal steel. I have old equipment from the 1920�s and 1930� that have solder joints as robust as the day they were made. Maybe not as shinny, b

I had a vendor change thier lead finish from tin/lead to a SAC305. We built up several assemblies before we realized the change. The reflow process is a standard leaded profile peaking at 220 C. What are the reliablity concerns with mixing the tin/l

I am trying to assess current industry thinking on the question of whether or not lead-free BGAs (SAC or other) can or should be soldered in a tin/lead process. It seems there are differing opinions on this and I'm wondering what some of you are doin

Anyone doing consigned work in the EMS industry has had this issue, I'm sure - Customer says they want lead free processing at the quote stage - PCBs they supply are tin/lead HASL. In this case, no HDI components and no BGAs. What is the latest acc

| We are wave soldering some fabs with a lot of unmasked trace area along the edges. The trace area is solid copper covered with tin / lead, no masking, no components along the edges, same on solder side and component side (goofy board design). Ins
