Now I've checked the archives on this and found the starts of an answer but not much else, but then that posting was a while ago and I though there would be some more data now. So here's the question: who, if anyone is placeign Pb-free BGA's (ideally

I would agree if you have a board to setup the process. But sometimes this doesn't work... If for some reason if the customers AVL has a Lead Free BGA and I am running Leaded paste (yes this really happens!), you will need to run hotter to get your

The assumption that a HASL Sn63 PCB can be soldered with SAC solder paste is likely a bad one. The board itself is likely FR4 which can be damaged by lead free temperatures. The HASL finish isn't an issue from the perspective of it's makeup and actu

We switched our PCB's to 170Tg over 10 years ago, so we're probably good to go on the temperature aspect. Thanks for the opinion on the added lead content.

In switching to lead free processing, we find ourselves having over 400 PCB part numbers with Sn63 HASL finish. And there is no hope of quickly purging inventory and getting our drawings changed to call out a lead free finish. I want to avoid having

I set up some lead-free profiles on a new Heller1700xxx (Compact series), do not know if this is same model you refer to. Can be done, yes speed is a little slower than longer Heller Versions due to zones being so narrow, but doable. Of course all de

I was unaware of any Pb-Free process capable FR-1 laminate... not to mention capable of Though Hole plating that would be expected when wave soldering. What is the Td and Z-expansion for the laminate you are using?

Hello, I am facing intermittent delamiantion effect in FR1 type laminate after wavesoldring.Bath temp. is 255 degees cel.Preheater temp is also controlled (110 deg cel. on top side before passing on solder bath). Thanks,
