Hi Happy,
I can't help you with the lead free HASL but be careful with acronyms. A lot
of people use the acronym PCB for assemblies and PWB for printed wire board.
I'll bet your customer is really requesting totally lead free assemblies.
Just my thoughts,
KennyB

Subject: [TN] Lead-free HASL
We have a customer asking for Pb-free HASL. I am not familiar with this
finish. The temperature for Pb-free solder would be quite high and the
effects on a board, as well as the HASL equipment might be detrimental. The
customer says it is used in Japan, he quotes a Matsushita Electric news
release. The release seems to indicate that they are using a lead-free
solder paste but that word is not used, just "PCBs with lead-free solder".
Does anyone know of a Pb-free HASL process?
Happy Holden
