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
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
