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
