Subject: [TN] Build backplane with lead free HASL surface finish?
Hello TechNet experts,
On our master fabrication drawing, the surface finish for backplane is
specified as ENIG, but the fabrication shop ask for waiver to build with
lead free HASL. Is it reliable enough? Any other concerns should be
taken
into consideration? Thanks a lot.
Best Regards
