Hi everyone,
We are currently trialing placement of some BGA's. The BGA's we are
placing are
0.8mm pitch. We have placed some on HASL boards with good results. There
seems to be a lot of talk regarding co-planarity problems using HASL. I
was
wondering if anyone uses HASL with BGA's and if so, do they get any
defects
related to the surface finish.
Thanks in advance
David
