Subject: [TN] Maximum HASL thickness for SMT of QFN

What is the maximum SnPb HASL thickness/uniformity that can be tolerated
in the SMT assembly of a .5mm pitch QFN package?  Is there anyone else
out there putting .5mm pitch parts on HASL finished boards that is
willing to share their experiences?
