| I'm very familiar with the great board space savings of BGA and all the "claims to fame." However, can someone out there tell me if any concern exist in the inspection realm. Additionally, solder cracking, CTE/TCE mismatches, no leads for stress re

| i am working on a no-clean process implementation project in a company. i want to change a board to no-clean which had dendrite problems underneath the small resistors on the bottom side(in smt).i want more information on the exact cause of dendrit

As an addendum to Daves posting, please consider that: There is no such thing as no residue fluxing. A no-clean must herefore, have benign residues - in other words, they are not as efficient at removing surface oxides to enable good solder joints. S
