my first thought was that too, but all the other components on tha board have reflowed properly. I have tow test boards, one with Imm Sn and other with Imm AG. on both these boards only the QFP has this solder phenemenon

Hi Dave, Why does it become " a bear" if u leave it unsoldered ?? Does it oxidise or something ?? Question (1): Does Ag imm. PCB need to use Solder paste with AG ?? If yes, why. Question (2): Does Ag imm pcb have poorer surface finishes than HAS
