█ Printed Circuit Board Assembly & PCB Design Forum

Program verification -- Hi all, Please explain me how the PICK & PLACE program verification can doing in your organization and what are procedures following. Thanks in advance

ENIG; Au < 0.5 um to avoid solder joint embrittlement -- We are designing a new PCB that will include a 0.4 mm WLCSP IC package. The OEMs application-note for this package states ENIG; Au < 0.5 um to avoid solder joint embrittlement. Our PCB fabricator specifies the ENIG Au thickness to be 0.04um, with a range of 0.05um to 0.125um typical. If the Au thickness is 0.125um on some PCBs, will this cause any placement/soldering/reliability issues for the 0.4 mm WLCSP? Thanks, Joe
