An ACI Technologies customer inquired regarding printed circuit board(PCB) failures that were becoming increasingly prevalent after the SMT (surface mount technology) manufacturing process. The failures were detected by electrical testing, but were undetermined as to the location and specific devices causing the failures. The failures were suspected to be caused predominately in the BGA (ball grid array) devices located on specific sites on this 16 layer construction. Information that was provided on the nature of the failures (i.e., opens or shorts) included high resistance shorts that were occurring in those specified areas. The surface finish was a eutectic HASL (hot air solder leveling) and the solder paste used was a water soluble Sn/Pb(tin/lead).

In order to keep up with industry demand, IPC has released amendments for J-STD-001F, Requirements for Soldered Electrical and Electronic Assemblies, and IPC-A-610F, Acceptability of Electronic Assemblies. For each standard, IPC-A-610F Amendment 1 and IPC J-STD-001F Amendment 1 represents a critical shift to deliver necessary updates to these already robust standards.

More than 350 engineers who attended last week’s IPC webinar, Soldering and Assembly Defects, were polled on their biggest headaches with printed boards, PCB components and PCB assembly process failures. The survey results which identify solder finish, ball grid array (BGA) components and reflow soldering as the greatest challenges, provide webinar co-sponsor, National Physical Laboratory (NPL) of the United Kingdom with useful information as it prepares its NPL Process Defect Clinic for IPC APEX EXPO® 2012.
