  • Abstract
    When developing new MAPBGA package, package delamination was found after 96hrs autoclave test (121C, 100%RH, 15psig) through CSAM check and cross section analysis. MSL 3, 260C preconditioning was performed before the autoclave test. The improvement study was made on substrate power/ground gold ring design, substrate copper metal roughness and substrate metal layer design. Finally, the package delamination was completely removed by optimizing substrate design.
