Abstract

In surface packaging of thin resin packages such as resin molded memory ICs or the like, cracks of the package occur frequently at a solder reflow step where thermal impact is applied to the package because the resin has absorbed moisture before packaging. To solve this problem, the devices are packaged moisture-tight at an assembly step of the resin molded devices where the resin is still dry, and are taken out from the bags immediately before the execution of surface packaging.
