摘要: A method for attaching two electronics boards, e.g., a testing PCB and a space transformer, comprises rack welding resin prepreg and a mylar film to a testing PCB; laser drilling via holes in the resin prepreg and mylar film such that the holes are aligned on one side of the resin prepreg with connection/capture pads on the testing PCB and aligned (after attachment) on the other side of the resin prepreg with connection capture pads on a space transformer, filling the via holes with sintering paste; applying a pressure treatment to remove air, bubbles, and voids from the sintering paste; removing the mylar film; and using a lamination press cycle to attach a space transformer to the resin prepreg.
