Via Bond attachment
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.
Probe apparatus
The present invention provides a probe apparatus, which comprises a signal transmission device, a probe, and a bottom fixing device. The signal transmission device includes a first transmission part and a second transmission part. An end of the probe is connected electrically below the second transmission part. The bottom fixing device is disposed below the signal transmission device. An end of the bottom fixing device includes a first penetrating hole and a first recess is disposed below the end. The probe passes through the first penetrating hole of the bottom fixing device. The probe is located in the first recess. The bottom fixing device reinforces the mechanical strength of the signal transmission device so that the width of the signal transmission device can be reduced. Thereby, the benefit of high-density arrangement of the probe apparatus can be achieved.
