  • Publication number: 20200088764
    Abstract: A probe card testing device includes a testing circuit board, a signal transmission board, an electrical connecting module, and a probe head. The testing circuit board has metal pads spaced apart from each other. The signal transmission board has internal pads arranged on a bottom surface thereof and spaced apart from each other. The electrical connecting module includes a spacer having thru-holes and elastic arms positioned on the spacer. The spacer is sandwiched between the testing circuit board and the signal transmission board. The metal pads respectively face the internal pads through the thru-holes. A part of each elastic arm is arranged in one of the thru-holes, and is detachably compressed by one of the metal pads and the corresponding internal pad so as to be elastically deformed to establish an electrical transmission path. The probe head is disposed on a top surface of the signal transmission board.

The multilayer interposer with high bonding strength comprises a plurality of thin-film layer structures overlapping sequentially. One of the thin-film layer structures comprises at least one first conductive blind via. An interconnection layer electrically connected to the first conductive blind via is configured on the surface of the one of the thin-film layer structures, and the interconnection layer comprises at least one head portion. Another one of the thin-film layer structures comprises at least one second conductive blind via. The bottom of the second conductive blind via contacts both of the corresponding head portion and part of the surface of the one of the thin-film layer structures. Thereby, the bonding strength between layers can be dramatically increased, and the resistance to the thermal shock can be also increased.
