Chip test device used for testing a chip packaged by ball grid array (BGA) technology

摘要

A chip test device is provided for using a printed circuit board to perform a test process. The printed circuit board includes a pin probe socket having a plurality of pin probe holes. A chip to be tested includes a plurality of protruding electrodes. The chip test device comprises a test base for electrically coupled to the chip to be tested, a plurality of elastic first pin probes, and a test converting board having a first layer with a plurality of pin probe holes coupled to a corresponding one of the protruding electrodes and a second layer with a plurality of second pin probes coupled to a corresponding one of pin probes on the printed circuit board.
