Abstract
An electrical connection defect detection device to detect whether an electrical connection between an under-test pin of an under-test device and a signal line of a circuit board is normal is provided. The electrical connection defect detection device comprises a signal provider providing a test signal to the under-test pin through the signal line, a detection module and an electrode board comprising a detection surface and at least one array of through holes. The detection surface contacts a surface of the under-test device to make the detection module detect a capacitance value associated with the electrode board, the under-test pin and the signal line larger than a threshold value when their connection is normal. The through holes are placed along the edges of the electronic board and are electrically connected to a ground potential to perform a capacitive shielding.
