The auxiliary test connector for detecting good and bad integrated circuit boards clamps the integrated circuit board through the connection clamping device, and the guide rod is in direct contact with the integrated circuit board to play a connecting role. The external detection equipment can be detected by directly clamping on the guide rod. Because the guide rod is a conductor, it has almost no effect on the detection results such as resistance.
