Abstract
The utility model discloses a tool for detecting an open circuit and a short circuit of a flexible circuit board. The tool comprises a detection main board and a needle plate. The needle plate is provided with a probe at a position corresponding to a test point on a to-be-tested circuit board, and the probe can be electrically connected with the corresponding test point. The tool also comprises an LED lamp and a conductive cloth. The conductive cloth is contacted with a ground steel disc on the to-be-tested circuit board to form electric connection. The conductive cloth is electrically connected with one wire pin of the LED lamp, and the other wire pin of the LED lamp is electrically connected with the detection main board. The tool is advantaged in that conductivity of built-in wires and the ground steel disc of the to-be-tested circuit board can be detected while detecting an open circuit and a short circuit of the to-be-tested circuit board, and work efficiency is improved with the adoption of the tool.
