Abstract
The utility model discloses a device for testing a printed circuit board. The device comprises a box and an upper cover of the test device, and an externally connected power supply. The box is provided with a test circuit board used to detect the printed circuit board. A left plug board and a right plug board of the test circuit board are disposed on a left side and a right side of the box. The left plug board and the right plug board are provided with interfaces connected with circuit terminal studs of the test circuit board. LED lamps and a current-limiting resistor communicated with a printed circuit are disposed on the test circuit board. The LED lamps of a connected circuit expose from holes which are disposed on the upper cover. Wiring plugs on two ends of a to-be-tested printed circuit board are inserted into the interfaces on the printed circuit board test device, and the printed circuit board is detected through a test circuit set in the test circuit board of the test device. Quality of the printed circuit board can be directly determined through whether or not the LED lamps exposed through the upper cover are lightened. The device not only improves test efficiency and accuracy, shortens time, but also improves detection operating conditions.
