Abstract

The invention relates to a production test fixture which belongs to the technical field of production test. In order to improve the test efficiency and lower the fixture cost, the production test fixture comprises a support plate, a perforated plate, a PCB and a plurality of testing pins, wherein the support plate is arranged below one end of the fixture for supporting a main board to be tested; the perforated plate is arranged under the support plate for fixing testing pins; the PCB (printed circuit board) is arranged below the perforated plate and is provided with a plurality of contacts; and the plurality of testing pins are respectively fixed in the perforated plate, one end of each testing pin keep contacts with a test point on the main board, and the other end keeps contact with the contact on the PCB during testing. By using the PCB as the substitute of testing box, the fixture can greatly reduce the product cost, and can further use the screen-printed wiring of the PCB as the substitute of the conductor wiring structure in the conventional process, thereby greatly simplifying the fixture structure, improving the testing efficiency, simplifying the testing process and shortening the entire production period.

Description

technical field [0001] The invention relates to the technical field of production testing, in particular to a fixture for production testing. Background technique [0002] The fixture currently used in the market is to fix the main board on the upper layer of the supporting board. The side of the main board with the test point faces downward, and the test box is directly below the supporting board. One end of the guide pin touches the test point on the main board, the other end connects the wire through the via hole on the top of the test box, and the other end of the wire connects to the test interface on the side of the test box, so that the signal of the main board test point is guided to the test box On the test interface on the side, the tester can perform the index test of each test point by connecting the test interface to the instrument. [0003] However, the above test method has the following problems: First, each test point on the main board needs to solder wires...
