Auxiliary fixture for making test support for high-density interconnection circuit board

Abstract

The invention relates to an auxiliary fixture for making a test support for a high-density interconnection circuit board. The fixture comprises a square tube and a copper bar, the upper parts of vertical beams on two ends of the square tube are respectively provided with an insulation block for clamping a hook of a gantry crown block, the bottom parts of the vertical beams on two ends of the square tube are respectively used for clamping two ends of the cooper bar, a plurality of clamps are evenly arranged on the copper bar, an upper cover which has the same shape as the upper part of the square tube is arranged on the square tube, and edges of two sides of the upper cover extend to the outer side of the square side. The auxiliary fixture has a simple structure and low cost, can well cover the square tube and the copper bar, ensures that the square tube and the copper bar is not directly polluted by drug liquid dropped from other circuit boards, and prolongs the service life of the square tube and the copper bar.

Description

technical field [0001] The invention belongs to the technical field of high-density interconnection circuit board processing, in particular to an auxiliary jig for making a high-density interconnection circuit board test base. Background technique [0002] In the production process of high-density interconnected circuit boards, it is necessary to conduct a circuit continuity test on the completed circuit board to determine the quality of the product. The test process is: firstly, make a bottom bracket with the same hole position as the circuit board Insert the probe into the hole, then gather and bind the lead-out wire of the probe, place the bottom bracket with the probe and the lead-out wire on the test equipment, put the circuit board on the bottom bracket, and connect the lead-out wire to the machine complete test. The bottom bracket needs to be made separately, and each bottom bracket only corresponds to one type of circuit board. The manufacturer needs to make a large...

AI Technical Summary

Problems solved by technology

The bottom bracket needs to be made separately, and each bottom bracket only corresponds to one type of circuit board. The manufacturer needs to make a large number of bottom brackets, and the hole position processing of the bottom bracket needs to be particularly accurate to ensure the accuracy of the circuit board test, so The operator must be very careful and conscientious, but since the bottom bracket is made on an ordinary workbench, the bottom bracket is placed flat on the workbench, and the operator needs to bow his head and bow his back to adapt to the position of the bottom bracket. Extremely unnatural posture can easily lead to fatigue. After a long time of operation, the cervical spine will be very tired, which will eventually lead to physical injury of the operator
