High-precision aligned stitching testing machine

Abstract

The invention discloses a high-precision aligned stitching testing machine, and the machine comprises a supporting plate, a lower press unit, an FPC plate structure unit, an aligned camera unit, and a carrier unit. The supporting plate is provided with a group of openings, and the FPC plate structure unit passes through the openings to be disposed on the supporting plate. One side of the FPC plate structure unit is provided with the carrier unit, and the lower press unit is disposed beside the carrier unit. The aligned camera unit is disposed below the supporting plate. The machine is reasonable in structure, is convenient to use, carries out the amplification imaging of a tested object through the aligned camera, and can clearly check the alignment condition, so as to guarantee the accurate alignment, stitching and testing.

Description

technical field [0001] The invention relates to the field of testing equipment for electronic components, in particular to a high-precision alignment press-fit testing machine. Background technique [0002] Nowadays, electronic products are developing rapidly, and at the same time, the requirements for electronic components are getting higher and higher. The volume requirements of golden fingers and chip contacts are getting smaller and smaller, which brings great difficulties to the detection of components. [0003] The existing technology is a standard test method to check manufacturing defects and defective components by testing the electrical properties and electrical connections of online components, which includes open circuit, short circuit, capacitance, and resistance of flexible circuit board (FPC) products. , inductors and switches and other original testing. That is, combined with the error signal data generated by the test machine and the wiring data generated b...

AI Technical Summary

Problems solved by technology

When doing ICT testing on FPC, the traditional testing is manual testing. During the testing process, the pressure is not uniform and the pressure plate is not balanced, which will lead to inaccurate alignment between the test needle and the test point. The probability of test error is large, and the test speed is relatively slow, which seriously affects work efficiency

[0004] In addition, in the fierce competition in the consumer electronics industry, electronic components tend to be more and more lightweight, miniature, and high-precision testing is very difficult. For the tested product, the test point area is too small, how to carry out high-precision alignment pressing Testing, while reducing the test error, increasing the technical problems of speed and high work efficiency, need to be solved urgently
