Common PCBA (printed circuit board assembly) plate test fixture

Abstract

The invention relates to the technical field of electronic industry and particularly relates to a common PCBA (printed circuit board assembly) plate test fixture. The PCBA plate test fixture comprises a fixture body, a partition plate and shaft sleeves embedded on left and right side walls of the fixture body, wherein the shaft sleeves are fixed on the fixture body by virtue of shaft sleeve pressing blocks; rotary shafts are embedded on the shaft sleeves; one end of a working cavity is fixedly equipped with adapter PCBA plate by virtue of two adapter PCBA plate fixing blocks; the adapter PCBA plate is connected to a to-be-tested PCBA plate; a carrier plate is arranged at the other end of the working cavity, a floating baffle block is arranged in the inner cavity of the carrier plate, one end of the floating baffle block is resisted against one end surface of the to-be-tested PCBA plate; the middle end of the rotary shaft is nested on the PCBA plate fixing blocks and the adapter PCBA plate. When the common PCBA plate test fixture is used, the manufacturing cost of the fixture is greatly saved, the mould changing time of the fixture is also greatly lowered, and the test efficiency is improved. The common PCBA plate test fixture has the advantages of a simple structure, reasonable setting, low manufacturing cost, and the like.

Description

technical field [0001] The invention relates to the technical field of the electronic industry, in particular to a common test fixture for PCBA boards. Background technique [0002] PCBA is the abbreviation of Printed Circuit Board + Assembly in English, that is, on the empty PCB board, it first goes through the SMT (surface mount technology) upper part, and then goes through the production process of the DIP (dual in-line packaging technology) plug-in. PCBA boards have been widely used since before the industrial age, and they are the core of computers and embedded systems. Since the production of PCBA is in the second half of electronic equipment manufacturing, it is regarded as the downstream industry of the electronics industry. Almost all electronic devices require the support of printed circuit boards, so printed circuit boards have the highest market share among electronic components in the world. At present, Japan, China, Taiwan, Western Europe and the United State...

AI Technical Summary

Problems solved by technology

[0003] The function of existing fixtures for testing PCBA boards is relatively simple. Usually, one PCBA board corresponds to one fixture. This undoubtedly requires a lot of fixtures, and it also costs a lot of money to make fixtures.

In addition, when encountering different fixtures for testing, it is necessary to continuously replace different fixtures, which requires more time for mold change
