Background technique

A jig is a tool of woodwork, ironwork, fitter, machinery, electric control, and other handicrafts. It is mainly used as a tool to assist in controlling position or movement (or both).

The classification of fixtures can be divided into three types: process assembly fixtures, project testing fixtures and circuit board testing fixtures. Among them, process assembly jigs include assembly jigs, welding jigs, disassembly jigs, dispensing jigs, irradiation jigs, adjustment jigs and shearing jigs; while project test jigs include life test jigs , Packaging testing fixtures, environmental testing fixtures, optical testing fixtures, shielding testing fixtures, sound insulation testing fixtures, etc.; circuit board testing fixtures mainly include ICT testing fixtures, FCT functional fixtures , SMT furnace fixture, BGA test fixture and CCD test fixture.

Many fixtures are produced because of commercial needs, because many types of fixtures are customized, and some are to increase productivity, repeat specific actions, or make work more precise. Because the design of the fixture is basically based on logic, similar fixtures may be produced separately because they are used at different times and places. The advantage of using jigs is that if the products are the same, even if the workers do not have very skilled skills, they can quickly produce a large number of good products with fewer defects and low variability through the jigs.
