Classification and uses of treatment tools

In the production process of SMT patch processing factory, some jigs are often used. Let me briefly talk about the classification and use of jigs:

Classification of fixtures: Fixtures can be divided into three categories: 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;

Project test fixtures include life test fixtures, packaging test fixtures, environmental test fixtures, optical test fixtures, shielding test fixtures, sound insulation test fixtures, etc.;

Circuit board test fixtures mainly include ICT test fixtures, FCT functional fixtures, SMT passing fixtures, BGA test fixtures, etc.

Purpose of jigs: Jigs are produced due to commercial needs, including mechanical jigs, woodworking jigs, welding jigs, jewelry jigs, and other fields. Certain types of jigs are also called "molds" or "auxiliary tools" and their primary purpose is to reproduce a certain part reproducibly and accurately. Many types of jigs are customized, some to increase productivity or to make work more precise.
