Abstract

The invention relates to a portable automatic test fixture, comprising a tooling, a PCB connecting board, a plurality of digital-to-analogue converting modules, an analogue interface module and a controlling module, wherein the tooling is fixed with the PCB connecting board; the digital-to-analogue converting module are arranged separately with the PCB connecting board; and the controlling module comprises test programs. The implementation of the tooling of the sequential logic module in the invention can realize automatic detection, simplify test procedures, improve production efficiency and avoid artificial carelessness on the one hand, and on the other hand, testing is carried out without needing to assemble the sequential logic module into a semi-finished product, thus reducing defective percentage and lowering rejection rate.

Description

technical field [0001] The invention relates to a test device, more specifically, to a portable automatic test tool. Background technique [0002] At present, integrated control chips do not have corresponding testing equipment after they are designed. For example, sequential logic modules refer to control circuits involving single-chip microcomputers, DSPs, FPGAs, etc. that can be programmed using timing. Such sequential logic modules include digitally controlled fluorescent lamp rectifiers, communication modules, etc. Due to the complexity of the sequential logic modules and the randomness of program logic, it is difficult to test them in the production process through a simple method. [0003] The usual practice is: 1. After production, the sequential logic module is assembled with other modules into a semi-finished product, and then the semi-finished product is tested uniformly; 2. The tester makes the tooling and performs manual testing one by one according to the funct...
