Abstract

The invention provides a printed circuit board assembly (PCBA) board testing system. The PCBA board testing system comprises a control end and a testing tool. The testing tool comprises a testing unit, a burn unit and a connecting circuit, wherein the connecting circuit is connected with a testing pin and a burn pin of a PCBA board. The control end comprises a burn control unit and a testing control unit, the burn control unit is used for controlling the burn unit to carry out program burn on a programmable chip on the PCBA board. The testing control unit is used for controlling the testing unit to carry out testing on each function circuit of the PCBA board, calling the burn control unit to carry out burn control, and carrying out testing on the burnt programmable chip and a chip control circuit of the PCBA board. The invention further provides a PCBA board testing method. According to the PCBA board testing system and the PCBA board testing method, due to the fact that a burn program is inlaid into an automatic testing process, a function circuit testing process and a burn process are simultaneously carried out, not only is the testing tool saved, but also efficiency is improved.

Description

technical field [0001] The invention relates to the field of chip programming and testing, and more specifically, to a PCBA board testing system and method. Background technique [0002] With the rapid development of electronic industry automation, a large number of various programmable chips were born. Thus, various IC programming (burning) devices have been produced. [0003] The existing burning method is as follows: manually place the programmable chip to be burned on the program burner, and burn the program into the programmable chip; Go to the PCBA board and then conduct the overall test of the PCBA board. [0004] However, the use of the above-mentioned burning equipment is too single, and the cost is high; and the method of using the burning software to burn through the burner is complicated to operate, and operation errors are prone to occur during the burning process, resulting in an increase in the defective rate of the product; in addition, The above-mentioned...
