Abstract

The invention provides a circuit board detection system. The electrodes of a region to be bound of a circuit board to be tested are immersed in a test solution and are conducted by using a conductive property of the test solution. Test voltage is sent to the control unit of the circuit board to be tested to detect the impedance between the two adjacent electrodes in the region to be bound of the circuit board to be tested. According to the impedance detection value between the two adjacent electrodes in the region to be bound of the circuit board to be tested and the conductivity of the test solution, whether the circuit board to be tested is qualified is determined. On the one hand, the quality of the circuit board to be tested can be detected without a need to match a dedicated test circuit board to the circuit board to be tested anymore, thereby reducing the testing cost of circuit board. On the other hand, the conduction of the electrodes can be guaranteed as long as the electrodes of the region to be bound of the circuit board to be tested are immersed in the test solution, the electrodes are not required to correspond to one another one by one, thereby improving detection efficiency.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a circuit board detection system. Background technique [0002] With the widespread use of the SMT (Surface Mount Technology, surface mount technology) process, the quality inspection of circuit board products produced according to the process has become a crucial issue. [0003] The circuit board includes: FPCA (Flexible Printed Circuit Assembly, finished product of flexible circuit board) and PCBA (Printed Circuit Board+Assembly, finished product of printed circuit board). Test circuit board matching dedicated test circuit board) to achieve. During quality inspection, the electrodes in the area to be bound on the test circuit board need to be aligned with the electrodes in the area to be bound on the circuit board to be tested. Therefore, the detection efficiency is low and becomes a bottleneck in quality inspection. Moreover, corresponding dedicated test circuit boards need...
