Combine Automatic optical alignment system and the traditional flying needle machine together,
with the help of image-processing software and flying-pin-only cameras, flying probe test is easier and more accurate.
The electronic test for circuit boards is performed after manufactured. All the PCB manufactured by PCBWay must be checked with flying probe test.
The layout is analysed according to the PCB file for short circuits and interruptions.This is important because only the E-test detects incorrect and broken conductors. And the detected defective circuit board will be rejected or marked.
It is a common mistake that a once free of errors produced circuit board no longer needs to be tested by the E-test. However, because each production batch of a circuit board is a one-time process, the E-Test has to be conducted each time.
