[0021] In order to make it easy to understand the technical means, creative features, achieved goals and effects of the present invention, the present invention is further described below.
[0022] like figure 1 As shown, a method for quickly extracting a circuit board netlist includes the following steps:
[0023] (1) Remove the coating: Use a sand blower to polish and remove the conformal paint on the surface of the circuit board; if a BGA packaged device is installed on the circuit board, the BGA packaged device needs to be removed and placed on the pad of the BGA packaged device. tinned;
[0024] (2) Determine the test point: fix the board under test on the guide rail of the test area of the flying probe online tester, and use the cameras fixed on the moving probe on the front and back of the flying probe online tester to take pictures of the actual circuit board under test. Obtain the front and back image information of the circuit board under test;
[0025] (3) Set ...
