Automatic Optical Inspection (AOI) is equipment that uses various light wavelengths or a laser to compare a finished layer to the original CAD data. Each layer that needs to be scanned will have an AOI file. Electrical test files are typically generated from a netlist that was provided by the customer with the original CAD data. Test machines at one time used test fixtures that were fabricated for each board design. These designs were typically referred to as bed of nails testing, were costly to fabricate and took considerable time and resources to maintain. One big advantage of this test method was that the test was very fast, just a few minutes depending on the number of test points. Today the trend is towards moving probe testers or flying probe (FP) testers. Flying probe testers are very versatile and require minimal set up time. The main drawback to the flying prob is testing time. Again, depending on the board density the test time could easily be 30 min per panel. Some flying probe testers test boards with a combination of resistive and capacitance measurements to help decrease testing time. In general, the flying probe testers have come a long way since their inception and are very common within the industry.
