Always wear appropriate. A PCB cross sectional test, also known as microsection analysis, is a process used to analyze the internal quality of a printed circuit board. It is a board that has lines and pads that connect various points together. Reports generated automatically with each test and provide a good reference of the results, and the modularity within the code provides great flexibility to integrate new PCB products with no change in code. Before PCB design, circuit designers are recommended to get a tour of a PC board shop and communicate with fabricators face to face over their PCB manufacturing. Drewniak, Amendra Koul, Fan Zhou EMC Laboratory, Missouri University of Science & Technology Rolla, MO 65401. The test measures results as bulk ions per square inch. In circuit testing (ICT) is traditionally used on mature products, especially in subcontract manufacturing. Bear in mind that a flying-probe e-test rarely checks for shorts as it requires a huge amount more checks (therefore test time) than a continuity test - each node to each other possible node. This field test kit has become the standard in testing for PCBs in insulating fluid. Adding a Huntron Access Prober to your test procedure will significantly decrease test times therefore increasing productivity.
