Abstract: Polarity test of integrated circuit generally refers to the selection of a specific pin of the circuit for electrical performance measurement, rapid judgment of circuit placement whether reverse, dislocation, etc., the test method of Polarity test is the same as open short circuit test of IC. At present, polarity testing of IC mostly relies on the powerful and mature ATE implementation, but the cost performance of testing is not competitive. Based on the method of integrated circuit polarity testing, the paper produces an integrated circuit polarity testing "Micro Tester" with pure hardware to achieve the same capability of ATE, to communicate with the manipulator (Handler), and to achieve automatic testing, which is simple, stable, efficient and extremely low-cost.

Key words: polaritytest, openshorttest, microtester
