ABSTRACT:
A method and an apparatus for testing an internal circuit reduces working hours and production cost for an electronic product using a multi-fixture. A measuring pointer of a printed circuit board is decided with computer aided design data stored in the control part, and when the CAD data is not available, the measuring pointer of the printed circuit board can be programmed by sensing the pressure values for a printed circuit board with a pressure sensor. The amount of time spent when producing an electronic product using a multi-fixture is reduced and the productivity of the product by providing a product with a measuring section for measuring pointer for various models of the printed circuit board is improved. Further, the production cost of an electronic product is reduced because the test can be performed without manufacturing special fixtures. The space application is improved since the storing space of the special fixture is saved.
