ABSTRACT:
Disclosed is a method and an apparatus capable of easily and quickly testing an automatic inserting state of an electronic component in a printed circuit board using a slit light. The method and the apparatus makes use of a slit light type instead of using the conventional testing jig in order to test an automatic insertion state of an electronic component in a printed circuit board. Thus, the problem of a noise generated when applying a signal which indicates that the contacting pins of the electronic component contacting with pins of a jig are testing incorrect, can be solved. Also, the setup time of an apparatus for testing an automatic insertion state of an electronic component in a printed circuit board according to changing a design of the printed circuit board can be reduced.
