Abstract: The substrate strip inspection apparatus is provided to easily replace the terminal of the test module by separating the test part and terminal part of the test module. The substrate strip inspection apparatus includes the test connection terminal(212) which is attached/detached to/or the connection terminal unit(12a) formed in the each substrate unit(12) of substrate strip; the test module(200) testing each substrate unit of the substrate strip; the support module(100) which transfers and supports the test module. The substrate strip inspection apparatus tests the electrical characteristic of each substrate unit of the substrate strip when the test connection terminal is connected to the connection terminal unit.
