A substrate manufacturing apparatus includes a test apparatus including a test handler module for performing a test process on a substrate. The test handler module may include a conveyor unit to transfer a substrate, a handler unit for performing a test process on the substrate, and a transfer unit for transferring the substrate between the conveyor unit and the handler unit. The conveyor unit may include a feed conveyor and a discharge conveyor spaced apart from the feed conveyor.

Apparatus and method for manufacturing substrates

A method of testing a semiconductor device using the test equipment includes loading an undivided printed circuit board (PCB) including unit PCBs in a test equipment. A semiconductor device is mounted in each of the unit PCBs. Product information of the undivided PCB loaded in the test equipment is confirmed. The undivided PCB whose product information has been confirmed is electrically connected to one of a plurality of main testers of the test equipment. Each of the main testers includes a main test interface directly connected to a cloud server in which firmwares for various kinds of tests are stored. The product information of the undivided PCB is transmitted to the main tester electrically connected to the undivided PCB. The main tester to which the product information has been transmitted performs a main test of the undivided PCB using the product information. The undivided PCB on which the main test has been performed by the main tester is unloaded from the test equipment.
