Claim:
1. A method of testing a semiconductor device, the method comprising: loading in a test equipment at a loading part thereof an undivided printed circuit board (PCB) including a plurality of unit PCBs fixed on the undivided PCB with a semiconductor device being mounted in each of the unit PCBs, wherein the undivided PCB includes a pad portion including test terminals; confirming product information of the undivided PCB at the loading part of the test equipment including recognizing arrangement information of the unit PCBs stored in a code of the undivided PCB using a code recognition unit; conveying the undivided PCB from the loading part of the test equipment to a testing part of the test equipment; electrically connecting the undivided PCB whose product information has been confirmed to one of a plurality of main testers at the testing part of the test equipment by receiving the pad portion of the undivided PCB in a socket of the main tester, wherein 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; transmitting the product information of the undivided PCB to the main tester electrically connected to the undivided PCB; using the main tester, performing a main test of the undivided PCB using the transmitted product information; and unloading the undivided PCB on which the main test has been performed by the main tester from the test equipment, wherein electrically connecting the undivided PCB to one of the main testers comprises confirming usable main testers of the plurality of main testers, selecting one of the usable main testers, and electrically connecting the undivided PCB to the selected main tester, wherein electrically connecting the undivided PCB to the selected main tester comprises fixing the undivided PCB into a drawer of the test equipment electrically connected to the selected main tester using a test controller of the test equipment.
