A burn-in sorter is provided to shorten an interval of process time by installing an additional DC(direct current) error head between a DC test part and a sorting part. A DC test part(110) performs a DC test. A transfer unit transfers the DC test part. A DC error/loading head(152) loads a circuit device to the DC test part, transferring in a first direction. An insert head(154) transfers a circuit device having passed a DC test from the DC test part to a burn-in board(104), transferring in a second direction crossing the first direction. The DC test part transfers in the second direction, approximating to the DC error/loading head in loading the circuit device to the DC test part and approximating to the insert head in transferring the circuit device to the burn-in board. A tray loader(120) can supply the circuit device to the DC test part. A tray unloader(122) collects good products, located in a position confronting the tray loader. A sorting part(130) receives products except the good products. The DC error/loading head transfers between the tray loader and the DC test part or the sorting part.
