Abstract
An opener and a buffer table for a test handler are disclosed. The opener includes an opening plate, a plurality of pin blocks forming pairs, and at least one or more interval retaining apparatus for retaining an interval between the pin blocks forming a pair. Each of the pin blocks is movably coupled to the opening plate, and includes opening pins for releasing a holding state of a holding apparatus that holds semiconductor devices in a carrier board. Although semiconductor devices to be tested are altered in size and a carrier board loading with the semiconductor devices is thus replaced, the opener does not need to be replaced, thereby reducing the replacement cost and the waste of resources.
