Abstract
An opener for a test handler is provided. Even when holding members of inserts of a carrier board are manipulated to release semiconductor devices that have been in a held state, a predetermined distance can remain between an upper surface of the opening plate and a lower surface of the insert, thus preventing the inserts from becoming defective.
