Abstract
A handler (11) which transports a number of packaged semiconductor devices (12) in a boat (23) to a test head (14) and tests the devices (12) is provided. The handler (11) has an input staging section (29), a testing section (31) which is adjacent to the test head (14), and an output staging section (36). A boat transport (27a, 27b) moves the boat (23) from the input staging section (29) to the testing section (31) and from the testing section (31) to the output staging section (36). The boat transport (27a, 27b) operates during the device testing to provide substantially parallel operation of the testing and handling steps. A boat lift (39) moves the boat (23) to the test head (14) to allow the packaged semiconductor devices (12) to remain in the boat (23) during testing.
