A semiconductor device test handler for maintaining stable temperature in a test environment may include a loading unit that loads a plurality of semiconductor devices mounted on a test tray; a soak chamber configured to receive the test tray from the loading unit and to age the semiconductor devices at an aging temperature; and a test chamber configured to receive and test the aged semiconductor devices. The test chamber may include: a test board; a first chamber; a second chamber; one or more pipelines connected to the first and second chambers that allow a temperature-control medium to flow between the first and second chambers; a de-soak chamber that further ages the tested semiconductor devices so that the tested semiconductor devices substantially return to ambient temperature; and a sorting and unloading unit that sorts the tested semiconductor devices according to results of the test and that unloads the sorted semiconductor devices.
摘要:
A forced air heat exhaust type of burn-in test apparatus for packages: A first air supply duct provides air to the burn-in chamber and a second air supply duct provides air to supply tubes that direst air into the test sockets that hold the packages. The test sockets have a structure that allows air ventilation of the conductive balls. Accordingly, the apparatus can control the temperature around the packages as well as the temperature in the burn-in chamber, thus preventing conductive ball-melting.

In one embodiment, a connector is made using a mixture of insulating silicone powder and conductive powder. The connector comprises a connector body formed from the insulating silicone powder and on or more preferably regularly arrayed conductive silicone members that are formed by migrating the conductive powder to a site of the connector corresponding to a solder ball of the semiconductor package. The conductive silicone member comprises a high-density conductive silicone part formed to be proximate an upper surface of the connector body and to protrude therefrom and a low-density conductive silicone part formed in substantial vertical alignment beneath the high-density conductive silicone part, the low-density conductive silicone part having a lower surface exposed from a lower surface of the connector body.
摘要:
A socket for testing a BGA package capable of avoiding problems like deformation of external terminals of the BGA package or failing to detect a defective BGA package and a test method using the socket are provided. The socket for testing a BGA package connects solder balls (or solder bumps) as external terminals of the BGA package via a mesh, a pressure conductive rubber (PCR) as a middle connection unit, and a channel connection means of a socket board. A plane board having POGO pins or a printed circuit pattern can be used for the channel connection means.
