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.
