Abstract
A socket for testing or burning-in electronic components has a cover including a heat sink and a sensor. The heat sink and sensor are spring loaded so they make direct, temporary contact to an electronic component in the socket during burn-in. A heat transferring device is coupled to each heat sink. The heat transferring device uses input from the sensor to provide heat or cooling to each heat sink to individually control the temperature of each component. The heat transferring device can be an electric heater or a cooling device, such as a fan. Both can also be used. A plurality of these sockets are used in a forced air convective oven for burning-in a plurality of electronic components at one time. The oven provides oven heating and cooling for all components while the socket heater and sensor provide individual temperature control for each component.
