Abstract:
1. A system to support testing of electronic devices, the system comprising: a loading device for loading the electronic devices onto a carrier board located at a loading site; a chamber having an inlet through which the carrier board is carried in and an outlet through which the carrier board is carried out, the chamber receiving the carrier board, which is carried in through the inlet after the loading of the electronic devices by the loading devices, and allowing the electronic devices, loaded on the carrier board, to be assimilated with a test temperature condition and then to be tested; an unloading device for sorting the electronic devices loaded on the carrier board, according to a grade, and unloading them from the carrier board, wherein the carrier board is located at an unloading site after being carried out from the chamber through the outlet; and a temperature control unit for supplying air to the chamber to equalize the electronic devices loaded on the carrier board located in the chamber with a test condition, wherein the temperature control unit comprises: a fan for supplying air to the inside of the chamber; a fan driving device for driving the fan; a fan housing for containing the fan therein, the fan housing having a suction hole for sucking air from the chamber and a discharging hole for discharging the air to the chamber; and an external air inflow controlling device for allowing external air to flow into the fan housing when the fan is driven or for blocking the external air.
