Patent ID: 7474531

Claim:
A circuit board testing jig, applicable for testing a circuit board, and dissipating heat generated by a heat-generating electronic element of the circuit board, comprising: a fixing frame, for supporting the circuit board; a platform, for supporting a heatsink module, wherein the heatsink module is used for dissipating heat; a displacement mechanism, comprising at least one slope guide section and at least one guide element, for enabling the platform to move between a ready position and an attached position, the slope guide section having a first end and a second end opposite to the first end, the guide element being disposed on the platform, the guide element sliding on the slope guide section and driving the platform to move accordingly; wherein when the guide element is positioned at the first end, the platform is located at the ready position, such that the heatsink module is separated from the heat-generating electronic element; and wherein when the guide element is positioned at the second end, the platform is located at the attached position, the heatsink module is attached to the heat-generating electronic element for dissipating heat.
