Abstract

The invention, which belongs to the temperature control field, provides a heat dissipation system of an integrated circuit tester and a control method thereof. According to the invention, a heat dissipation system of an integrated circuit tester uses a field programmable gate array (FPGA) master control chip as a core; a temperature sensing unit is utilized to carry out sensing on a temperature of a cabinet of the integrated circuit tester; and the FPGA master control chip is used to determine whether the sensed temperature is higher than a cabinet temperature obtained previously and a low frequency pulse width modulation signal output by the FPGA master control chip itself is adjusted. Therefore, control on a rotating speed of a cooling fan can be realized; an objective of reduction of power consumption and noises is achieved; and problems of large power loss and severe noise pollution are solved, wherein the problems exist in a heat dissipation system of a current integrated heat dissipation system.

Description

technical field [0001] The invention belongs to the field of temperature control, in particular to a cooling system and method for an integrated circuit tester. Background technique [0002] At present, the tester used in the integrated circuit production line, due to the continuous operation, the temperature of the tester case rises. When the temperature is too high, the components of the tester are prone to overheating failure or damage. Therefore, in the existing heat dissipation system, a cooling fan is provided outside the IC tester, and the purpose of cooling the IC tester is achieved by controlling the cooling fan to keep running at a certain speed. [0003] However, in the existing heat dissipation system, only the cooling fan is continuously operated at a constant speed to achieve the purpose of cooling the integrated circuit tester, and this heat dissipation method needs to be at the cost of extra power consumption. Because the temperature of the IC tester chassis...
