Semiconductor chip high and low temperature testing machine failure causes explained

As we all know, the semiconductor chip high and low temperature testing machine is a component of the semiconductor industry to use more test equipment, its failure is also a clichéd problem,semiconductor testing so what are the semiconductor chip high and low temperature testing machine failure? How to solve it?

Ambient temperature is too high leading to semiconductor chip high and low temperature tester failure: for semiconductor chip high and low temperature tester ambient temperature is clearly defined, if the ambient temperature is too high will inevitably lead to the phenomenon of low temperature drop.

Condenser fan failure: detect whether the fan motor is blocked or burned out, the fan does not rotate or the wind speed is reduced as a result.

Refrigeration liquid leakage: through soapy water, detergent to smear on the surface of the copper tube,semiconductor failure analysis detect leaks, make up for leaks, add refrigeration liquid can be.

Semiconductor chip high and low temperature testing machine compressor failure: check whether the refrigeration compressor is working, if the failure, do not move need to call the manufacturer, repair or replacement of the compressor.

Semiconductor chip high and low temperature testing machine condenser dust treatment: condenser should be regular monthly maintenance, the use of vacuum cleaner will condenser cooling mesh attached to the dust sucked out or the use of high-pressure air spray dust.

Semiconductor chip high and low temperature tester check over-temperature protection: semiconductor chip high and low temperature tester operation, over-temperature protection of the set value. The temperature inside the test chamber rises to the set point of the over-temperature protection, the power supply of the heater will stop, "OVERHEAT" over-temperature light prompts but the fan is still running,aotomatic prober if a long period of time and unattended operation, before running, please be sure to check the over-temperature protector, whether it is set properly.

Semiconductor chip high and low temperature tester box internal and external cleaning and maintenance: semiconductor chip high and low temperature tester in the operation of the internal impurities should be removed. The power distribution room should be cleaned at least once a year, and vacuum cleaner can be used to remove the dust inside the room. The outside of the box must also be cleaned more than once a year, cleaned with soapy water can be wiped first.

I believe that the user understands the semiconductor chip high and low temperature testing machine failure can be a good use of semiconductor chip high and low temperature testing machine.
