Suitable for IC testing of all kinds of semiconductor chips,flash memory Flash/EMMC, PCB circuit boards, opticalcommunications,electronic industries, etc.

Descrições

1. Widely used in high and low temperature testing of semiconductor equipment.Cold and heat source of electronic equipment at high temperature and low temperature;
2. Independent refrigeration circulating air units;
3. Can work continuously for a long time, automatic defrosting, defrosting process does not affect the storage temperature;
4. Modular design, easy replacement of spare machine (if there are 10 machines, as long as a standby unit can);
5. Solve frequent open and close doors, evaporating system frosting problems;Evaporation system defrosting process does not affect.
6. Construct a set of high and low temperature and constant greenhouse (according to the drawings provided, the box can be joined together like building blocks to connect the electricity and water and set the temperature to work)

It is used to cool the gas (non corrosive) or recover it as non corrosive gas by condensation and liquefaction.

Pressure resistance of gas heat exchange system: 25bar; The temperature range is – 40 ℃ ~ – 75 ℃, which can meet different temperatures;

The secondary subcooling technology is adopted, with rapid refrigeration and low refrigeration temperature;

Semi closed piston compressor, scroll flexible compressor and fully closed piston compressor of imported brands are adopted;

The evaporator adopts casing heat exchanger, which has the advantages of small volume, long residence time and high efficiency;

Danfoss expansion valve and Emerson electronic expansion valve are adopted, with high temperature control accuracy;

Siemens plcs7-200 / 300 and lneya touch screen display are used for automatic control operation;

The whole machine is installed. The system has been tested in the factory. Users only need to install the refrigerant pipeline and cooling water pipeline to run;

Factory test: each refrigeration unit shall be tested with load in the factory for no less than 12 hours;
