Many people who want to buy a radiator should have a basic understanding of how to choose a radiator. The most basic choice of an electronic radiator is that the surface of the electronic radiator needs to be flat, but this is only one of them. The surface quality of electronic radiators mainly needs to meet the following standards:

1. The flatness of the electronic radiator table is not less than 9;

2. The surface of the electronic heat sink should be free from shrinkage, corrosion, cracks and other defects;

3. The maximum allowable value of the surface roughness Ra of the electronic heat sink table is 3.2 meters;

4. The maximum allowable value of the surface roughness Ra of the electronic radiator table is 3.2 meters;

5. The tightening torque or tightening pressure of the electronic radiator and power semiconductor installation should meet the relevant regulations of the device product standard;

6. The metal fasteners of the flat radiator (pressing plate, gland, disc spring), and the conductive sheet of the water-cooled radiator should be protected by plating;

7. Fasteners and insulating parts special for electronic radiators should meet the standards, and radiator insulating parts and fasteners for power semiconductor devices;

8. The surface of the radiator (including radiator, fasteners and insulating parts) used in humid tropical power semiconductor devices should be treated with protection, and its resistance to moisture, salt spray and mold should meet the corresponding tropical power semiconductor Device standards.

Electronic radiators that meet the above eight standards can be regarded as surface quality up to standard. Dongguan Zhigao provides you with electronic radiators that meet the quality standards.
