How to judge the quality of precision electronic heat sinks? 'Hardware'

Precision electronic heat sinks are mainly used in electronic components, and precision electronic heat sinks do not have an external power supply, and there will be other materials such as copper precision electronic heat sinks or alloy materials, but many friends do not know how to judge electronic heat sinks Quality, let's briefly introduce the hardware below. Three methods to judge the quality of precision electronic heat sinks: 1. The surface roughness and flatness of the precision electronic heat sink contacting the mesa directly affects the contact thermal resistance and pressure drop. 2. The quality of the precision electronic heat sink material and manufacturing process (cracks, shrinkage holes, etc.), inferior materials and rough and defective processes will directly affect the thermal conductivity of the radiator. 3. Disc springs for electronic radiators should ensure that the free height should be stable after being flattened for 24 hours, otherwise the springs may fail after a period of use, which will result in poor contact between the radiator and the die. The above is how to judge the quality of precision electronic heat sinks. We can judge according to the above methods when purchasing heat sinks.
