What are the quality requirements of electronic radiator？Intersection

Electronic radiator requirements:
1. The surface of the heat dissipation is corroded, cracks, etc.;
2 Piece plate of tablets ,,, dish spring spring spring, and water -cooled heat sink -conductive batteries should be
3 The most allowable value of the roughness of the heat dissipation to roughness is 3.2, m;
4 The flatness of the heat dissipation countertop is lower differential thermostat than level 9;
5 The standard for hysteresis thermostat semiconductor devices (including thermostat temperature controller heater insulation parts insulating component insulation parts insulation parts);
6 The and insulating parts of the radiator should meet the compliance that meets the compliance ((semiconductor device radiator insulation and
7 The tight torque of the heat sink semiconductor should be related to the product of the product;
8 Tablet -shaped installation center positioning: 2.5mm, high LMM above the table.
