Method of manufacturing heat dissipation module
A method of manufacturing heat dissipation module is provided. The method includes: providing a main body; disposing a thermal interface material (TIM) layer on the main body; applying a first pressure to a surface of the TIM layer away from the main body in stages regionally; and applying a second pressure to an entire portion of the surface at a same time.
1. A method of manufacturing a heat dissipation module, the method comprising:
providing a main body;
disposing a thermal interface material (TIM) layer on the main body;
applying a first pressure to a surface of the TIM layer away from the main body in stages regionally;
applying a second pressure to an entire portion of the surface at a same time after the first pressure is applied; and
abutting the surface against a chip after the second pressure is applied.
2. The method of claim 1 , wherein the surface is divided into a plurality of regions, and applying the first pressure comprises:
applying the first pressure to the regions one by one.
3. The method of claim 1 , wherein applying the first pressure comprises:
rolling on the surface by a roller to apply the first pressure to the surface regionally.
4. The method of claim 1 , wherein applying the first pressure comprises:
adjusting the first pressure applied to the surface.
5. The method of claim 1 , wherein applying the second pressure comprises:
pressing on the main body by a first pressing tool; and
pressing on the entire portion of the surface by a second pressing tool, wherein the second pressing tool at least partially aligns with the first pressing tool.
6. The method of claim 1 , further comprising:
disposing a flux between the main body and the TIM layer.
7. The method of claim 6 , wherein applying the second pressure comprises:
heating up the flux.
8. The method of claim 7 , wherein heating up the flux comprises:
heating up the flux to a temperature, wherein a range of the temperature is between 145 and 170 degree Celsius.
9. The method of claim 8 , wherein heating up the flux comprises:
maintaining the temperature within a time period, wherein a range of the time period is between 2 and 3 minutes.
10. The method of claim 7 , wherein applying the second pressure comprises:
applying the second pressure in a chamber,
the method further comprises:
providing a working gas in the chamber.
11. The method of claim 10 , wherein the working gas includes nitrogen and formic acid.
12. A method of manufacturing a heat dissipation module, the method comprising:
providing a main body;
disposing a flux on the main body;
disposing a thermal interface material (TIM) layer on a side of the flux away from the main body;
applying a first pressure to a surface of the TIM layer away from the main body in stages regionally;
applying a second pressure to an entire portion of the surface at a same time after the first pressure is applied; and
abutting the surface against a chip after the second pressure is applied.
13. The method of claim 12 , wherein the surface is divided into a plurality of regions, and applying the first pressure comprises:
applying the first pressure to the regions one by one.
14. The method of claim 12 , wherein applying the first pressure comprises:
rolling on the surface by a roller to apply the first pressure to the surface regionally.
15. The method of claim 12 , wherein applying the first pressure comprises:
adjusting the first pressure applied to the surface.
16. The method of claim 12 , wherein applying the second pressure comprises:
pressing on the main body by a first pressing tool; and
pressing on the entire portion of the surface by a second pressing tool, wherein the second pressing tool at least partially aligns with the first pressing tool.
17. The method of claim 12 , wherein applying the second pressure comprises:
heating up the flux.
18. The method of claim 17 , wherein heating up the flux comprises:
heating up the flux to a temperature, wherein a range of the temperature is between 145 and 170 degree Celsius.
19. The method of claim 18 , wherein heating up the flux comprises:
maintaining the temperature within a time period, wherein a range of the time period is between 2 and 3 minutes.
20. The method of claim 17 , wherein applying the second pressure comprises:
applying the second pressure in a chamber,
the method further comprises:
providing a working gas in the chamber.
21. The method of claim 20 , wherein the working gas includes nitrogen and formic acid.
