With sizableness.
Specifically, one surface of substrate is the one side in face of the pyrotoxin.
Preferably, the roughness of the roughening lines is 2~20Ra.
In a preferred embodiment, the roughening lines is circle X-shape.
In another preferred embodiment, the roughening lines is " well " font.
In another preferred embodiment, the roughening lines is " X " font.
Preferably, the roughening lines generally rectangle or square, side length are parallel with the length of the substrate or width.
Preferably, there are three the roughening lines is set.
In the present invention, the roughening lines is suppressed by press machine punching press in upper mould and lower mould.This hair
It is bright the specific lines and monnolithic case of roughening lines not to be limited in any way, any line under can be Mold Making technology and allowing
Road and shape, but need to guarantee roughness between 2~20Ra.
The temperature-uniforming plate bottom plate of a kind of roughing in surface provided by the invention, by press machine upper die of stamping die and lower mould pressure
It makes, roughening lines is uniform, careful and pattern is various, and production is high-efficient and yield is high；The lines pattern of roughening lines,
Global shape and roughness can be set according to the installation site of temperature-uniforming plate and shape, size and weight of temperature-uniforming plate of pyrotoxin etc.
Meter, flexibility is high, strong applicability；
Design roughening lines, does not have to welding, the quality of temperature-uniforming plate can be improved from procedure for producing angle directly on substrate
And production efficiency, it saves human and material resources, reduces producing cost, improve production, have high economic benefit；
The roughening lines of design, from functional perspective analyze, heat conduction and heat radiation area can be increased, greatly promote heat dissipation effect with
And the adhesion strength of heat-conducting glue, improve the reliability of product.
