Layer.
By using said program, since silane coupling agent layer has fabulous adhesion effect, by fiberglass gridding cloth
The both sides of layer are coated with silane coupling agent layer, at this time between glass chopped strand mat layer and aluminum substrate layer and nano-sized carbon heat dissipation film
Bonding firmness will be relatively good, can finally reduce the possibility that this kind of copper-clad plate generation is cracked between layers.
The utility model is further arranged to：Multiple heat emission holes are offered on the aluminum substrate layer.
By using said program, multiple heat emission holes on aluminum substrate layer can increase the heat exchange between air, most
Preferable heat dissipation effect can be further functioned as eventually.
The utility model is further arranged to：The side of the heat emission hole offers a plurality of heat-radiating ring-groove.
By using said program, using a plurality of heat-radiating ring-groove of heat emission hole side, the presence of heat-radiating ring-groove can increase
Contact area between heat emission hole and air so as to further increase the heat exchange between air, can finally further serve as
To preferable heat dissipation effect.
In conclusion the utility model has the advantages that：
1. using the nano-sized carbon heat dissipation film between aluminum substrate layer and copper foil layer, since nano-sized carbon heat dissipation film has fabulous dissipate
Thermal effect, while using the glass chopped strand mat layer between nano-sized carbon heat dissipation film and aluminum substrate layer, due to fiberglass gridding
Layer of cloth is in latticed, and the poor event permeability of fibre compact degree of grid cloth is relatively good, so as to further function as
The bad situation of relatively effective improvement aluminium heat dissipation finally can be realized in the effect of heat dissipation；
2. the radiating groove being evenly spaced on using glass chopped strand mat layer side, and radiating groove is far from glass fiber mesh
One end of scrim layer side is located at the position of aluminum substrate layer symmetrical centre, and radiating groove can further function as heat dissipation at this time
Effect；
3. since silane coupling agent layer has fabulous adhesion effect, the both sides of glass chopped strand mat layer are coated with
Silane coupling agent layer, the bonding firmness between glass chopped strand mat layer and aluminum substrate layer and nano-sized carbon heat dissipation film is just at this time
Can be relatively good, it can finally reduce the possibility that this kind of copper-clad plate generation is cracked between layers.
