Technical field
The utility model relates to a kind of accurate wiring board of PCB multilayer with Novel protective structure.
Background technology
The accurate wiring board of existing PCB, there is no special-purpose cooling mechanism, can only rely on the natural heat dissipation of plate body, or locate to increase radiator fan etc. at the large device of caloric value (as CPU), but radiating effect is good not, plate body easily seriously causes line fault because generating heat;
In addition, the accurate wiring board barrier propterty of existing PCB multilayer is not good, therefore it structurally need to be reinforced.
Therefore be necessary to design the accurate wiring board of a kind of novel PCB multilayer.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of accurate wiring board of PCB multilayer with Novel protective structure, and this accurate wiring board radiating effect of PCB multilayer with Novel protective structure is good, and strong shock resistance, can long-term stable operation.
The technical solution of utility model is as follows:
The accurate wiring board of PCB multilayer with Novel protective structure is provided with the first heat radiation module and the second heat radiation module on substrate (1);

The relative both sides of substrate are respectively provided with an end chuck (8) for reinforcing.
The first described heat radiation module and the second heat radiation module are a plurality of.
Beneficial effect:
The accurate wiring board of PCB multilayer with Novel protective structure of the present utility model, by the square shape sheet heat dissipating layer in the first heat radiation module and the second heat radiation module and disc heat dissipating layer and the preliminary heat radiation of the post that leads realization, more further dispels the heat by radiator.
The fold that is positioned at the square shape sheet heat dissipating layer of base lower surface and the outer surface setting of disc heat dissipating layer has increased the area of heat radiation, better heat-radiation effect.
In addition, this square shape sheet heat dissipating layer with the accurate wiring board of PCB multilayer of Novel protective structure is all connected with ground wire with disc heat dissipating layer, and the antijamming capability of whole pcb board is strengthened.
The effect of end chuck is to reinforce substrate, makes it when receiving that external force is hit in a state of excitement, not be prone to interlayer dislocation and causes fault;
Generally speaking, the accurate wiring board radiating effect of this PCB multilayer with Novel protective structure is good, and strong shock resistance, can long-term stable operation.
