Face have gap, and with ventilative backing plate of taking.
Preferably, the thickness of the base is greater than 5OZ.
Thicker base can make have more gap between wiring board and ventilative backing plate, conducive to consent process into
Row.
Preferably, the copper post includes the support column being fixedly connected with base and the support for being set to the support top end
Platform.
Under the premise of guaranteeing the area on copper post top, the part copper material of copper post lower part is removed, it can be with the use of less copper material
Amount, while mitigating the weight of ventilative veneer, save the cost is convenient for operation.
Further, the upper end of the support column is provided with reinforcement block, the reinforcement block respectively with the support platform and
Support column is fixedly connected.
Reinforcement block is the structure around copper post fixed setting, and the upper end is fixedly connected with support platform, and reinforcement block is for adding
The bonding strength of strong support column and support platform.
Further, the side of the reinforcement block is disposed obliquely inwards, and forms supporting surface.
Further, the angle of the supporting surface and horizontal plane is 40-50 °.
Inclined support surface can reduce the weight of the utility model with the materials of less copper material, reduce cost of manufacture；Together
When, quench hardening processing can be carried out to supporting surface, keep it more preferable for the support strength of support platform.
Further, the top of the support platform offers several through-holes, and the orthographic projection of the through-hole is located at the branch
The outside of the orthographic projection of dagger.
Through-hole in support platform in support platform for blocking when the hole of consent circuit board, so that in the hole of circuit board
Air can be penetrated from through-hole, to guarantee going on smoothly for consent process.
Further, the upper end of the through-hole is provided with chamfering.
Chamfering can take out the sharp edges of through-hole, and circuit board is further prevented to be scratched.
The principles of the present invention, effect are further illustrated below with reference to above-mentioned technical proposal:
Copper post is arranged on the basis of copper-clad plate in the utility model, is supported with copper post to circuit board, make circuit board with
There is gap between ventilative backing plate, guarantee the gas permeability in the hole on circuit board, to be conducive to the progress of consent process.
