Description

A kind of accurate wiring board of PCB multilayer that prevents high multilayer blind plate off normal

Technical field

The utility model relates to a kind of accurate wiring board of PCB multilayer that prevents high multilayer blind plate off normal.

Background technology

The accurate wiring board of PCB multilayer generally possesses a lot of blind holes, in the process of the accurate wiring board of preparation PCB multilayer and in the process of the accurate wiring board of use PCB multilayer, easily under the effect of external force, cause the each level of the accurate wiring board of PCB multilayer that dislocation occurs and cause the off normal of blind hole, thereby cause wiring board circuit to open circuit or short trouble, therefore, be necessary to design a kind of accurate wiring board of PCB multilayer that prevents high multilayer blind plate off normal.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of accurate wiring board of PCB multilayer that prevents high multilayer blind plate off normal, this accurate wiring board of PCB multilayer that prevents high multilayer blind plate off normal adopts zigzag clamp bar to reinforce the surrounding of square plate body, adopt 5 copper posts that evenly arrange to prevent from forming the relatively moving of each layer of veneer of pcb board, can effectively prevent blind hole off normal.

The technical solution of utility model is as follows:

The accurate wiring board of PCB multilayer that prevents high multilayer blind plate off normal, is respectively equipped with a reinforcing strip (2) in four side edge of square plate body (1); Each reinforcing strip is made up of a bar-like member (23) and 2 intermediate plates (21); 2 intermediate plates are all vertical with bar-like member; Between 2 intermediate plates and a bar-like member, form one for clamping the groove (21) at described square plate body edge;

The edge of the front and back of square plate body is equipped with zigzag depressed part (11); The outside of described each intermediate plate is zigzag; The jagged edge of intermediate plate is inlaid in the zigzag depressed part of described square plate body;

On square plate body, Si Jiaohe center is respectively provided with 1 columniform copper post (3) along the thickness direction of square plate body.

The diameter of copper post is 1mm, and the thickness of square plate body is 1.5mm.

Beneficial effect:

The accurate wiring board of PCB multilayer that prevents high multilayer blind plate off normal of the present utility model, adopt the zigzag depressed part on zigzag clamp bar and square plate body chimeric, thereby the surrounding of reinforcing square plate body can effectively be resisted external impacts plate body.

In addition, adopt 5 copper posts that evenly arrange to prevent from forming the relatively moving of each layer of veneer of pcb board, can effectively prevent blind hole off normal, and can play square plate body reinforcement effect on the whole.
