Abstract
It the utility model is related to PCB production fields, there is provided a kind of fool proof stamping die being used for after PCB secondary drilling processes, including die ontology（1）And the red needle that body surface is set（2）, the position of all secondary drillings is correspondingly arranged red needle（2）, red needle（2）Size pass through the hole that secondary drilling process is bored.When there is the plate that non-secondary drilling or secondary drilling do not drill out completely and carrying out stamping, just occur can not stamping, effectively the bad plate control that drills is prevented bad plate from entering into next process, reduces production fraction defective in current fabrication process.
Description
Technical field
It the utility model is related to PCB production fields, and in particular to a kind of fool proof punching press being used for after PCB secondary drilling processes
Mould.
Background technology
During the manufacturing of PCB, after core plate is pressed, it need to drill on the multi-layer board obtained by pressing and make Kong Jin
Categoryization.When that need to make the hole of different attribute on multilayer boards, such as metallize filling holes with resin and plated-through hole, need to be different
Made respectively in process.Existing production process is typically:Normal preceding process one is by target-shooting machine in multiple-plate drilling target
Place's drilling simultaneously carries out once one electric plating of whole board one of the heavy copper of drilling one filling resin one according to drilling target setting drilling coefficient and grinds
Process after plate-secondary drilling one sinks one electric plating of whole board one of copper normally.Secondary drilling is one of important procedure of PCB productions.
In order to improve the shaping producing efficiency of PCB, for complex contour and larger order is measured, makes and is molded in PCB
When, generally use stamping mode（I.e. mould punching is molded）, but while stamping, the partial hole in plate there are in preceding process
Secondary drilling leakage is bored, and direct goods dispatch to client, causes half-finished product plate not use；The credit rating of client is greatly reduced.
Utility model content
Technical problem to be solved in the utility model is：A kind of mould is provided；Pcb board leakage secondary drilling stream in order to prevent
Journey, or operator's leakage, a part of PCB does not carry out secondary drilling, is corresponding secondary brill in mould when stamping is molded
Hole site uniformly sets red needle, when the plate that the non-secondary drilling of appearance or secondary drilling do not drill out completely carries out stamping, will go out
Now can not stamping, effectively prevent bad plate from entering into next process in current fabrication process the bad plate control that drills.
Technical problem to be solved in the utility model is achieved by the following technical programs：
A kind of fool proof stamping die being used for after PCB secondary drilling processes, including die ontology 1 and body surface are set
Red needle 2, the position of all secondary drillings is correspondingly arranged red needle 2, and the size of red needle 2 passes through secondary drilling process institute
The hole of brill, but its size can not pass through the hole that secondary drilling process does not drill out completely.The normal dia in the hole that secondary drilling is bored
For 0.8-1.5mm.
As to further improvement of the utility model, the red needle 2 mould sheet is arranged in the form of being grouped and arrange
On body 1,6 row are provided with altogether, and each column sets 5 groups of red needles 2, and every group is made of two red needles 2.
As to further improvement of the utility model, the red needle 2 is circular red needle.
As to further improvement of the utility model, the diameter of the red needle 2 is than hole that secondary drilling process is bored
The small 0.2-0.4mm of diameter.
The beneficial effects of the utility model are：
The 1st, fool proof red needle is set, when plate is carried out stamping, PCB occurs what non-secondary drilling or secondary drilling did not drilled out completely
Situation, Stamping Steps can not carry out, and can pick out the PCB for leaking through secondary drilling process.
2nd, all secondary drilling positions are all set into fool proof stamping red needle, prevents secondary drilling from the situation of breaking occur, also
With 100% secondary drilling can be prevented not to be drilled full quality and miss.
3rd, the operating pressure of product examine is reduced.
Brief description of the drawings
Fig. 1 is that a kind of structure for the fool proof stamping die being preferably used in after PCB secondary drilling processes of the utility model is shown
It is intended to.
Embodiment
Explanation and embodiment further illustrate the utility model below in conjunction with the accompanying drawings.
Drawing reference numeral in Fig. 1 is die ontology 1, red needle 2.
As shown in Figure 1, a kind of fool proof stamping die being preferably used in after PCB secondary drilling processes, red needle 2 is with the row of packet
The form of row is arranged on die ontology 1, is provided with 6 row altogether, and each column sets 5 groups of red needles 2, and every group is made of two red needles 2.
Wherein, the red needle 2 is circular red needle, its a diameter of 0.4mm, the hole that its applicable secondary drilling process is bored
A diameter of 0.8mm.In application, after secondary drilling process, if the non-secondary drilling of PCB appearance or secondary drilling of stamping be not complete
Situation about drilling out entirely, will be unable to be positioned on mould, and Stamping Steps can not carry out.
In other preferred embodiments, red needle 2 is square red needle or hexagonal red needle or oval red needle or different in nature red needle, its
Size can pass through the hole that applicable secondary drilling process is bored,
Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to
Assert that the specific implementation of the utility model is confined to these explanations.For the ordinary skill of the utility model technical field
For personnel, without departing from the concept of the premise utility, some simple deduction or replace can also be made, should all be regarded
To belong to the scope of protection of the utility model.
