Abstract
The utility model discloses an internal layer error-proofing printed circuit board which includes target holes and error-proofing holes which are arranged in two corner areas of two opposite corners of an internal layer printed circuit board. Because the number of the error-proofing holes in one corner area is inconsistent with the number of the error-proofing holes in the other corner area, an operator can easily identify the reversed layout phenomenon or the contraposition deviation phenomenon, so the product reworking and discarding problems caused by the above phenomena are avoided, and consequently the working efficiency is improved, and the production cost is reduced.
Description
Technical field
The utility model relates to a kind of printed circuit board, is specifically related to a kind of internal layer mistake proofing printed circuit board.
Background technology
Printed wiring board need and develop and realize figure transfer in manufacturing process through exposure; In operating process, the accurate ten minutes of contraposition is important, in case the contraposition inaccuracy can cause skew; Thereby cause scrapping; Particularly in internal layer manufacturing process, the effect of internal layer generally is that to be used for the function ratio of conducting more, therefore; The big copper sheet of the fewer or monoblock of internal layer circuit; Deviation appears in contraposition easily in the process of contraposition, and is at present, as shown in Figure 1; A lot of general printed wiring boards are provided with 2
and grow the target hole 1 that the limit is provided with 1
at the minor face of plate usually; But because the contraposition employee is skilled inadequately during to bit manipulation, produce inclined to one side phenomenon in the time of can causing the printed wiring board contraposition, and the phenomenon that can cause printed circuit board to put back serious the time; Directly cause product rejection, improved production cost greatly.
The utility model content
The purpose of the utility model is to provide a kind of internal layer mistake proofing printed circuit board, can handled easily person easily identification put back or to the printed wiring board of off normal, effectively problem is scrapped in control, reduces cost.
For realizing above-mentioned purpose, the utility model has adopted following technical scheme:
A kind of internal layer mistake proofing printed circuit board comprises the target hole, and two corner areas that also are included in one of them diagonal angle of said internal layer printed circuit board are provided with the mistake proofing hole.
Preferably, as further technological improvement, in the utility model, the mistake proofing hole number of two corner areas in zone at said diagonal angle is inconsistent.
Preferably, as further technological improvement, in the utility model, be provided with spacing between said mistake proofing hole and the said target hole.
The utility model contrast prior art has following advantage: through the inconsistent mistake proofing of hole number hole is set; Let the operator discern easily and put back the perhaps phenomenon of contraposition skew; The product of having avoided therefore causing is done over again and is scrapped problem, thereby has improved operating efficiency, has reduced production cost.

Embodiment
Existing with reference to accompanying drawing, further explain the utility model.
As shown in Figure 2, a kind of internal layer mistake proofing printed circuit board graphics field 2 of the utility model first embodiment, two corner areas at one of them diagonal angle of layer printed circuit board are provided with mistake proofing hole 3 within it.
In order better to distinguish the direction of plate and to guarantee the high accuracy contraposition; Mistake proofing hole 3 numbers of two corner areas are inconsistent in the zone at diagonal angle, and the number in mistake proofing hole 3 can be provided with according to the production needs voluntarily, in the present embodiment; The number lower left corner in mistake proofing hole 3 is 3, and the upper right corner is 5.
In order better to distinguish the direction of plate and to guarantee the high accuracy contraposition to be provided with spacing between mistake proofing hole 3 and the target hole 1.
As shown in Figure 3; A kind of internal layer mistake proofing printed circuit board graphics field 2 of the utility model second embodiment; Two corner areas at one of them diagonal angle of layer printed circuit board are provided with mistake proofing hole 3 within it, and the number in mistake proofing hole 3 and position are that the lower left corner is 5, and the upper right corner is 3.
As shown in Figure 4; A kind of internal layer mistake proofing printed circuit board graphics field 2 of the utility model the 3rd embodiment; Two corner areas at one of them diagonal angle of layer printed circuit board are provided with mistake proofing hole 3 within it, and the number in mistake proofing hole 3 and position are that the upper left corner is 3, and the lower right corner is 5.
As shown in Figure 5; A kind of internal layer mistake proofing printed circuit board graphics field 2 of the utility model the 4th embodiment; Two corner areas at one of them diagonal angle of layer printed circuit board are provided with mistake proofing hole 3 within it, and the number in mistake proofing hole 3 and position are that the upper left corner is 5, and the lower right corner is 3.
Above-described the utility model execution mode does not constitute the qualification to the utility model protection range.The modification of being done within any spirit and principle at the utility model, be equal to replacement and improvement etc., all should be included within the claim protection range of the utility model.
