Description

PCB board with detect character circle PAD

Technical Field

The utility model belongs to the technical field of the PCB board detects, concretely relates to PCB board with detect character circle PAD.

Background

A Printed Circuit Board (PCB), also called a printed circuit board, is an important electronic component, which is a support for electronic components and a carrier for electrical connection of electronic components. Along with continuous miniaturization, lightness, the multi-functional of electronic product, the circuit board size is also littleer and more, wiring density is higher and more, and the shape of circuit board is also diversified, and special-shaped circuit board is often used in each field. Accordingly, multi-layer high density interconnect printed circuit boards with blind drilled counterbore designs are becoming an important part of a variety of high technology electronic products.

In the prior art, whether the PCB is missed to drill the blind hole is generally checked manually, but the detection method is easy to miss detection due to the detection level of a quality inspector, so that the missed drilled blind hole flows to a client side, the packaging and fixing of components are influenced, the quality of the PCB is greatly reduced, the detection efficiency and the detection accuracy are influenced, the detection is not completed by adopting a newly added blind hole, the equipment investment cost is increased, and the customer experience is reduced.

SUMMERY OF THE UTILITY MODEL

The embodiment of the application provides a PCB board with detect character circle PAD, through the setting of character circle PAD, has solved the artifical inaccurate problem of hourglass brill blind hole that detects, has realized improving the PCB board and has detected the degree of accuracy of leaking the brill blind hole, is difficult for omitting, effectively improves detection efficiency, effectively ensures PCB's quality, and the good encapsulation of guarantee components and parts is with fixed, and detects with low costs, the strong operability.

The technical scheme provided by the embodiment of the application is as follows:

the PCB comprises a body, wherein the surface of a blind hole to be drilled of the body is provided with a character circle PAD.

The utility model discloses in, through boring blind hole site character circle PAD on the surface at treating of body, carry out outward appearance detection to the PCB board through base plate outward appearance/color and luster inspection machine, if PCB bores the blind hole in the hourglass, character circle PAD still stays on the PCB board, detect the back through base plate outward appearance/color and luster inspection machine, detectable discernment and suggestion multiple spot are unusual, thereby effectively improve the detection accuracy, improve detection efficiency, effectively ensure PCB's quality, guarantee the good encapsulation and fixed of components and parts, and detection cost is low, strong operability, can stop to bore the customer complaint that the blind hole arouses because of the hourglass.

Further, the diameter of the character circle PAD is smaller than the diameter of the blind hole of the body by 0.25-0.3 mm.

Furthermore, the thickness of the character circle PAD is 0.08-0.2mm, and through the arrangement, the function of the blind hole cannot be influenced by the character circle PAD after the blind hole is drilled, so that the quality of the blind hole is guaranteed.

Further, the character circle PAD is an ink character circle PAD.

Furthermore, the ink character circle PAD is a lithographic ink character circle PAD, and an ink print printed on a printed matter through the lithographic ink is very thin, so that a prompt effect is effectively achieved, the blind hole function is not influenced, and the quality of the PCB is effectively guaranteed.

Further, the character circle PAD is a white character circle PAD.

The utility model has the advantages that:

through the setting of character circle PAD, solved artifical detection and leaked the unsafe problem of boring the blind hole, realized improving the PCB board and detected the degree of accuracy of leaking boring the blind hole, be difficult for omitting, effectively improve detection efficiency, effectively ensure PCB's quality, guarantee components and parts's good encapsulation and fixed, and detect with low costs, the strong operability.
