Abstract

The utility model relates to a PCB board, especial its face structure that relates to. The utility model aims to provide a process convenient PCB board with position circle protective layer. A PCB board with position circle protective layer, has main part board and waste material district, is equipped with the position circle on the main part board, above -mentioned position circle overlying ground matcoveredn. This neotype benefit is the protective layer that increases the position circle through printing ink, need not to increase the process at the product in -process, can directly design the protective layer part at the solder mask in the engineering data, can once only directly accomplish when printed wiring board silk screen printing, reduces the production degree of difficulty, does not increase manufacturing cost again.

Description

There is the pcb board of centring ring protective layer

Technical field

This utility model relates to pcb board, in particular to its board face structure.

Background technology

Pcb board is exactly printed circuit board (PCB), almost appears in the middle of each electronic equipment. And electronic component is just set on the pcb board of different sizes. Along with electronic equipment becomes increasingly complex, it is necessary to part get more and more, the circuit on pcb board and part are also more and more intensive. This plate is constituted substrate by insulated heat unbending material, on surface it can be seen that tiny line material be Copper Foil, originally Copper Foil is to cover on whole plank, and part is etched and disposes in the fabrication process, and the part stayed reforms into netted tiny circuit. These circuits are referred to as wire or claim wiring, and are used for providing the circuit of part on pcb board to connect.

Along with developing rapidly of electron trade, the trend of electronic product microminiaturization is day by day obvious, and one piece of pcb board is except fixing various little electronic components, and its major function is also provided with being electrically connected to each other of various electronic component. Along with the development of information technology, electronic equipment also becomes increasingly complex, it is necessary to part get more and more, the circuit on pcb board and part are also more and more intensive. In pcb board manufacturing, pcb board is constituted substrate by insulated heat unbending material, on surface it can be seen that tiny line material be Copper Foil, originally Copper Foil is to cover on whole plate, part is etched and disposes in the fabrication process, the part stayed reforms into netted tiny circuit, and these circuits are referred to as wire, and for providing the circuit of part on pcb board to connect.

In printed board forming process; it is required for adopting hole, location to position, and along with the raising of current automation equipment, the built on stilts condition in hole, location is also accordingly increased; this project is to have centring ring protective layer printed board for producing one; owing to current printed board centring ring copper band is exposed in atmosphere, cause oxidation in various degree, at automatic punching equipment to location None-identified; the purpose of this new design is in that to solve the problems referred to above; reduction is scrapped, and strengthens equipment identification ability, reduces customer complaint.

Utility model content

This utility model purpose is to provide a kind of pcb board with centring ring protective layer easy to process.

The technical scheme realizing this utility model purpose is as follows: a kind of pcb board with centring ring protective layer, has main board and garbage area, and main board is provided with centring ring, is coated with protective layer above above-mentioned centring ring. Above-mentioned protective layer is rounded or square according to arranging position.

This novel benefit is to be increased the protective layer of centring ring by ink; without increasing operation in product process, in engineering data, protective layer part can directly be designed at solder mask, can disposable be done directly when printed wiring board silk-screen; reduce production difficulty, do not increase again production cost.

Accompanying drawing explanation

Fig. 1 is this utility model schematic diagram.

Detailed description of the invention

Seeing Fig. 1, a kind of pcb board with centring ring protective layer, have main board 1 and garbage area 3, main board is provided with centring ring 100, is coated with protective layer 2 above above-mentioned centring ring 100. Above-mentioned protective layer 2 is rounded or square according to arranging position.

This is novel when being embodied as on hole, location and neighboring area is especially for being built up on technique edges protective mulch, if on main board angle, protective layer is designed to square, if being just designed to circle on limit. Protective layer embodies on the film and silk screen, is once formed when silk-screen, forms centring ring protective layer, it is prevented that the equipment that the oxidation in various degree of centring ring position causes not can recognise that, or identifies that the unclear hole, location caused trains off and scrap.

Obviously, above-mentioned detailed description of the invention of the present utility model is only for clearly demonstrating this utility model example, and is not the restriction to this utility model embodiment. For those of ordinary skill in the field, can also be easy to make other pro forma change or replacement on the basis of the above description, and these change or replacement also will be contained within the protection domain that this utility model is determined.

Claims

1. a pcb board with centring ring protective layer; there is main board (1) and garbage area (3); main board is provided with centring ring (100), it is characterised in that: it is coated with protective layer (2) above above-mentioned centring ring (100).

2. the pcb board with centring ring protective layer according to claim 1, it is characterised in that: above-mentioned protective layer (2) is rounded or square according to arranging position.
