Abstract
The utility model relates to a PCB board, and particularly to the shape structure. The aim of the utility model is to provide the PCB board which is easy for processing, more satisfies the processingrequirement and is provided with an anti-scrap hole. The PCB board with the anti-scrap hole comprises the anti-scrap hole which is provided for the profile hole processing step. The anti-scrap hole can be positioned in the profile hole to be processed and can also be intersected with the profile hole to be processed. Because of the existence of the anti-scrap hole, when the PCB board is drilled, the scraps remained in drilling can be effectively removed, and simultaneously the drill break can be prevented to some extent. Thus the production efficiency is increased and the production cost is saved.
Description
Technical field
The utility model relates to pcb board, relates to its contour structures especially.
Background technology
Pcb board is exactly a printed circuit board (PCB), almost can appear in the middle of each electronic equipment.And electronic component just is set on the pcb board of different sizes.Along with electronic equipment becomes increasingly complex, the part that needs is more and more, and circuit and part on the pcb board are also more and more intensive.This plate is heat insulation by insulation, also unbending material constitutes substrate, the tiny line material that can see on the surface is a Copper Foil, originally Copper Foil is to cover on the whole plank, and part is etched in manufacture process disposes, and the part that stays has just become netted tiny circuit.These circuits are known as lead or claim wiring, and are used to provide the circuit connection of part on the pcb board.
Existing pcb board all has irregularly-shaped hole usually, and it often connect not to use as circuit, but is used for pcb board and erection unit is connected.When adding man-hour at drilling machine or milling machine, directly in the processing of profiled holes zone, can stay the detritus of many borings, these detritus are stayed on the plate face can influence the carrying out of printing operation, and manually has to carry out cleaning work, has increased workload; Directly on the plate face, spud in addition, damage drill bit easily even cause drill bit to fracture.
The utility model content
The purpose of this utility model provides a kind of pcb board with anti-dandruff hole of processing simply, more meeting processing request.
The technical scheme that realizes the utility model purpose is as follows:
A kind of pcb board with anti-dandruff hole has the anti-dandruff hole of preparing for following road irregularly-shaped hole manufacturing procedure on the above-mentioned pcb board.Above-mentioned anti-dandruff hole profile can be positioned at the irregularly-shaped hole inside that needs processing, also can intersect with the irregularly-shaped hole of needs processing.
Because the existence in anti-dandruff hole when holing to pcb board, can effectively be removed the detritus that stays because of boring, also prevent breaking of rod head simultaneously to a certain extent.So just enhance productivity, saved production cost.
Description of drawings
Fig. 1 is the utility model schematic diagram.
Embodiment
See Fig. 1, having a plurality of irregularly-shaped holes on the utility model PCB panel needs processing.The irregularly-shaped hole of positive square hole 2 for processing, inside has the circular port 1 of anti-dandruff usefulness, and strip hole 4 is similarly the irregularly-shaped hole that need process, and circular hole 3 be anti-dandruff hole, and this anti-dandruff hole and strip hole are crossing.Because the existence in anti-dandruff hole when holing to pcb board, can effectively be removed the detritus that stays because of boring, also prevent breaking of rod head simultaneously to a certain extent.And the irregularly-shaped hole of like this design also can high-qualityly process, and guarantees that it uses effect.
Claims (2)
1. the pcb board with anti-dandruff hole is characterized in that: have the anti-dandruff hole of preparing for following road irregularly-shaped hole manufacturing procedure on the above-mentioned pcb board.
2. the pcb board with anti-dandruff hole according to claim 1 is characterized in that: above-mentioned anti-dandruff hole profile can be positioned at the irregularly-shaped hole inside of needs processing, also can intersect with the irregularly-shaped hole of needs processing.
