CN201499373U - PCB board capable of preventing V-CUT operation deviation - Google Patents

Abstract

The utility model relates to a PCB board, in particular to a welding disc structure thereof. The utility model aims at providing a PCB board capable of preventing V-CUT operation deviation, which has the advantages of low cost and high reliability. The PCB board capable of preventing V-CUT operation deviation comprises a conducting wire strip which needs V-CUT operation, wherein a part of the conducting wire strip needing the V-CUT operation is provided with a position marking line. The utility model has the advantages that the V-CUT operation of the PCB board only needs to be carried out along the V-CUT position marking line, the deviation is not easy to occur in the V-CUT operation, in addition, the deviation can be easily found in the subsequent visual check in case of occurrence, and the deviation can be corrected in time.

Description

Can prevent the pcb board of V-CUT operation off normal

Technical field

The utility model relates to pcb board, relates to its conductor structure 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.

Usually need carry out the V-CUT operation to auxiliary edges of boards in the course of processing of existing pcb board, promptly carry out grooving work so that the client can get rid of edges of boards easily behind the intact auxiliary edges of boards of follow-up assemble flow utilization according to customer requirement.But pcb board V-CUT operating process often easily operation wander off, has a strong impact on the outward appearance of pcb board, even can not use, and the operation back visual means that wanders off also is not easy to judge.

The utility model content

The purpose of this utility model provide a kind of with low cost, can prevent the pcb board of V-CUT operation off normal reliably.

The technical scheme that realizes the utility model purpose is as follows:

A kind of pcb board of preventing V-CUT operation off normal has the lead bar that need carry out the V-CUT operation, needs to carry out V-CUT operation place on the above-mentioned lead bar and is provided with the location mark line.

As long as carry out along V-CUT location mark line, the V-CUT operation just was not easy off normal when this novel advantage was pcb board V-CUT operation, and just in case the off normal situation takes place, also found easily in follow-up visual examination, was corrected timely.

Description of drawings

Fig. 1 is the utility model schematic diagram.

Embodiment

See Fig. 1, need to carry out to need to carry out V-CUT operation place on the lead bar 1 of V-CUT operation on the utility model pcb board and be provided with location mark line 2.When carrying out the V-CUT operation, as long as carry out along V-CUT location mark line, the V-CUT operation just is not easy off normal.

Claims (1)

1. the pcb board that can prevent V-CUT operation off normal has the lead bar (1) that need carry out the V-CUT operation, it is characterized in that: need to carry out V-CUT operation place on the above-mentioned lead bar and be provided with location mark line (2).
