Abstract

The utility model relates to a PCB board, in particular to the bonding pad structure of the PCB board, and aims at providing the PCB board with low cost and reliable V-CUT operation omitting prevention. In the PCB board with V-CUT operation omitting prevention, a testing strip is designed on a position needing the V-CUT operation, and both ends of the testing strip are provided with testing discs which are distributed at two sides of a V-CUT line. The testing strip is composed of the testing discs at two ends and a line in the middle. For a PCB board needing the V-CUT operation, the omitting prevention testing strips are arranged at two sides of the V-CUT line; when an electrical test is performed for the subsequent working procedure of the V-CUT operation, a conduction test is only needed for the testing discs, if conduction is tested, the V-CUT operation is judged to be omitted, thereby the working efficiency is greatly improved, and the V-CUT operation is ensured not to be omitted.

Description

But the pcb board of leakproof V-CUT operation

Technical field

The utility model relates to pcb board, relates to its pad 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 the employee tends to forget the V-CUT operation in pcb board manufacturing process, and detect in after this testing process because by artificial visual, judging has the quite bothersome effort of the work of not carrying out the V-CUT operation, even has V-CUT operation and the situation generation that do not obtain remedying in the detection of back with Louing.

The utility model content

But the purpose of this utility model provides a kind of pcb board of leakproof V-CUT operation with low cost, reliable.

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

But the pcb board of a kind of leakproof V-CUT has the test-strips that need carry out the V-CUT operation.Above-mentioned test-strips couples together the circular test panel of mutual conducting by lead and forms.Owing to there is test-strips to be distributed in the both sides that to carry out the V-CUT line, when carrying out leakproof V-CUT when detecting, only need do continuity test, if conducting then can conclude to leak and do the V-CUT operation to above-mentioned test-strips, this will increase work efficiency greatly, guarantee that the V-CUT operation can not omitted.

Description of drawings

Fig. 1 is the utility model schematic diagram.

Embodiment

See Fig. 1, the both sides that need to carry out the welding bar 1 of V-CUT operation on the utility model pcb board are provided with leakproof V-CUT test-strips 2.When the leakproof of carrying out V-CUT operation detects, only need between the test panel of test test-strips both sides whether conducting, if conducting then illustrate that this place leaks and done the V-CUT operation, otherwise then explanation not leakage do not do.So improved the operating efficiency that leakproof V-CUT detects greatly, and prevented that the omission incident that the artificial visually examine may cause from taking place.

Claims

1, but a kind of pcb board of leakproof V-CUT operation has the welding bar (1) that need carry out the V-CUT operation, and it is characterized in that: above-mentioned welding bar both sides are provided with test-strips (2).

But 2, the pcb board of leakproof V-CUT operation according to claim 1, it is characterized in that: above-mentioned test-strips is made up of the circular test panel of mutual conducting.
