Abstract
The utility model relates to a PCB (Printed Circuit Board) capable of quickly judging V-CUT. The PCB comprises a circuit board (1), technical edges (2), V-CUT lines (5), leads (3) and test points (4), wherein the circuit board (1) is provided with four corners, one lead (3) is arranged on each V-CUT line (5) of each technical edge (2) of each corner of the circuit board (1), and one test point (4) is respectively arranged on two ends of each lead. The PCB capable of quickly judging the V-CUT, disclosed by the utility model, has the advantages of cutting off the leads when the V-CUT is executed on the PCB and displaying non-conduction when current is charged to the test points of the two ends of each lead during testing. Through the wiring structure of the PCB disclosed by the utility model, anti-miss-cutting V-CUT efficiency of the circuit board is high and exact, a traditional manual visual detection process is broken through, artificial inspector loss is reduced and the detection speed and the quality yield are largely increased.
Description
Technical field
The utility model relates to the printed circuit board technology field, a kind of specifically printed circuit board that can judge the V-CUT cutting fast.
Background technology
Printed wiring board is also claimed pcb board; With the insulation board is base material, is cut into certain size, has a conductive pattern on it at least; As substrate; And be provided with hole (like installing holes such as component hole, fastener hole, metal aperture) on substrate top, and be used for replacing installing the chassis of electronic devices and components in the past, realize being electrically connected between the component pin through the conductive pattern on the substrate, pad and metallization via hole.As electronic product basically the most also is most crucial parts, and printed wiring board extensively applies on each electronic product and main equipment and the device.Printed wiring board needs to carry out the V-CUT cutting to the plate that the technology limit is arranged after processing and forming, so that plate is divided in components and parts encapsulation back, during the V-CUT cutting test lead is cut off, and when finished product test, is utilized in the p-wire two ends and powers up and flowing to the disconnected test that works.Thereby judge to have or not and leak V-CUT.The tradition artificial visual is checked easy omission disappearance, influences production efficiency and product quality.
Summary of the invention
The purpose of the utility model provides a kind of whether circuit board V-CUT is cut can be both accurate, the printed circuit board of judging fast again.
The utility model can be judged the printed circuit board of V-CUT cutting fast, comprising: lead 3 of cloth on the V-CUT line 5 on the technology limit 2 that circuit board is 1 four jiaos, and respectively lay a test point 4 at the lead two ends.
The width of lead 3 is 0.1 millimeter, and length is 10 millimeters.
When the printed circuit board of judgement V-CUT cutting is achieved in that moulding V-CUT fast; The V-CUT cutter cuts along the V-CUT line; Perpendicular test lead is cut off, and the electric current of when finished product test, on the test point at lead two ends, annotating reaches the purpose whether inspection leaks V-CUT.
The utility model can judge fast that the advantage of the printed circuit board of V-CUT cutting is: during to printed circuit board V-CUT the lead cutting is broken off, show not conducting when on the test point at two ends, adding electric current during test.Adopt this wire structures for circuit board leakproof to cut V-CUT efficient high, accurately, broken traditionally with the artificial technology that is visually inspection, reduced artificial inspector's leakage, improved detection speed and quality yield greatly.
Description of drawings
Fig. 1 is the structural representation that can judge the printed circuit board of V-CUT cutting fast.
Embodiment
A kind of printed circuit board that can judge V-CUT cutting fast comprises: lead 3 of cloth on the V-CUT line 5 on the technology limit 2 that circuit board is 1 four jiaos, and respectively lay a test point 4 at the lead two ends.
The width of lead 3 is 0.1 millimeter, and length is 10 millimeters.
When the printed circuit board of judgement V-CUT cutting is achieved in that moulding V-CUT fast; The V-CUT cutter cuts along the V-CUT line; Perpendicular test lead is cut off, and the electric current of when finished product test, on the test point at lead two ends, annotating reaches the purpose whether inspection leaks V-CUT.
Claims (2)
