Abstract
The utility model discloses a V-cut foolproof circuit board, which comprises a technical edge and a circuit board body. The circuit board is characterized in that a V-cut path is arranged at the junction part of the technical edge and the circuit board body; test pads are arranged on the technical edge or the circuit board body; and the test pads are connected by a test wire passing across two sides of the V-cut path tortuously. Through arrangement of the test wire on the two sides of the V-cut path of the circuit board and the test pads on two ends of the test wire, V-cut situation of the circuit board can be tested quickly and precisely.
Description
Technical field
The utility model relates to printed substrate technical field of quality detection, is specifically related to a kind of V-CUT fool proof wiring board.
Background technology
V-CUT is a step during printed substrate is produced, in printed substrate and the grooving of auxiliary edges of boards intersection thereof, to will assist edges of boards to remove in follow-up assembly project.The normally default capable cutter track of V-CUT footpath, makes cutter follow cutter track footpath by Digit Control Machine Tool and cuts.But owing to there being various uncertain factors in V-CUT operation, may produce the wiring board of Lou cutting.In detection operation after this, be difficult to by visual, the wiring board of V-CUT not be identified.
Summary of the invention
In view of this, the utility model discloses the wiring board that a kind of energy is accurate, Quick Measuring is made omission V-CUT processing.
The purpose of this utility model is achieved through the following technical solutions: a kind of V-CUT fool proof wiring board, comprise technique edges and wiring board body, and it is characterized in that: described technique edges and wiring board body intersection are provided with V-CUT path; Described technique edges or wiring board body are provided with testing weld pad; Described testing weld pad connects by a roundabout test lead through both sides, V-CUT path.
By detecting the conducting situation of two testing weld pads, can filter out the wiring board without V-CUT.After V-CUT processes, above-mentioned test lead will be cut off, and two testing weld pads are off-state.When wiring board is missed V-CUT, can monitor out testing weld pad is still connected state, should in time this wiring board be sent back to V-CUT operation and process.
Described testing weld pad is arranged on technique edges, and described test lead comprises and is arranged on the testing weld pad test section that is connected with pad on technique edges, is arranged on wiring board body roundabout section, is arranged on and on V-CUT path, connects the roundabout section of test section with pad test section.
Or, described testing weld pad is arranged on wiring board body, and described test lead comprises and is arranged on the pad test section that is connected with testing weld pad on wiring board body, is arranged on technique edges roundabout section, is arranged on and on V-CUT path, connects the roundabout section of test section with pad test section.
In V-CUT operation, being arranged on V-CUT test section will be cut off.In addition, the utility model is arranged on homonymy by testing weld pad, thus convenient the carrying out that detects operation.
Further, described test section live width be less than described roundabout section of live width with pad test section.
For simplifying the moulding process of test lead, can improve the live width of test lead.But test lead is wide, be difficult to thoroughly be cut off in V-CUT operation, reduce testing precision.Therefore pad test section and the roundabout section of live width in test lead of the present utility model makes it to be more greatly easy to moulding, and test section live width is compared with little and be easy to cut off.
The spacing of described test section is successively decreased to roundabout section of direction along testing weld pad; Described roundabout section is isosceles trapezoid without base.
Said structure can effectively reduce the cost of manufacturing shaped conductors.
The live width of described pad test section and roundabout section is 0.25mm; Described test section live width is 0.1mm.
Through inventor checking, the pad test section that 0.25mm is wide compared with easy-formation, is difficult for etched liquid medicine corrosion disconnection with roundabout section.The test section of 0.1mm can guarantee molding effect, can improve to greatest extent measuring accuracy again.
The upper base of described roundabout section is 0.3mm at least apart from V-CUT path.
Said structure can prevent from not passing through V-CUT path because of test lead skew, causes test failure.
The utility model arranges test lead and in the testing weld pad at test lead two ends, quickly and accurately the V-CUT situation of detection line plate in the both sides, V-CUT path of PCB.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
For the ease of it will be appreciated by those skilled in the art that below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:
Embodiment 1
The present embodiment provides a kind of V-CUT fool proof wiring board, comprises technique edges 2 and wiring board body 1, it is characterized in that: described technique edges 2 is provided with V-CUT path 3 with wiring board body 1 intersection; Described technique edges or wiring board body are provided with testing weld pad 4; Described testing weld pad 4 connects by a roundabout test lead through 3 both sides, V-CUT path.
By detecting the conducting situation of two testing weld pads, can filter out the wiring board without V-CUT.After V-CUT processes, above-mentioned test lead will be cut off, and two testing weld pads are off-state.When wiring board is missed V-CUT, can monitor out testing weld pad is still connected state, should in time this wiring board be sent back to V-CUT operation and process.
Described testing weld pad 4 is arranged on technique edges 2, and described test lead comprises and is arranged on the pad test section 51 that is connected with testing weld pad 4 on technique edges 2, is arranged on wiring board body 1 roundabout section 52, is arranged on and on V-CUT path, connects roundabout section 52 test section 53 with pad test section 51.
In V-CUT operation, being arranged on V-CUT test section 53 will be cut off.In addition, the utility model is arranged on testing weld pad 4 on technique edges 2, thus convenient the carrying out that detects operation.
The spacing of described test section is successively decreased to roundabout section of direction along testing weld pad; Described roundabout section is isosceles trapezoid without base.
Described pad test section 51 is 0.25mm with the live width of roundabout section 52; Described test section 53 live widths are 0.1mm.
