Description
Technical field
It the utility model is related to printed substrate technical field of quality detection, and in particular to a kind of pcb board V-CUT fool proof knots
Structure.
Background technology
V-CUT is a step in printed substrate production, i.e., is dug in printed substrate and its auxiliary edges of boards intersection
Groove, to remove auxiliary edges of boards in follow-up assembly project.Typically default V-CUT row cutter tracks footpath, passes through Digit Control Machine Tool
Cutter is set to be cut along row cutter track footpath.But due to various uncertain factors be present in V-CUT processes, it is possible to create leak the circuit cut
Plate.In detection process thereafter, it is difficult to by visually identifying non-V-CUT wiring board.
Utility model content
The utility model purpose is to provide a kind of pcb board V-CUT error-proof structures, and it can efficiently solve institute in background technology
The problem of existing.
Technical problem to be solved in the utility model is realized using following technical scheme：
A kind of pcb board V-CUT error-proof structures, including technique edges and wiring board body, the technique edges and wiring board body
Intersection is provided with V-CUT paths；Technique edges or the wiring board body is provided with testing weld pad；The testing weld pad passes through one
The test lead connection of V-CUT paths both sides is weaving through, the test lead falls into unit and is also associated with two auxiliary welderings
Disk, it is described auxiliary pad be that side elevation be T-shaped pluggable pad, auxiliary pad including stretch into wiring board body pin and
The test end cap of connecting test wire, it is described test end cap between partly overlap.
By detecting the conducting situation of two testing weld pads, the wiring board without V-CUT can be filtered out.At V-CUT
After reason, above-mentioned test lead will be cut off, and two testing weld pads are off-state.When wiring board is missed V-CUT, then can monitor
It is still connected state to go out testing weld pad, should send the wiring board processing of back to V-CUT processes in time.Set auxiliary pad be in order to
Strengthen the accuracy of test effect, can be by whether being off-state between testing weld pad and auxiliary pad to judge phase during test
Answer whether one section of test lead is cut off, further refinement detection.Because auxiliary pad is arranged in wiring board body unit,
Aid in pad to be installed using plug-in, directly dismantled after test, do not influence the installation of other components.Two test end caps are set
To partly overlap, during test testing tool can one end contradict any test end cap and the other end contradicts testing weld pad and detected,
Detection is easier to be accurately positioned, and detection is also more convenient.
The testing weld pad is arranged on technique edges, and the test lead includes being arranged on what is be connected with pad on technique edges
Testing weld pad test section, roundabout section on assist side body is set, is arranged on V-CUT paths and connects roundabout section and pad
The test section of test section.
Or the testing weld pad sets assist side body, the test lead includes setting on assist side body
The pad test section that is connected with testing weld pad, roundabout section be arranged on technique edges, be arranged on V-CUT paths connect it is roundabout
Section and the test section of pad test section.
In V-CUT processes, being arranged on V-CUT test sections will be cut off.In addition, the utility model is by testing weld pad
Homonymy is arranged on, so as to the progress of convenient detection process.
Further, the line width of the test section is less than the described roundabout section line width with pad test section.
To simplify the moulding process of test lead, the line width of test lead can be improved.But test lead is wide, then it is difficult to
Thoroughly cut off in V-CUT processes, reduce testing precision.Therefore the pad test section in test lead of the present utility model and
Roundabout section of line width is larger to be made it easy to be molded, and test section line width is small and easy to cut off.
The spacing of the test section is successively decreased along testing weld pad to roundabout section of direction；Described roundabout section is the isosceles without base
It is trapezoidal.
Said structure can effectively reduce the cost for being manufactured wire.
The pad test section and roundabout section of line width are 0.25mm；The test section line width is 0.1mm.
Verified through inventor, pad test section wide 0.25mm, compared with easy-formation, is not easy to be etched liquid medicine corrosion with roundabout section
Disconnect.0.1mm test section both can guarantee that molding effect, and and can improves measuring accuracy to greatest extent.
Described roundabout section of upper bottom is away from V-CUT paths at least 0.3mm.
Said structure can prevent from, because of test lead skew and without V-CUT paths, causing test failure.
The auxiliary pad is that side elevation is T-shaped insertable pad.
The beneficial effects of the utility model are：
The utility model sets test lead and the survey at test lead both ends in PCB V-CUT paths both sides
Test weld disk, it can quickly and accurately detect the V-CUT situations of wiring board.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Fig. 2 is the structural representation that the utility model aids in pad.
Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
