Abstract
Utilize the module of detectable shaping locating bias provided by the utility model, when carrying out processing and forming to pcb board, after plate is fixed with pin, with gong knife along without gong square groove on copper region unit, the intact condition in square groove surrounding NPTH holes is examined by visual observation, you can is quickly judged offset direction and offset and is improved.
Description
Technical field
It the utility model is related to wiring board manufacturing field, more particularly to a kind of module of detectable shaping locating bias.
Background technology
It is that wiring board is fixed using pin nail mode in assist side production process, in moulding process, every 3
Pin fixes a PCS, and during actual job, because manual pin is followed closely, locating bias often occurs, goes out initial workpiece in gong
Shi Caineng is had found, and offset can not be intuitively determined from the initial workpiece that gong goes out, and just can determine that after need are measured, time-consuming to take
Power.
Utility model content
Judge for convenience of quickly skew is followed closely to pin, the utility model provides a kind of detectable shaping locating bias
Module, including pcb board, the pcb board is square, and first to fourth test block is arranged with the copper sheet of pcb board edges of boards, is amounted to
Four test blocks；The test block include square without copper region unit and it is multiple surround without copper region unit set NPTH holes,
The hole center in NPTH holes is identical with the distance correspondingly without copper region block edge in same test block；In first to fourth test block
The hole center in NPTH holes increases successively with the distance of corresponding no copper region block edge.
Preferably, two NPTH holes are correspondingly provided with each edge of the no copper region unit.
Further, the hole centre-to-centre spacing in two NPTH holes on the same side without copper region unit is 2mm.
Preferably, a diameter of 0.5 ~ 0.8mm in NPTH holes.
Preferably, the size of the no copper region unit is 4*4 mm.
Preferably, in first to fourth test block hole center in NPTH holes and corresponding no copper region block edge distance
It is followed successively by 0.05mm, 0.075mm, 0.1mm, 0.125mm.
Preferably, first to fourth test block is located at the diagonal positions of pcb board edges of boards.
Using it is provided by the utility model it is detectable shaping locating bias module, to pcb board carry out processing and forming when,
After plate is fixed with pin, square groove surrounding NPTH holes are examined by visual observation without gong square groove on copper region unit along module with gong knife
Intact condition, you can quickly judge that offset direction and offset are simultaneously improved.
Brief description of the drawings
Fig. 1 is the module embodiments structural representation of detectable shaping locating bias provided by the utility model.
Embodiment
Understand technology contents of the present utility model for convenience of those skilled in the art, below in conjunction with the accompanying drawings and embodiment pair
The utility model is described in further detail.
The module of detectable shaping locating bias as shown in Figure 1, including square pcb board 9, on the copper sheet of pcb board edges of boards
The first test block 1, the test block 3 of the second test block 2 the 3rd, the 4th test block 4 are arranged with, each test block includes square
4*4 mm surround the NPTH holes B set without copper region unit without copper region unit A and 8, are correspondingly set in no copper region unit A each edge
There are two NPTH holes B.The hole centre-to-centre spacing in the adjacent NPTH holes in same test block is 2mm, a diameter of 0.6mm in NPTH holes
The hole center in NPTH holes is identical with the distance correspondingly without copper region block edge in same test block；First to fourth surveys
The hole center in NPTH holes increases successively with the distance of corresponding no copper region block edge in test block, be followed successively by 0.05mm, 0.075mm,
0.1mm、0.125mm。
To pcb board carry out processing and forming when, after wiring board to be formed is fixed with pin, with gong knife along module without
Gong square groove on copper region unit, then the intact condition in sight check square groove surrounding NPTH holes, you can quickly judge offset direction and
Offset is simultaneously improved.
The NPTH holes on such as four test block peripheries then can determine that offset within 0.05mm without breakage；If there is NPTH
Hole is damaged, then can be by judging damaged NPTH holes and the accordingly relative position judgement offset direction without copper region unit, and can be direct
By the most slight NPTH holes of damaged degree with accordingly without the distance between copper region unit value come auxiliary judgement offset, very soon
Speed is convenient.
It is specific implementation of the present utility model above, its description is more specific and detailed, but can not therefore manage
Solve as the limitation to the utility model patent scope.It should be pointed out that for the person of ordinary skill of the art, not
On the premise of departing from the utility model design, various modifications and improvements can be made, these obvious alternative forms are equal
Belong to the scope of protection of the utility model.
