Abstract
The invention discloses a PCB (printed circuit board) numerical-control drilling method. For each PCB inner hole diameter, two holes are formed in the peripheral edge of a PCB according to hole diameter, and one of the two holes is arranged to be a head hole which is drilled firstly while the other one is arranged to be a tail hole which is drilled lastly; the head hole, a PCB inner hole and the tail hole are processed sequentially. After the PCB is drilled, operating personnel can find whether knife breaking or drilling missing occurs or not in the process when the PCB is machined by only checking the head hole and the tail hole, and can acquire knife breaking and drilling missing information timely, so that knife breaking and drilling missing during machining of the PCB can be prevented well, and producing of defective products is avoided.
Description
Technical field
The present invention relates to pcb board and make field, particularly a kind of PCB numerical control drilling processing method.
Background technology
PCB numerical control drilling is an important procedure in pcb board manufacturing process, PCB numerical control drilling is got out after referring to and being optimized by the aperture that client needs by the processing formula of engineering design by drill in printed board, after drill wearing and tearing acquire a certain degree, there will be breaking and cause leaking the situation appearance of boring, if by customer requirement by the production plate shipment of having bored to client time, PCBA(Printed Circuit Board+Assembly can be made, refer to PCB hollow plate part on SMT, again through the whole process of DIP plug-in unit) cannot be installed on product smoothly, thus cause PCBA to scrap.In current industry, leakage is bored and control general operation in the following way: 1, install break detection device additional from device hardware aspect; 2, check that outward appearance prevents problem board from flowing out by manual method.And adopt first method, breaking measuring ability can be lost efficacy along with the aging of equipment and produce Lou to bore, also can produce certain maintenance cost simultaneously; Adopt second method, testing staff can produce visual fatigue can not ensure that problem board is all detected, and thus thoroughly can not stop problem board.
Therefore, prior art has yet to be improved and developed.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of PCB numerical control drilling processing method, is intended to solve existing PCB numerical control drilling technology and often occurs that breaking leaks the problem of boring and cannot detect problem board in time.
In order to realize the object solved the problems of the technologies described above, present invention employs following technical scheme:
A kind of PCB numerical control drilling processing method of the present invention, namely pore size is pressed in the hole in pcb board and distinguish, identical hole, aperture is same group of hole; For often organizing identical hole, aperture, respectively add two holes respectively in pcb board periphery sides, one of them is set to first hole got out, hole headed by this hole, and another is set to last hole got out, and this hole is uropore; Hole, pcb board endoporus, uropore headed by processing sequence.
By checking through each group of first hole of the pcb board of bore process and uropore, judge that this pcb board is by boring procedure, whether PCB numerical control drilling breaking occurs or leaks is bored; If the first hole drill in the first hole of at least one group and uropore goes out and uropore does not get out, then illustrate that numerical control drilling there occurs breaking or leaks in the process of holing to this pcb board and bore; If first hole of certain group and uropore all do not get out, then illustrate numerical control drilling before to the boring of this pcb board and this breaking or boring be occur to leak to this group hole to bore; If first hole and the uropore of each group all get out, then illustrating must by boring via hole at this pcb board, and numerical control drilling breaking does not occur or leaks to bore.
Like this, operating personnel only need to check that first hole and uropore just can find whether pcb board occurs breaking or leak boring phenomenon in process, thus allow operator obtain breaking leakage brill information in time, brill phenomenon is leaked to the breaking of pcb board in process and has good foolproof function, stopped the outflow of defective products.
By adopting technique scheme, the present invention has following beneficial effect:
1, a kind of PCB numerical control drilling processing method of the present invention has method simply, saves parts, reduces the advantage of production cost;
2, the present invention is by respectively adding two holes respectively in pcb board periphery sides pressing board internal orifice dimension size, and sets the method for the processed order in each hole; First hole and uropore just can be very easy to find pcb board by boring procedure to make operating personnel only need to check, numerical control drilling whether breaking or leak bores, thus allowing operating personnel obtain breaking information in time, this leaks breaking and is drilled with certain foolproof function, has stopped the outflow of defective products.
Detailed description of the invention
Below in conjunction with embodiment, further explanation is explained to this patent.But the protection domain of this patent is not limited to concrete embodiment.
Embodiment 1
A kind of PCB numerical control drilling processing method of this patent, namely pore size is pressed in the hole in pcb board and distinguish, identical hole, aperture is same group of hole; For often organizing identical hole, aperture, respectively add two holes respectively in pcb board periphery sides, one of them is set to first hole got out, hole headed by this hole, and another is set to last hole got out, and this hole is uropore; Hole headed by processing sequence, pcb board endoporus, uropore;
By checking through each group of first hole of the pcb board of bore process and uropore, judge that this pcb board is by boring procedure, whether PCB numerical control drilling breaking occurs or leaks is bored; If the first hole drill in the first hole of at least one group and uropore goes out and uropore does not get out, then illustrate that numerical control drilling there occurs breaking or leaks in the process of holing to this pcb board and bore; If first hole of certain group and uropore all do not get out, then illustrate numerical control drilling before to the boring of this pcb board and this breaking or boring be occur to leak to this group hole to bore; If first hole and the uropore of each group all get out, then illustrating must by boring via hole at this pcb board, and numerical control drilling breaking does not occur or leaks to bore.
Like this, operating personnel only need to check that first hole and uropore just can find whether pcb board occurs breaking or leak boring phenomenon in process, thus allow operator obtain breaking leakage brill information in time, brill phenomenon is leaked to the breaking of pcb board in process and has good foolproof function, stopped the outflow of defective products.
