Abstract
The PCB dual surface drilling positioning has at least four positioning holes on the board, positioning pins on the drilling fixture or drilling platform opposite to the positioning holes, with the positioning pins and the holes matching with each other to fix the PCB board when it drills from either positive or negative side of the board.It can use the interference principle of positioning, reduce the deviation of two positioning zero points, with high positioning precision, and increased in drilling efficiency and yield rate.
Description
Technical field
The present invention relates to a kind of pcb board boring method, refer in particular to a kind of pcb board double-face drilling and positioning method.
Background technology
Positive and negative boring is meant that plate is thicker and can't once drills or once drill the processing technology that the tow sides of being taked when quality can't guarantee drill through the hole.Generally be used for the range of work at the aperture of aperture D≤1.0mm, and wherein most apertures are between 0.6～0.8mm.Adopt this boring method to add man-hour, when the radius-thickness ratio of plate bigger, if then easily form " 8 " word hole when the same diameter drill bit is used in two sides boring, for head it off, at present usually a kind of method that adopts is that to increase the diameter of tow sides boring poor, but because plate is thicker, be increased to a certain degree after, the easy breaking of rod of drill bit can't solve effectively this problem; And, when the different-diameter drill bit is used in the boring of positive and negative two sides,, cause the center, hole stepped hole to occur owing to when holing from positive and negative respectively, be easy to generate the situation that do not overlap the zero point of twice location, influence the quality of product.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of pcb board double-face drilling and positioning method, its positioning accuracy height.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of pcb board double-face drilling and positioning method, it is provided with at least 4 locating holes on pcb board, and on boring grab or rig floor, be provided with shop bolt correspondingly with described locating hole, from the pcb board front and reverse side when holing, described shop bolt and locating hole be corresponding matching and locate pcb board one by one respectively.
The invention has the beneficial effects as follows: by at least 4 locating holes are set on circuit board, and the corresponding shop bolt that on boring grab or rig floor, is provided with correspondingly, utilized the interference principle between the location, reduce the deviation of locating zero point for twice, the positioning accuracy height, and then effectively promoted the boring passing rate of processing.
Description of drawings
Fig. 1 is the locating hole schematic diagram of an embodiment of pcb board double-face drilling and positioning method of the present invention.
Fig. 2 is the locating hole schematic diagram of another embodiment of pcb board double-face drilling and positioning method of the present invention.
Below in conjunction with accompanying drawing the present invention is described further:
The specific embodiment
As shown in Figure 1, the invention provides a kind of pcb board double-face drilling and positioning method, it is by being provided with at least 4 locating holes 10 on pcb board 1, and be provided with shop bolt correspondingly at boring grab and described locating hole, respectively from the pcb board front and reverse side when holing, by described shop bolt and locating hole corresponding matching and locate pcb board one by one.Described locating hole is symmetrically distributed.According to the size of pcb board, described locating hole quantity generally is provided with 4～16, is preferably 4～6.Among the embodiment as shown in Figure 1, the locating hole on the circuit board is provided with 4 symmetrically; And in another embodiment shown in Figure 2, circuit board is provided with 6 symmetrically arranged locating holes.
The present invention cooperates by locating hole and shop bolt, and compare with existing locate mode, increased the quantity of locating hole, it is when front boring and reverse side boring, when corresponding matching is located one by one by shop bolt and locating hole, can increase the hole count of location, utilize the interference principle between the location, reduce the deviation of locating zero point for twice; Reduce the fit clearance of each location as far as possible, cooperate again and adopt the better rigidity drill bit, thereby can improve positioning accuracy and boring qualification rate effectively.
This method does not increase Material Cost because the not variation of the tolerance of aperture and shop bolt is therefore easy to operate in actual production process.Be not subjected to the restriction of drill bit design bottleneck.
Claims (3)
