Abstract
The invention relates to the technical field of production of circuit boards, in particular to a method for fabricating a connected slot in a PCB. According to the method, the area of a to-be-cut plate when two end parts of a long slot are drilled is relatively small by arranging lead holes arranged in long slot positions; and the influence due to the fact a drill bit suddenly loses a support point when walking to a round hole can be reduced, so that the problem that the drill bit slips is solved; the influence due to the fact a large-area plate suddenly appears when the drill bit walks to the other end of the long slot from the round hole is reduced; and the problem that the connected slot is relatively short can be solved by arranging the lead holes. A process of drilling burr holes is added after the long slot is drilled; and burrs carried by the drill bit at the intersected part of the edge of the round hole and the long slot can be removed, so that orifice burrs formed after copper deposition and full-plate plating in later procedures are avoided. The connected slot is fabricated by the drilling process disclosed by the invention, so that the problems of relatively short connected slot and existence of orifice burrs can be solved.
Description
Technical field
The present invention relates to board production technical field, particularly relate to a kind of method of the company's of making hole slot on PCB.
Background technology
PCB (PrintedCircuitBoard), Chinese is printed circuit board, and also known as printed substrate, being important electronic unit, is the supporter of electronic devices and components, is the carrier of electronic devices and components electrical connection.According to the Functional Design of PCB, various hole need be made to meet different functional requirements on PCB, as buried via hole, blind hole, through hole and other irregularly-shaped hole.Connect hole slot and be one in irregularly-shaped hole, connect hole slot and refer to and to be superimposed the slotted eye formed by circular hole and elongated slot, namely company's hole slot is as shown in Figure 1 superimposed by circular hole A and elongated slot B and is formed.Prior art is generally subdrilling circular hole when the company's of making hole slot, and then bore elongated slot, but due to the strong point can be lost suddenly when boring and chew the intersection going to elongated slot and circular hole, brill is chewed and therefore be there will be slight slip, thus the length of bored elongated slot can be caused shorter than the length of design, namely can cause the problem that flute length is partially short.In addition, because the intersection of elongated slot and circular hole is without the strong point, bores to chew to bore when going to intersection and chew and can take burr out of with its direction of rotation, through after can form aperture burr after the heavy copper of operation and electric plating of whole board process.Therefore, existingly connect the manufacture method of hole slot product can be made to exist the quality hidden danger that there is burr in the partially short and aperture of flute length, have a strong impact on quality and the production efficiency of product.
Summary of the invention
The present invention is directed to the existing problem connecting the manufacture method of hole slot and easily cause the partially short and aperture burr of flute length, a kind of manufacture method improving company's hole slot of the partially short and aperture burr problem of flute length is provided.
For achieving the above object, the present invention by the following technical solutions.
The company's of making method of hole slot on PCB, the described hole slot that connects is by producing circular hole that plate is superimposed and elongated slot is formed, and the described manufacture method connecting hole slot comprises the following steps:
S1 drill hole: described production plate is designed with circular hole position and elongated slot position, described circular hole position is the position need boring circular hole, the shape of circular hole position and circular hole and measure-alike, and described elongated slot position is the position need boring elongated slot, the shape of elongated slot position and elongated slot and measure-alike; Described elongated slot position two ends and be positioned at elongated slot position and bore one respectively and circular draw hole, described in draw hole aperture be less than the groove width of elongated slot position.
Preferably, the end of described elongated slot position is curved, described in draw the end of hole and elongated slot position tangent.
Preferably, the aperture 0.1mm less of the groove width of elongated slot position in hole is drawn described in.
S2 bores circular hole: on circular hole position, bore circular hole.
S3 bores elongated slot: on elongated slot position, bore elongated slot.
Preferably, also comprise step S4 after step S3 and bore burr hole: be positioned at circular hole internal drilling at circular hole edge and elongated slot intersection, the hole of boring is called burr hole, described burr hole and circular hole tangent.
Compared with prior art, the invention has the beneficial effects as follows: the present invention draws hole by arranging in elongated slot position, make the area of the sheet material of the required cutting when boring the both ends of elongated slot less, can reduce to bore the impact of chewing and to lose suddenly the strong point when going to circular hole place and causing, improve the problem of boring and chewing skidding with this; And reduce to occur that suddenly large area sheet material stops the impact caused when the other end being gone to elongated slot by circular hole chewed by brill; Thus draw hole and can improve by arranging and connect the partially short problem of hole slot flute length.Bore to increase after elongated slot and bore burr hole flow process, can remove to bore and chew the burr taken out of at circular hole edge and elongated slot intersection, thus avoid through after operation sink after copper and electric plating of whole board and form aperture burr.Made by boring flow process of the present invention and connect hole slot, the flute length connecting hole slot can be improved partially short and there is the problem of aperture burr.
Accompanying drawing explanation
Fig. 1 is the structural representation of the company's hole slot formed of being superimposed by circular hole A and elongated slot B;
Fig. 2 is the structural representation connecting hole slot in embodiment;
The porose schematic diagram be superimposed that Fig. 3 bores in the course of processing by the company's hole slot in embodiment.
Embodiment
In order to understand technology contents of the present invention more fully, below in conjunction with specific embodiment, technical scheme of the present invention being described further and being illustrated.
Embodiment
The present embodiment provide a kind of on PCB the company's of making method of hole slot, the company's of making hole slot on the production plate specifically formed in the pressing working procedure in PCB production procedure, described company's hole slot as shown in Figure 2, is made up of the circular hole be superimposed and elongated slot.In actual production, after the company's of making hole slot, the follow-up flow process through producing PCB is also needed to produce the PCB finished product having and connect hole slot.
