Description
Technical field
The utility model relates to circuit board processing technique field, particularly relates to a kind of circuit board prebored hole structure.
Background technology
PCB(Printed Circuit Board), Chinese is printed circuit board, and also known as printed circuit board (PCB), printed substrate, being important electronic unit, is the supporter of electronic devices and components, is the supplier of electronic devices and components electrical connection.
In printed circuit is produced, need to carry out holing etc. manufacturing procedure to pcb board.The common method of holing on circuit boards has numerical controlled machinery boring method and method for drilling holes etc., and present stage uses at most with mechanical drilling method.Along with popularizing of high density Layer increasing method wiring board, to the increase in demand of blind hole, laser drilling method application has the impetus of increase.But the reasons such as laser drill processing is poor to machined material adaptability, equipment cost is high and hole wall quality is lower, make the PCB aperture of at present nearly 90% be realized by mechanical drilling machine.
Along with conductive layer, the thickness of slab slimming of pcb board, conductive pattern miniaturization, brings electronic equipment densification, high performance.In the face of these high-end electronic products, precision and the stability requirement of PCB boring are also more and more higher, and traditional Drilling operation easily produces burr burr, and the larger Kong Shiyi of hole diameter produces the problems such as breaking.
Summary of the invention
Based on this, be necessary for the problems referred to above, provide one can avoid producing burr burr during Drilling operation, improve the circuit board prebored hole structure of circuit board processing yields.
A kind of circuit board prebored hole structure, comprise circular hole region to be drilled, offer multiple prebored hole in described circular hole region to be drilled, described prebored hole is all inscribed within described circular hole region to be drilled, and often adjacent two prebored holes are mutually tangent, and multiple prebored hole is enclosed to cover and formed feed district.
Preferably, described prebored hole is 3, and prebored hole is tangent mutually, and is all inscribed within described circular hole region to be drilled.
Preferably, described prebored hole is 4, is symmetricly set in described circular hole region to be drilled.
Preferably, described circular hole regional diameter to be drilled is not less than 4 ㎜.
Foregoing circuit plate prebored hole structure, owing to being provided with prebored hole, define engraved structure in circular hole region to be drilled, carry out brill circular hole add man-hour to circular hole region to be drilled, cutter can fall into circular hole region to be drilled from feed district center, due to this region hollow out, so Tool in Cutting removes surplus can complete boring, boring cutting output is few, and working (machining) efficiency is high, and not easily produce burr burr, and cutter is not easily caused to fracture.
Accompanying drawing explanation
Fig. 1 is the structural representation of circuit board prebored hole structure in an execution mode;
Fig. 2 is the structural representation of circuit board prebored hole structure in another execution mode.
Embodiment
For the ease of understanding the utility model, below with reference to relevant drawings, the utility model is described more fully.Preferred embodiment of the present utility model is given in accompanying drawing.But the utility model can realize in many different forms, is not limited to embodiment described herein.On the contrary, provide the object of these embodiments be make the understanding of disclosure of the present utility model more comprehensively thorough.
As shown in Figure 1 or 2, a kind of circuit board prebored hole structure, comprise circular hole region 100 to be drilled, multiple prebored hole 110 is offered in described circular hole region 100 to be drilled, described prebored hole 110 is all inscribed within described circular hole region 100 to be drilled, and often adjacent two prebored holes 110 are mutually tangent, multiple prebored hole 110 is enclosed to cover and is formed feed district 120.
Circular hole region 100 to be drilled refers to the region needing to bore circular hole.The prebored hole 110 of inscribe is set in described circular hole region 100 to be drilled, in circular hole region 100 to be drilled, defines engraved structure.And this engraved structure periphery is inscribed within circular hole region 100 to be drilled, and center remains the bearing area that Drilling operation needs, i.e. feed district 120.Brill circular hole is carried out to circular hole region 100 to be drilled and adds man-hour, cutter can fall into circular hole region 100 to be drilled from center, feed district 120, due to this region hollow out, so Tool in Cutting removes surplus can complete boring, boring cutting output is few, working (machining) efficiency is high, and not easily produces burr burr, and not easily causes cutter to fracture.
As shown in Figure 1, wherein in an embodiment, described prebored hole 110 is 3, and prebored hole 110 is tangent mutually, and is all inscribed within described circular hole region 100 to be drilled.In this embodiment, prebored hole 110 quantity is few, is easy to processing.
As shown in Figure 2, in another embodiment, described prebored hole 110 also can be 4, is symmetricly set in described circular hole region 100 to be drilled.Every two adjacent prebored holes 110 are tangent, and are all inscribed within circular hole region 100 to be drilled.In this embodiment, void region is large, and during Drilling operation, cutting output is few, is easy to improve Drilling operation efficiency.
Described circular hole region 100 to be drilled diameter is not less than 4 ㎜.When Circularhole diameter to be drilled is less than 4 ㎜, directly carry out bore operation also can, along with aperture increases, 3,4 or more prebored holes 110 can be set as required, to reduce boring cutting output, improve Drilling operation yields and working (machining) efficiency.
The above embodiment only have expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
