Abstract
The invention relates to the field of processing a printed circuit board and specifically relates to a forming processing hole for the printed circuit board for correcting a compensation factor. The forming processing hole is a slot hole and is formed at the edge of the printed circuit board; the forming processing hole is shaped as a concave groove; and two angular positions at the bottom of the forming processing hole extend toward two sides, thereby forming an arc-shaped groove. The forming processing hole for the printed circuit board has the beneficial effects that a milling cutter with the cutter diameter being 2.0mm is utilized to compensate the traditional forming processing slot hole for 0.1mm, and the milling cutter with the cutter diameter being 2.0mm is used for processing and producing the forming processing hole for the printed circuit board with convenience in USP slotting, increased production quality of the printed circuit board and forming operating efficiency (being increased by 17.3%).
Description
Technical field
What the present invention relates to is the printed circuit board (PCB) manufacture field, and what be specifically related to is a kind of printed circuit board forming machining hole of correcting penalty coefficient.
Background technology
Along with development of integrated circuits,, also be to develop wherein to higher wiring density, better electrical property and hot property direction to the also requirement that encapsulates the printed circuit board (PCB) (pcb board) that uses to the also raising thereupon of requirement of integrated circuit encapsulation.For reaching above-mentioned requirements, technology such as exploitation high reliability via, processing and forming hole are crucial, and it all has very big influence to the density of wiring and the efficient of encapsulation back electricity, hot property and processing.
In the PCB manufacture process, PCB external form moulding processing is the manufacturing procedure that belongs to back segment, at this moment; Pcb board internal wiring operation is mostly accomplished, so, if this stage can't meet the demands; Make that not only qualification rate declines to a great extent, the cost of spoiled goods of generation will also be the highest.And in the existing pcb board design; The offset of external form moulding machining hole is too small; Make the draw-in groove hole less than normal, need make Bu Chang ﹐ compensation size to this position through affirmation is that 0.1mm Zuo You ﹐ so the present invention increase compensation 0.1mm on the basis in existing processing and forming draw-in groove hole.Draw-in groove of the present invention hole is adding man-hour; By make-up machine chuck gripping 2.0mm milling cutter; Make two jiaos of positions, bottom, draw-in groove hole extend to form Baltimore groove, process so that the quality of production and the operations for forming efficient of USP slot, raising printed circuit board (PCB) through this compensation to both sides.
Summary of the invention
In view of the deficiency that exists on the prior art, the object of the present invention is to provide a kind of USP of being convenient to jack, the quality of production that improves printed circuit board (PCB) and the printed circuit board forming machining hole of operations for forming efficient.
To achieve these goals, the technical scheme that the present invention adopted is: the printed circuit board forming machining hole is characterized in that: described processing and forming hole is the draw-in groove hole; The processing and forming hole is Baltimore groove, extends to form arc groove in two jiaos of positions, bottom, processing and forming hole to both sides.
Aforesaid printed circuit board forming machining hole, printed circuit board edge is located in described processing and forming hole.
Aforesaid printed circuit board forming machining hole is characterized in that: described arc groove is compensated for as 0.1mm.
Printed circuit board (PCB) of the present invention is formed by stacking four layers of inner plating, when processing and forming draw-in groove hole, makes former draw-in groove hole extend to form arc groove to its two side direction through the milling cutter processing directly of 2.0mm cutter.
Beneficial effect of the present invention: utilize cutter footpath 2.0mm milling cutter that existing processing and forming draw-in groove hole is increased compensation 0.1mm, promptly be convenient to USP slot, the quality of production that improves printed circuit board (PCB) and the printed circuit board forming machining hole of operations for forming efficient (can promote 17.3%) through the processing of 2.0mm milling cutter.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Wherein, 1 draw-in groove hole, 2 circuit boards.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with embodiment, further set forth the present invention.
Referring to figure 1 ﹕ printed circuit board forming machining hole; Comprise that circuit board 2 and this circuit board 2 of processing and forming Kong ﹕ that is arranged on the circuit board 2 are formed by stacking four layers of inner plating; Milling cutter at circuit board 2 edges through 2.0mm cutter footpath processes the processing and forming hole, and wherein the edge of circuit board 2 is meant the superficies of circuit board 2; This processing and forming hole is Baltimore groove, and the processing and forming hole is that draw-in groove hole 1 ﹐ extends to form arc groove in two jiaos of positions, bottom, processing and forming hole to both sides, makes draw-in groove of the present invention hole 1 on basis, existing draw-in groove hole, increase compensation 0.1mm.
The detail operations step of making the printed circuit board forming machining hole is following:
(1) transfers pin program (being used for fixing printed circuit board (PCB)) and the moulding program of establishing at the computer that is used for controlling make-up machine;
(2) the pin program is established in execution, plants pin (beat pin and go into pulpboard and circuit board);
(3) upper plate: staff's mounting circuit boards when upper plate, notes viscose glue, confirms identification moulding machining hole position to make-up machine;
(4) CNC moulding: the staff carries out circuit board is milled operation through carrying out the CNC program;
(5) lower plate: pcb board is taken off, just accomplish the processing in processing and forming hole then.
Be the better technique effect of realizing that technological means of the present invention had; It is following that the present invention uses the milling cutter in 2.0mm cutter footpath to carry out the technological parameter of printed circuit board forming machining hole processing: milling cutter specification 2.0mm; Rotating speed S is 29 ± 1 krpm; Following cutter speed F is 0.6 m/min, and withdrawing speed R is 4 m/min, and the moving speed F of X ﹑ y-axis shift is 13 ~ 18 mm/s.
The present invention is by the processing of milling that cutter , carries out the moulding machining hole then of milling in make-up machine chuck gripping 2.0mm cutter footpath, and through 2.0mm milling cutter retapering dihedral camber groove.Utilize the milling cutter processing circuit board 2 of cutter footpath 2.0mm; Existing processing and forming draw-in groove hole 1 is increased compensation 0.1mm, promptly be convenient to USP slot, the quality of production that improves printed circuit board (PCB) and the printed circuit board forming machining hole of operations for forming efficient (can promote 17.3%) through the processing of 2.0mm milling cutter.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from know-why of the present invention; Can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
