Abstract
A kind of printed circuit board (PCB) perforation tool, including perforation printing stencil and perforation printing table, described perforation printing stencil is fixed on perforation printing table upper surface, described perforation printing table inside is the shape chamber of hollow, the inlet scoop inhaling vacuum it is provided with bottom described perforation printing table, the dovetail groove of indent it is provided with in the middle of described perforation printing table upper surface, described perforation printing stencil and dovetail groove form airtight negative pressure shape chamber, the through hole in shape chamber it is communicated with bottom described dovetail groove, described perforation printing stencil is provided with die hole, described die hole is positioned at dovetail groove upper surface scope.Beneficial effect: by the present invention in that and manufacture perforation tool with lucite, existing perforation equipment is improved, with low cost, make simple, convenient and practical, significantly improve the quality of printed circuit board (PCB) perforation product.
Description
Technical field
This invention relates to a kind of printed circuit board (PCB) perforation tool, particularly to a kind of starching perforation for carbon, silver paste hole filled time solve the perforation tool that perforation plug-hole is bad.
Background technology
Traditional carbon slurry perforation, silver paste hole filled silk-screen, relies on the vacuum pump evacuation that screen printing device is self-contained, is sucked by the ink on screen cloth in the hole needing perforation, form via.Starch not every hole in perforation product or silver paste hole filled product to be required for carrying out perforation operation due to a carbon, but this some holes also necessary molding before perforation, this has just disperseed the suction of vacuum pump, it is easily caused ink and is blocked in hole, cause hole obstructed or poor flow, thus causing scrapping of substrate.And reforming equipment increases a vacuum pump costly, and on different product, the quantity in hole is inconsistent, it is necessary to the quantity of perforation is also inconsistent, result in the increase of vacuum pump and might not play expected effect.
Summary of the invention
Goal of the invention: it is an object of the invention to provide and a kind of can improve silk-screen perforation quality, printed circuit board (PCB) perforation tool simple to operate.
Technical scheme: a kind of printed circuit board (PCB) perforation tool, including perforation printing stencil and perforation printing table, described perforation printing stencil is fixed on perforation printing table upper surface, described perforation printing table inside is the shape chamber of hollow, the inlet scoop inhaling vacuum it is provided with bottom described perforation printing table, the dovetail groove of indent it is provided with in the middle of described perforation printing table upper surface, described perforation printing stencil and dovetail groove form airtight negative pressure shape chamber, the through hole in shape chamber it is communicated with bottom described dovetail groove, described perforation printing stencil is provided with die hole, described die hole is positioned at dovetail groove upper surface scope.Owing to the equal corresponding circuits base board of the die hole on perforation printing stencil needing the hole of perforation, perforation printing table and the hole on perforation printing stencil form funnel type, add suction, hole without perforation not do not hole on perforation printing stencil, it is to avoid the dispersion of suction, improves the suction of perforation, the ink using perforation can run through substrate easily, and it being uniformly adhered on hole wall, aperture opening ratio is higher, and hole wall is more smooth.While saving production cost, improve product quality.
In order to improve the efficiency of perforation operation, described perforation printing stencil is additionally provided with hole, location.It is accurately positioned needing realize overlapping with the hole, location on perforation printing stencil of hole, location carrying out on the circuit board substrate of perforation.
In order to reduce cost further, the material of described perforation printing stencil is lucite.
Beneficial effect: by the present invention in that and manufacture perforation tool with lucite, existing perforation equipment is improved, with low cost, make simple, convenient and practical, significantly improve the quality of printed circuit board (PCB) perforation product.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the front view of perforation printing stencil of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, a kind of printed circuit board (PCB) perforation tool, including perforation printing stencil 1 and perforation printing table 2, described perforation printing stencil 1 is fixed on perforation printing table 2 upper surface, described perforation printing table 2 inside is the shape chamber 3 of hollow, the inlet scoop 4 inhaling vacuum it is provided with bottom described perforation printing table 2, the dovetail groove 5 of indent it is provided with in the middle of described perforation printing table 2 upper surface, described perforation printing stencil 1 forms airtight negative pressure shape chamber with dovetail groove 5, the through hole 6 in shape chamber 3 it is communicated with bottom described dovetail groove 5, described perforation printing stencil 1 is provided with die hole 7, described die hole 7 is positioned at dovetail groove 5 upper surface scope.Owing to the equal corresponding circuits base board of die hole 7 on perforation printing stencil 1 needing the hole of perforation, perforation printing table 2 and the hole on perforation printing stencil 1 form funnel type, add suction, hole without perforation not do not hole on perforation printing stencil 1, it is to avoid the dispersion of suction, improves the suction of perforation, the ink using perforation can run through substrate easily, and it being uniformly adhered on hole wall, aperture opening ratio is higher, and hole wall is more smooth.While saving production cost, improve product quality.
As in figure 2 it is shown, the material of described perforation printing stencil 1 is lucite, it is possible to process special perforation printing stencil 1 for every money circuit board.In order to improve the efficiency of perforation operation further, described perforation printing stencil 1 is additionally provided with hole 8, location.
