Size be more than aluminium flake net size；And uniformly offer on opening area multiple when ink or resin carry out consent by the hole
The boring that discharged of air.
Wherein, the pore size of each boring is 1.6mm, and the pore size of aluminium flake each consent online is 0.2mm.
Wherein, each positioning thimble all includes locating rod, the positioning convex extending from locating rod one end side and from fixed
The pin that position bar one end upper surface extends, is all caved inward at each knuckle of described printed circuit board to have and is fitted with positioning convex phase
The detent joined, is equipped with, at described each knuckle of aluminium flake net, the set hole being adapted with pin, each pin falls into corresponding
Set in the hole and each positioning convex falls into after in corresponding detent, printed circuit board is fixedly connected with aluminium flake net.
Wherein, the diameter of each pin is between 2.0-3.5mm.
The beneficial effects of the utility model are: compared with prior art, the plug of the printed circuit board that this utility model provides
Pore structure, carries out consent using aluminium flake net, and it is off the net by positioning thimble, the printed circuit board needing consent to be fixed on aluminium flake
Surface, the advantage of this structure is that during consent, aluminium flake deformation is little, and during consent, para-position is accurate；Meanwhile, aluminium flake silk screen is placed on and covers copper
Plate upper surface and both be directed at placement after again copper-clad plate is placed on above silk-screen board, this copper-clad plate is carried out in ink or resin
During consent, play the effect that the air of in the hole is discharged；The improvement of said structure, the quality of effective consent, and can will fill in
The ink plug of in the hole uniformly with full, it is to avoid the phenomenon done over again Yu scrap there is, the quality of effective guarantee consent.

Specific embodiment
In order to more clearly state this utility model, below in conjunction with the accompanying drawings this utility model is further described.
Refer to Fig. 1-2, the consent structure of printed circuit board of the present utility model, including copper-clad plate 10, aluminium flake net 11 and
Silk-screen silk screen (not shown)；Aluminium flake net 11 forms aluminium flake silk screen after being fitted on silk-screen silk screen, needs the printed circuit board of consent
13 by multiple positioning thimbles 12 be fixed on aluminium flake silk screen lower surface after, aluminium flake silk screen be placed on copper-clad plate 10 upper surface and both
After be aligned is placed, printed circuit board 13 is located between aluminium flake silk screen and copper-clad plate 10, and this copper-clad plate 10 is placed on screen printer
Above platform；Multiple consents 111, the aperture of each consent 111 and the printed circuit board needing consent are evenly distributed with aluminium flake net 11
13 pore size is consistent.
The consent structure of the printed circuit board providing compared to the situation of prior art, this utility model, using aluminium flake net
11 carry out consent, and by positioning thimble 12, the printed circuit board 13 needing consent are fixed on aluminium flake surface off the net, this knot
The advantage of structure is that during consent, aluminium flake deformation is little, and during consent, para-position is accurate；Meanwhile, aluminium flake silk screen is placed on copper-clad plate upper surface and two
Copper-clad plate is placed on above silk-screen board after placing again by person's be aligned, and this copper-clad plate, when ink or resin carry out consent, is played
The effect that the air of in the hole is discharged；The improvement of said structure, the quality of effective consent, and can be by the ink plug in consent
Uniformly with full, it is to avoid the phenomenon done over again Yu scrap there is, the quality of effective guarantee consent.
In the present embodiment, the sealing area that copper-clad plate 10 includes opening area 101 and is located at opening area 101 periphery
102, the size of opening area is more than the size of aluminium flake net 11；And uniformly offer on opening area 101 multiple in ink or tree
Fat carries out the boring 103 during consent being discharged the air of in the hole.The pore size of each boring 103 is 1.6mm, aluminium flake net
On 11, the pore size of each consent 111 is 0.2mm.In this structure, using thickness, the aluminium flake for 0.2mm carries out shining net, and holes
Bigger than the aperture of consent more than 3 times of aperture, by the fr4 being drilled copper-clad plate with need printing aluminium flake net be aligned, be placed on
Above silk-screen board, when ink or resin carry out consent, the air of in the hole can be discharged by boring.
In the present embodiment, each positioning thimble 12 all includes locating rod 121, extends from locating rod 121 one end side
Positioning convex 122 and the pin 123 extending from locating rod 121 one end upper surface, equal at each knuckle of printed circuit board 13
Cave inward the detent being adapted with positioning convex 122, is equipped with and is adapted with pin at each knuckle of aluminium flake net
Set hole, each pin falls into corresponding set in the hole and each positioning convex falls into after in corresponding detent, printed circuit board
It is fixedly connected with aluminium flake net.Pass through the positioning of positioning convex and pin in this structure, to ensure the accuracy of para-position, and then ensure
The precision of consent and plumpness.The diameter of each pin is between 2.0-3.5mm.Aluminium flake net, printed circuit board (PCB) and cover in this case
Copper coin is all square, all can be positioned using positioning thimble, and then ensure that the accuracy of positioning at four knuckles.
Traditional handicraft predominantly adopts wire mark consent, and class's yield (8 hour/class) is 500, and consent poor quality,
Partial hole is had to fail the uniformly full of plug；800-1000 can be improved using class's yield after the aluminium flake consent of this case to open, production efficiency
Substantially lifted at double, and the uniform pore diameter filled in is full, effectively ensure the quality of consent.
