Abstract
The utility model relates to a PCB board via-hole oil plugging device, in particular to a PCB board via-hole plugging device which facilitates the full plugging of the ink of the via hole and is free from adhering the ink on a silk-screening machine table-board. A porous cushion plate is arranged between a PCB board and a silk screening machine; a mesh plate, the PCB board and the cushion plate are overlapped with each other and are superposed onto the silk screening machine table-board. With the porous cushion plate, the ink has higher falling space, and the ink is easier to enter into the via hole which is plugged with oil and the plugged oil can be full; moreover, the ink is free from adhering to the silk screening machine table-board to cause the cross pollution, so that the product quality can be ensured, and the quality hidden problem of the prior art can be eliminated.
Description
Technical field:
The utility model relates to a kind of pcb board and crosses stopple oil device, particularly a kind ofly can make printing ink fully fill up the pcb board that via hole and printing ink can not be bonded on the screen printer table top to cross stopple oil device.
Background technology:
Pcb board needs the Via via hole is blocked with printing ink before doing welding resistance, prevent that pcb board is when the packaging process of downstream, in via hole, there is tin sweat(ing) and causes short circuit, this will fill up in the time of just need filling in oil in the pcb board via hole, and promptly quantity of ink is enough, the plug oil level is put (position of the half tone leakage of oil China ink of biting and the position that pcb board need be filled in printing ink) will be precisely.Existing P CB plate is crossed stopple oil way, is to cross the half tone hollow out of biting of hole site corresponding to pcb board, need not fill in other oily positions and shut with the sensitization slurry, is filled in the corresponding oil of filling in the hollow out position on the half tone of biting of pcb board via hole of oil and operates.This way is printed when oil plug on the one hand and easily printing ink was penetrated another side from the one side of via hole and enter on the screen printer table top, on the other hand because the screen printer table top is smooth, form sealing between the pcb board of table top and quilt plug oil, via hole is just as blind hole, printing ink is difficult to fill up via hole, the poor reliability of plug oil operation, the pcb board quality is difficult to ensure.
Summary of the invention:
The purpose of this utility model is to overcome the deficiencies in the prior art, eliminates the hidden danger of quality that prior art exists, and can make printing ink can fully fill up via hole, and printing ink can not be bonded at again on the screen printer table top and influences the plate face quality of next piece pcb board.
The purpose of this utility model can realize by following measure:
To cross stopple oil device by what the half tone of biting, pcb board were formed, on the half tone of biting with pcb board via hole relevant position by hollow out, need not fill in and then shut on the half tone of biting of position of oil with the sensitization slurry.The half tone of biting directly places by on the pcb board of plug oil, unlike the prior art be, a backing plate with holes is set between pcb board and screen printer table top in addition, half tone, pcb board, backing plate three face overlap with face is vertical, overlay on the screen printer table top.Backing plate wherein with holes generally adopts the FR4 material, and plate thickness is about 0.8-1.2mm, and the Kong Yuxu of backing plate with holes fills in the hollow out position axial symmetry correspondence one by one on the via hole of oily pcb board, the half tone, and the aperture is about 0.9-1.1mm.
The utility model has used backing plate with holes to make printing ink that higher drop space arranged, make the easier via hole and the plug oil ratio of being filled in oil of entering of printing ink fuller, and printing ink can not stick on the screen printer table top, form cross pollution, make product that the quality guarantee arranged, eliminated the hidden danger of quality that prior art exists.
Description of drawings:
The pcb board of Fig. 1 prior art is crossed stopple oil device sectional view.
Fig. 2 pcb board of the present utility model is crossed stopple oil device sectional view.
Identifier declaration among the figure: pcb board 1, screen printer 2, backing plate with holes 3.
Specific embodiments:
Below by further the utility model being described in conjunction with the accompanying drawings:
Fig. 1 is that the pcb board 1 of prior art is crossed stopple oil device.Pcb board 1 by plug oil is placed directly on screen printer 2 table tops, clamp-on pcb board 1 via hole by the printing ink that the ready-made half tone of biting will penetrate, because its poor operability and the pore volume filled in of institute easily plug are discontented with, or the printing ink of clamp-oning passes via hole and drops on the screen printer table top.
Fig. 2 is that pcb board 1 of the present utility model is crossed stopple oil device.Adopting thickness is the backing plate with holes 3 of 0.8-1.2mm FR4 material, backing plate with holes 3 apertures are about 0.9-1.1mm, Kong Yuxu on the backing plate 3 with holes fills in the via hole of oily pcb board 1, the hollow out position on half tone axial symmetry correspondence one by one, be followed successively by the half tone of biting, pcb board 1, backing plate with holes 3 from top to bottom, three's face overlaps with face is vertical, overlays on screen printer 2 table tops.Although via hole still is a blind hole, pcb board 1 and screen printer 2 table tops have had the gap of 0.8-1.2mm, and the printing ink entry pressure greatly reduces, just be easy to be full of via hole, and contract under the effect of ink surface tension, be adsorbed in the via hole, both filled via hole, unlikely again contamination screen printer 2 table tops.
More than be a kind of PCB provided by the utility model to be crossed stopple oil device be described in detail, described the manufacturing process and the application specific data of product that the utility model is described herein the performance of product that the utility model is described is set forth, above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
