Abstract
Disclosed in the utility model is an air conduction backing plate. A hollow latticed structure is arranged on the backing plate. When a hole plugging process of a printed circuit board (PCB) process is carried out, the latticed structure on the air conduction backing plate enables air inside holes on the PCB board to be circulated, so that the air conduction role played by the air conduction backing plate in the prior art can also be played by the provided air conduction backing plate. Therefore, the provided air conduction backing plate can be applied to hole plugging plates with different sizes and apertures and can be utilized circularly; and there is no need to prepare lots of air conduction backing plates during the production process, thereby realizing production cost controlling beneficially.
Description
Technical field
The utility model relates to printed circuit board (PCB) (PCB:Printed circuit board) technical field, refers to especially a kind of air guide backing plate.
Background technology
At present consent printed board manufacturing technology is widely used in IC(IC semiconductor manufacture craft) the PCB hard-core technology field such as encapsulating carrier plate, and mobile phone ECM(electromagnetic compatibility is arranged in the consumer electronic product), the also extensive uses such as computer main board, digital product.Owing to electronic product and further miniaturization, cause the density growth of integrated circuit, require high density of integration to solve by adopting the consent structure.Adopt the consent technology can reduce the size of pad, the width of wire, spacing, can also increase the number of plies of printed board, abandon the area of the shared substrate of the unnecessary via of unnecessary articulamentum and use, adopting the purpose of jack process is to make the effect of playing between layers reliable conducting, so the jack process technology has become one of technique important in the printed board manufacturing process technology now.
Wire mark is the consent operating type that present industry is generally used with the aluminium flake consent, mainly be divided into machine printing and hand-printing, its work flow is to adopt printing machine platform to be printed on the web plate that conforms to ectonexine consent aperture location with the scraper of single stroke, by printing scraper pressure printing ink is filled in the aperture, simultaneously for making printing ink fill in smoothly in the hole, needing to prepare can be for the ventilative air guide backing plate in consent aperture, air can be discharged in the consent process smoothly, thereby reach 100% effect that fills up.Because the size of different plates and consent aperture need need to prepare a large amount of air guide backing plates in manufacture process with the air guide backing plate in different consents aperture, are unfavorable for the control of production cost and manufacturing schedule.
The utility model content
Because above-mentioned problems of the prior art, the purpose of this utility model is to propose a kind of air guide backing plate, is applicable to the jack panel in different size thickness and aperture.
Based on a kind of air guide backing plate that above-mentioned purpose the utility model provides, be provided with the fenestral fabric of gong sky on it.
Wherein, the mesh shape of the fenestral fabric of described gong sky is equal-sized rectangle.
Better, the size of described rectangle is: 20 * 40mm.
Optionally, connect by the rib that is of a size of 2-4mm between the fenestral fabric of described gong sky.
Better, connect by the rib that is of a size of 2mm between the fenestral fabric of described gong sky.
Better, the air guide backing plate be shaped as rectangle, and respectively be provided with datum hole at four jiaos of places, be used for fixing with table positions.
Optionally, the shape of described air guide backing plate can also be elected other shapes commonly used such as square, circle as.
Better, the printed circuit board (PCB) of the material selection surface etching off copper of air guide backing plate.
Optionally, the thickness of described air guide backing plate is 0.8-2.5mm.
Can find out from above, a kind of air guide backing plate that the utility model provides, mesh shape structure on the air guide backing plate can play the air guide effect as air guide backing plate in the prior art, simultaneously, it can be applicable to the jack panel in different size thickness and aperture, can be recycling, no longer need in process of production to prepare a large amount of air guide backing plates, be conducive to production cost control.
Description of drawings
Fig. 1 is a kind of air guide backing plate of the utility model embodiment schematic diagram.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with specific embodiment, and with reference to accompanying drawing, the utility model is further described.
A kind of air guide backing plate that the utility model provides is provided with the fenestral fabric 1 of gong sky on it.
With reference to figure 1, it is a kind of air guide backing plate embodiment schematic diagram of the utility model embodiment.
Wherein, the mesh shape of the fenestral fabric 1 of described gong sky is equal-sized rectangle.
Better, the size of described rectangle is: 20 * 40mm.
Optionally, 1 rib 2 connection by being of a size of 2-4mm of fenestral fabric of described gong sky.
Better, 1 rib 2 connection by being of a size of 2mm of the fenestral fabric of described gong sky.
Better, the air guide backing plate be shaped as rectangle, and respectively be provided with datum hole 3 at four jiaos of places, be used for fixing with table positions.
Optionally, the shape of described air guide backing plate can also be elected other shapes commonly used such as square, circle as.
Better, the printed circuit board (PCB) of the material selection surface etching off copper of air guide backing plate.
Optionally, the thickness of described air guide backing plate is 0.8-2.5mm.
A kind of air guide backing plate that the utility model provides is fixed on the workbench by datum hole, then by placing nail bed pin jack panel is fixed on the air guide backing plate.When pcb board consent process was carried out, the mesh shape structure on the air guide backing plate prevented that simultaneously printing ink pollutes the deck plate face in the via so that the hole inner air flow on the printed circuit board (PCB) enters in the hole printing ink smoothly, guarantees that the amount of filling in of printing ink or resin is full.
The mesh shape of the fenestral fabric of described gong sky is rectangle in the present embodiment; it may occur to persons skilled in the art that; its set-up mode is not unique; every can playing similarly so that other mesh shapes of the hole inner air flow effect on the printed circuit board (PCB) such as square, circular or other irregular figures, all belong to the present invention and protect category.
Can find out from above, a kind of air guide backing plate that the utility model provides, mesh shape structure on the air guide backing plate can play the air guide effect as air guide backing plate in the prior art, simultaneously, it can be applicable to the jack panel in different size thickness and aperture, can be recycling, no longer need in process of production to prepare a large amount of air guide backing plates, be conducive to production cost control.
Those of ordinary skill in the field are to be understood that: the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle; any modification of making, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
