Description
Technical field
The utility model relates to IC manufacturing fields, and in particular to a kind of pcb board gasket.
Background technique
As modern electronic product is increasingly to portable, miniaturization, highly integrated, high performance trend development, electronics industry
Higher and higher demand is proposed to circuit board miniaturization.In recent years, high density interconnecting board (HDI plate, High Density
Interconnector) it can reduce PCB cost because having, increase line density, more preferably electrical property and signal correctness, reliable
It spends good, many excellent properties such as can improve radio frequency interference/Electromagnetic Interference/Electro-static Driven Comb and is rapidly developed.
In HDI plate preparation process, the mode for generalling use plank stacking carries out turnover between each process, and two adjacent
Plank between separated using gasket, avoid two planks from directly contacting.Since route is highly integrated on HDI plate, each route
The distance between it is comparatively very small, and there are many Blind holes, to ensure that HDI plate can have above-mentioned excellent properties,
HDI plate requires the clean-up performance of gasket very high.In processing procedure circular flow, if the foreign matters such as dust on gasket, dirty are to HDI
Plate pollutes or blocks blind hole, be easy to cause HDI plate poor plating, and HDI plate is directly scrapped when serious, causes largely to waste.
Therefore how to reduce, even avoid pollution of the HDI plate by the foreign matters such as dust, dirty in processing procedure circular flow, being this field skill
Art personnel technical problem urgently to be resolved.
Utility model content
The utility model provides a kind of pcb board gasket, to reduce HDI plate in processing procedure circular flow by ash
The foreign substance pollutions such as dirt, dirty cause the risk of HDI blind hole plug-hole, poor plating.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is: a kind of pcb board gasket, including a side
The main body of shape, the main body are equipped with several equally distributed hollow holes, and four sides of the main body retain and four equal roundings in angle
The distance between edge of angle, the edge of the hollow hole and the main body is 40~45mm, the hole edge of two neighboring hollow hole
Away from for 24~26mm, the main body with a thickness of 0.8~1mm, the main body uses PP material.
Further, the hollow hole is circular hole.
Further, the diameter of the circular hole is 40~45mm.
Further, the hollow hole is rectangular opening.
Further, four equal rounded corners in angle of the rectangular opening.
Pcb board gasket described in the utility model, including a rectangular main body, the main body is equipped with several be uniformly distributed
Hollow hole, four sides of the main body retain and four equal rounded corners in angle, the edge at the edge of the hollow hole and the main body
The distance between be 40~45mm, the hole back gauge of two neighboring hollow hole is 24~26mm, the main body with a thickness of 0.8~
1mm, the main body use PP material.It has the advantages that
1. gasket is equipped with hollow hole, gasket is made to meet saving while pad plays buffer action between two pcb boards
Material reduces pcb board by gasket pollution, the risk of plug-hole in addition, decreasing the contact area between gasket and pcb board；
2. gasket uses the design method of main body quadrangle rounded corner and rectangular opening rounded corner or circular hole, avoids the occurrence of wedge angle and draw
Hurt pcb board, causes poor plating.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the first specific embodiment of pcb board gasket described in the utility model；
Fig. 2 is the structural schematic diagram of the second specific embodiment of pcb board gasket described in the utility model.
It is as shown in the figure: 100- main body, 210- circular hole, 220- rectangular opening.
Specific embodiment
In order to make it easy to understand, illustrating the technical characteristics of the utility model below with reference to embodiment.It should be understood that these embodiments
It is merely to illustrate the utility model rather than limitation the scope of the utility model.
Embodiment 1
As shown in Figure 1, pcb board gasket described in the utility model, the rectangular main body 100 including a PP material, the master
Body 100 is equipped with several equally distributed hollow holes.Four sides of the main body 100 retain, and conveniently take when to use described
Pcb board gasket, and the integrality on 100 4 side of main body also can reduce the risk that the pcb board gasket scratches pcb board.Institute
Four equal rounded corners in angle for stating main body 100, by avoiding horn structure design from further decreasing the risk that pcb board is scratched.Institute
State main body 100 with a thickness of 0.8~1mm, satisfaction does not also waste while being effectively isolated two pcb board functions because gasket is blocked up
Material.
Further, reasonable distance is set between two neighboring hollow hole, between hollow hole and the edge of main body 100,
Guarantee that the pcb board gasket has enough intensity, convenient for taking and operation；There is sufficient intensity in pcb board gasket
Under the premise of, hollow hole is answered as big as possible, to reduce the number of openings, is reduced the contact area of gasket and pcb board, is reduced gasket pair
Pcb board pollutes, blocks the risks such as blind hole.Specifically, with continued reference to shown in Fig. 1, in the present embodiment, the hollow hole is
Circular hole 210 will not scratch pcb board, and the diameter of the circular hole 210 is 40~45mm, and the hole back gauge of two neighboring circular hole 210 is 24
