Abstract
A lubrication base board for circuit board drilling comprises base material and an aquosity lubrication layer, wherein the base material is used for boards for rebasing of printed circuit board drilling, the aquosity lubrication layer is tightly combined on the surface of the base material to enhance lubrication and heat dissipation performance of the surface of the base material, a lubrication base board structure is formed, and the upper surface and the lower surface of the lubrication base board structure both comprise lubrication layers. The base material is density boards or fiber boards, the aquosity lubrication layer is a coating composed of aquosity white glues and vinyl acetate, and the coating is coated on the surface of the base material through a roller wheel. A layer of protection paper arranged on the surface of the lubrication base board is processed by hardening agents. According to the lubrication base board, as the aquosite lubrication layer has the heat dissipation effect, a drill point is not deformed, and drilling accuracy is enhanced. By means of the lubrication effect of the aquosity lubrication layer, abrasion of the drilling point is reduced, long service life of the drilling point is prolonged, and by means of the hardened protection paper, production of burrs is reduced.
Description
Technical field
The utility model is that relevant a kind of circuit boring is with lubricating backing plate, espespecially utilize a kind of lubricating pad plate structure of aqueous lubricating layer, it is had reduce the drill point wear rate, promote service life and get rid of rapidly heat energy, drill point can not be out of shape and strengthen the multi-efficiency such as boring precision.
Background technology
At present in the processing procedure of printed circuit board (PCB) (PCB); it must coordinate the design of predetermining circuit plate and be drilled with several through holes on substrate; and in the operation of boring, in order to prevent from processing the damage of table top and the wearing and tearing of drill bit, therefore can place a bottom pad plate as protection at base plate bottom.
On the other hand, because the boring edge that easily causes in when boring produces burr and cutting, so the material of this bottom pad plate must have burr, the cutting that produces when reducing this boring, and reaches the convenience of its quality and follow-up handling process.Therefore; the bottom pad plate that present known circuit boring is used is to adopt fiberboard to make; the surface of its this fiberboard or bottom surface are coated with respectively the formation that ceramic medicine raw material or UV pottery paint etc. increase its hardness strengthening layer; another kind is to adopt bakelite plate; even with the upper and lower surface of aluminium foil laminate synthesis type at bottom pad plate; forming according to this aluminium plywood, although above three's bottom pad plate all can reach substrate or the even protection of board of drill bit, but still is that some disappearance is what need to improve to strengthen.
As fiberboard, its density has basic, normal, high sheet material respectively, its advantage is that it there is no the generation of pollution problem, but still have the disappearance be because of the hardness on top layer limited, so when boring, produce burr and cutting for substrate than being easier to after boring, also cause decline for the quality of circuit board, and also can add a little inconvenience in follow-up operation; Moreover if this fiberboard adopts the higher board making of density, its processing procedure is aobvious loaded down with trivial details, and production efficiency reduces, and therefore easily causes the situation of high cost to occur.
moreover, as bakelite plate, its affiliated one more expensive sheet material, its advantage is because the hardness of this bakelite plate is higher, therefore when location drilling, can bear higher boring pressure to reach the effect that easily is drilled with, but its disappearance is, because this bakelite plate belongs to the higher sheet material of hardness, be easier to injury for the drill bit ratio, and the cost of this bakelite plate is higher, belong to construction store for this bottom pad plate, such cost can be a considerable expense really, in addition, add that bakelite plate uses later must be with waste disposal the time, the use method of burying is processed and can't be caused decomposition, and use firing method can produce the situation of toxic gas, and therefore use in the situation of bakelite plate, easily there is the problem of environmental protection waste disposal to produce.
In addition, though this aluminium plywood has heat radiation effectiveness, its radiating mode belongs to the heat conduction, in other words, heat distribution is in the aluminium plywood, more in addition cooling by air, in real time not lubricated drill bit drill point, contact the moment of this aluminium plywood when this drill bit drill point, will produce the destructive power of hot source point, the function that causes this drill bit drill point gradually to degenerate and cut.
Edge this, the inventor is because the disappearance of above-mentioned prior art, if can come cooling this drill bit drill point with lubricating system in conception, eliminate the destructive power of hot source point, reduce simultaneously the burr that produce of holing and cut to improve quality, hope can be whereby to reach the characteristic that reduces the drill point wearing and tearing and meet again economic benefit.
The utility model content

The technical scheme that its technical problem that solves the utility model adopts is:
A kind of circuit boring is characterized in that with lubricated backing plate, comprising:
One base material is for being used for the sheet material of the rebasing use of printed circuit board drilling;
One aqueous lubricating layer, it is combined closely at this substrate surface, so as to strengthening the lubricated and thermal diffusivity of substrate surface, consists of according to this lubricating pad plate structure that a upper and lower surface all has lubricating layer.
According to before taking off feature, this base material is intensive plate or fiberboard.
Again, this aqueous lubricating layer material is consisted of coating by water-based white glues and vinyl acetate.
Again one, this coating is coated on this substrate surface with running roller.
Separately, be provided with one deck protection sheet in described lubricated backing plate surface.
Another, this protection sheet is the structure of processing through curing agent.
Whereby, the utility model use have the splendid aqueous lubricating layer of radiating effect with this base material as combination, therefore can reach the multinomial effect such as reduction drill point wearing and tearing, to guarantee the economic benefit of production capacity steady decrease fraction defective.
The beneficial effects of the utility model are, due to aqueous lubricating layer tool heat radiation effectiveness, drill point can not be out of shape and strengthen the effect of boring precision; Due to the lubricated effectiveness of aqueous lubricating layer tool, can reduce the drill point wearing and tearing and the effect in increase drill point life-span; Due to the protection sheet after sclerosis, can reduce the effect that burr produces.
