Abstract
The utility model discloses a double-sided filled aluminium base PCB board, comprising two line layers and a carrier plate between the two line layers, the carrier plate is an aluminium base metal carrier plate, a mechanical hole is arranged in the aluminium base metal carrier plate, and the mechanical hole is filled with insulating resin, a conducting hole is arranged on the insulating resin in the mechanical hole. The double-sided filled aluminium base PCB board can satisfy the effects of insulation and conduction at the same time via the aluminium base metal carrier plate.
Description
Technical field
The utility model relates to a kind of pcb board, and the support plate in the middle of particularly a kind of two line layers is the pcb board of aluminium based metal support plate.
Background technology
On the insulation board of certain size, be processed into the figure of some conductions, and cloth porose (as element jointing holes, fastener hole, plated-through hole etc.), be the chassis with it, can realize interconnecting between the components and parts, this wiring plate claims printed circuit board (PCB) (pcb board).
The pcb board that the etching method of at present extensive use is made, on copper coated foil plate, carry out etching exactly selectively, obtain the figure of required circuit, basic manufacturing process flow is: metal-clad plate--＞cut out plate--＞boring--＞press dry film (or roller coating wet film)--＞exposure imaging--＞etching--＞striping--＞solder-mask printing printing ink--＞moulding--＞surface treatment--＞finished product.
Print the sandwich support plate of internal layer of pcb board conventional design double sided board, during assembling to satisfy the heat sinking function of special electronic devices and components.But designing normally and all adopt the insulation glass when core material is selected for use is core material, influences heat sinking function and shorten useful life of electrical equipment in electric use.
The utility model content
Technical problem to be solved in the utility model provides a kind of while and can finish the pcb board of the aluminium based metal support plate of insulation, two functions of conducting.
In order to solve above-mentioned technical problem, the technical solution of the utility model is: a kind of two-sided sandwich aluminum base PCB plate, comprise the support plate between two line layers and two line layers, described support plate is the aluminium based metal support plate, the aluminium based metal support plate is provided with mechanical hole, machinery is filled with insulating resin in the hole, and insulating resin is provided with via in the described mechanical hole.
By the sandwich glass support plate in the middle of the two-layer circuit is changed to the aluminium based metal support plate with high heat sinking function, have high heat dispersion thereby play, and, satisfy the synchronous effect of insulating simultaneously with conducting by the boring in the insulating resin.The utility model has the advantages that:
1, promotes the high heat dispersion of pcb board self;
2, can prolong electric useful life;
3, save electric manufacturing cost, can fully phase out the heat-dissipating aluminium plate of the load in the electric assembling, reduce because of scrapping that burr in the hole causes.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is an aluminium based metal support plate machine drilling structural representation.
Fig. 2 is the structural representation in insulating resin filling machine hole.
Fig. 3 makes structural representation for the outer-layer circuit etching.
Embodiment
Two-sided sandwich aluminum base PCB plate, comprise the support plate between two line layers and two line layers, described support plate is the aluminium based metal support plate, and the aluminium based metal support plate is provided with mechanical hole, machinery is filled with insulating resin in the hole, and insulating resin is provided with via in the described mechanical hole.Its production technology is as follows:
It is carrier that the connection carrier of the via of two line layers adopts the aluminium based metal conductor, and by forming mechanical hole after the machine drilling, as shown in Figure 1.
To realize the metallic carrier insulation behind the insulating resin filling machine hole, as shown in Figure 2, the purpose of this step is to make it to possess insulation function.After carrying out outer copper sheet pressing again.
Carry out 2 machine drilling in insulating resin filling position again after the copper sheet pressing, form mechanical hole.Boring just can realize insulation with the aluminium based metal support plate like this.
The last metallization of heavy copper hole wall and electroplating surface, outer-layer circuit etching and the surface insulation welding resistance ink printing that carries out again as shown in Figure 3, thus realize that metallic carrier possesses insulation and high heat sinking function is the two-sided sandwich aluminum base PCB plate of one.
The foregoing description limits the utility model never in any form, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in the protection range of the present utility model.
