Background technology
In art of printed circuit boards, the printed circuit central layer can supply printed circuit central layer factory to be processed into multilayer printed circuit central layer (PCB), is widely used in fields such as electronics, computer, communication, Aero-Space, military affairs.
In the prior art, traditional multilayer printed circuit central layer is as shown in Figure 2 in the pressing process, and the multilayer printed circuit central layer is in the pressing process; Need core material directly be positioned on the rivet driver table top; Because existing rivet mesa designs is unreasonable, therefore cause the scratch of central layer brown, P.P film to be subject to the anti-glutinous internal short-circuit that causes of metallic foreign body easily; Pressing foreign matter and layer situation such as inclined to one side perhaps occur, cause the printed circuit panel products defective.
The utility model content
The purpose of the utility model; Be that above-mentioned existing rivet driver mesa structure is unreasonable in order to solve, the scratch of one-tenth central layer brown; The P.P film is subject to the anti-glutinous problem that causes internal short-circuit of metallic foreign body; A kind of activity separate type rivet table top that is used for multilayer board is provided, has the advantage that makes the core material accurate positioning, reduces the inclined to one side scrappage of layer.
The purpose of the utility model can reach through following technical scheme:
Be used for the activity separate type rivet table top of multilayer board, its design feature is: comprise the rivet table top and with the spongy layer of rivet table top articulated, be provided with the riveted groove of plurality of outward socket rivet board in the edge of rivet table top; Said spongy layer is through the screw activity or be fixedly connected on the rivet table top, the fluting that the edge of spongy layer is provided with the riveted groove is big or small, shape is identical with the position; Be formed for the activity separate type rivet table top of multilayer board through the pivot bush unit of riveted groove and rivet board.
The purpose of the utility model can also reach through following technical scheme:
Further Technological improvement plan is: the thickness of said rivet table top can be between 40mil～65mil.
Further Technological improvement plan is: said riveted groove can be rounded with fluting, and its diameter can be 40～60mm.
Further Technological improvement plan is: said screw can have three, wherein two sides that are arranged on the rivet table top, another is arranged on relative opposite side.
Further Technological improvement plan is: the size of said screw can be between 2mm～4mm.
The utlity model has following outstanding beneficial effect:
1, the utility model is owing to be provided with the spongy layer of movable joint at the rivet table top, therefore can avoid directly being positioned over brown face scratch when causing foreign matter anti-glutinous or lavatory material or operation on the rivet driver table top to wiring board, has the beneficial effect that the protection workpiece is not damaged.
2, the utility model forms movable syndeton through the pivot bush unit of riveted groove and rivet board; And then can under the restriction of riveted groove, carry out the rivet hole riveting job; Make that the core material and the P.P film storing location of wiring board are more accurate, to reduce a layer scrappage partially.
Description of drawings
Fig. 1 is the location sketch map of the utility model to wiring board;
Fig. 2 is the schematic flow sheet of traditional rivet operation;
Fig. 3 is used for the schematic flow sheet of rivet operation for the utility model.
Wherein, 1-rivet table top, 2-spongy layer, 3-riveted groove, 4-Pin nail, 5-fluting, 6-internal layer chip, 7-P.P film.
Embodiment
Specific embodiment 1:
Fig. 1 and Fig. 3 constitute the specific embodiment 1 of the utility model.
With reference to Fig. 1, present embodiment comprise rivet table top 1 and with the spongy layer 2 of rivet table top 1 articulated, be provided with the riveted groove 3 of plurality of outward socket rivet board in the edge of rivet table top 1; Said spongy layer 2 is movable or be fixedly connected on rivet table top 1 through screw 4, and the edge of spongy layer 2 is provided with and riveted groove 3 sizes, fluting 5 that shape is identical with the position; Be formed for the activity separate type rivet table top of multilayer board through the riveted groove 3 and the pivot bush unit of rivet board.
In the present embodiment, the thickness of said rivet table top 1 is between 40mil～65mil.The diameter of said riveted groove 3 and fluting 5 is 50mm.Said screw 4 has three, two sides that are arranged on rivet table top 1 wherein, and one is arranged on relative opposite side.Said screw 4 is of a size of 3.175mm.Said internal layer chip 6 is not gone up with P.P film 7 can be placed on certain one deck frame before being placed in screw 4 different layers.
The application process of the utility model is following:
With reference to Fig. 3, make earlier the tool that is used to locate with the rivet operation, choose sheet material; Pressing X-RAY holes on sheet material, holds the riveted groove after the moulding successfully, spreads a spongy layer; Cartridge screw fixes spongy layer, and the core material of placing on the removing layer frame then is placed on the screw of tool and positions, and gets then that the P.P film is placed in core material in advance on layer frame; Get that the respective layer central layer is placed on the P.P film in advance on layer frame, after cover was accomplished in advance, tool was gone up operation according to the mould pin that riveted groove position is placed in the rivet table top.Avoided the anti-sticking and lavatory material of metallic foreign body like this; Core material is placed in the tool plate; Become the friction of tool and operation table top, can not cause the brown scratch, thereby carry out riveted again to promote the riveted operating efficiency at the preparatory cover of tool plate in advance; Before riveted, overlap in advance and the location in advance, reduce the inclined to one side scrappage of pressing layer greatly.
