Description
Technical field
The utility model relates to PCB manufacture technology field, particularly relates to a kind of PCB jigsaw structure.
Background technology
In PCB manufacture field, cause because each PCB finished product is not of uniform size, usually need to be combined into certain size making during making and could meet machinery equipment requirement, be called PCB jigsaw.Concrete operable PCB jigsaw mode is very many, such as, have cis jigsaw, anglec of rotation jigsaw, male and female face jigsaw and composite type jigsaw etc.
Wherein, the mode of described male and female face jigsaw as shown in Figure 1, to be spliced in the mode of AB (i.e. male and female face) by two pieces of (or polylith) veneers and is produced in one side.The mode of above-mentioned male and female face jigsaw has a lot of advantages, all higher for SMT whole efficiency, cost control.The production of double sided board only needs one-time process to complete, and improves the utilance of chip mounter greatly.Also can not cause too much waste for manufacturing on-the-spot management intensity, being very suitable for production in enormous quantities pattern.
When but above-mentioned male and female face jigsaw pattern has the element that volume is comparatively large or thermal endurance is not good in PCB single board, the problem easily causing the larger element of volume to come off when secondary back welds and cause the not good element of thermal endurance to burn.And for substrate manufacturers, quality control difficulty is comparatively large, and in actual production, veneer scrappage is high compared with other jigsaw modes.
Therefore, prior art need development.
Summary of the invention
In view of above-mentioned the deficiencies in the prior art part, the purpose of this utility model is to provide a kind of PCB jigsaw structure, is intended to solve PCB male and female face jigsaw quality control difficulty in prior art comparatively large, easily causes the problem that the not good element of thermal endurance burns.
In order to achieve the above object, the utility model takes following technical scheme:
A kind of PCB jigsaw structure, comprise the jigsaw that some PCB single board of splicing in male and female face mode are formed, wherein, described PCB jigsaw structure also comprises: the reinforcement being arranged on described jigsaw periphery; Described reinforcement is provided with a heat conduction limit;
Described reinforcement is provided with some wedge shape contiguous blocks; The one side of one end that described contiguous block is narrow and described PCB single board bonds with fixing described PCB single board;
Described reinforcement is also provided with location hole and is used to indicate the indicator hole of jigsaw positive and negative;
The bottom surface of described jigsaw is also provided with the supporting structure of the element for supporting described jigsaw reverse side.
Described PCB jigsaw structure, wherein, described reinforcement is specifically arranged on the both sides up and down of described jigsaw.
Described PCB jigsaw structure, wherein, described supporting structure is fenestral fabric, is fixedly connected with described reinforcement.
Described PCB jigsaw structure, wherein, the width of described reinforcement is 5-8mm.
Described PCB jigsaw structure, wherein, described heat conduction limit is specially the heat-conducting plastic layer be arranged in reinforcement.
Beneficial effect: a kind of PCB jigsaw structure that the utility model provides, by arranging heat conduction limit on reinforcement, effectively raises the heat dispersion of jigsaw, avoids causing burning of element due to overheated.Also be provided with the element that extra supporting construction is jigsaw reverse side and certain support is provided.Above-mentioned jigsaw vibrational power flow, can improve the yields in substrate production process preferably, reduces the difficulty of quality management and control, is conducive to promoting the use of of male and female face jigsaw mode, has a good application prospect.
Accompanying drawing explanation
Fig. 1 is the male and female face jigsaw structural representation of prior art.
Fig. 2 be the PCB jigsaw structure of the utility model specific embodiment face structural representation.
Fig. 3 is the side-looking structural representation of the PCB jigsaw structure of the utility model specific embodiment.
Embodiment
The utility model provides a kind of PCB jigsaw structure.For making the purpose of this utility model, technical scheme and effect clearly, clearly, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
In the utility model, PCB single board is used to represent last each PCB finished product.Each PCB finished product is double-sided printing, that is PCB single board has A face and two sides, B face.
Described jigsaw refers to by above-mentioned even number PCB single board in the manner shown in figure 1, the PCB jigsaw that male and female face is spliced to form.Thus, described jigsaw also has front and reverse side.
As shown in Figure 2, be a kind of PCB jigsaw structure of the utility model specific embodiment, comprise the jigsaw 100 that some PCB single board of splicing in male and female face mode are formed and the reinforcement 200 being arranged on described jigsaw periphery.
Described reinforcement 200 is also provided with location hole 240 and is used to indicate the indicator hole 250 of jigsaw positive and negative, position man-hour for jigsaw and play foolproof function adding.
Described reinforcement 200 is provided with a heat conduction limit 210.Contiguous block or other modes should be passed through in described heat conduction limit 210, contact with each veneer 10 in jigsaw, thus in the fabrication process for PCB single board provides extra heat dissipation channel.Described heat conduction limit can be arranged on the internal layer of reinforcement, also can be arranged on top layer or other suitable positions of reinforcement.
In specific embodiment of the utility model, described heat conduction limit is specially the heat-conducting plastic layer be arranged in reinforcement.Use heat-conducting plastic layer can have good thermal conductivity and insulation property concurrently simultaneously, when avoiding use metal as heat-conducting layer, need the troublesome operation of heat-conducting layer being carried out to insulation processing.
As shown in Figure 3, described reinforcement 200 is provided with some wedge shape contiguous blocks 220.The one side (i.e. A face or B face) of one end that described contiguous block 220 is narrow and described PCB single board bonds with fixing described PCB single board.The PCB single board fixed form of above-mentioned one side support formula, can be convenient to PCB single board one side machine after and reinforcement depart from.
The bottom surface of described jigsaw is also provided with the supporting structure of the element for supporting described jigsaw reverse side.Described supporting structure can be set to adjustable structure thus the convenient processing to jigsaw bottom surface.
Concrete, as shown in Figure 2, described reinforcement 200 is specifically arranged on the both sides up and down of described jigsaw.Preferably, the width of described reinforcement can be set to 5-8mm, and optimum can be set to 7mm.The raising that wide reinforcement is unfavorable for baseplate material utilance is set, but narrow reinforcement cannot arrange above-mentioned heat conduction limit and complete the heat-conducting effect met the demands.Above-mentioned size can realize balance between the two preferably.
More specifically, described supporting structure can be set to fenestral fabric, is fixedly connected with described reinforcement.The width of described supporting structure can arrange narrow as far as possible thus reduce for the impact when attachment of the jigsaw back side or other process operations.Described supporting structure arranges and can be provided with height adjustable structure thus avoid the impact that mounts the jigsaw back side between reinforcement.
Be understandable that; for those of ordinary skills; can be equal to according to the technical solution of the utility model and the utility model design and replace or change, and all these change or replace the protection range that all should belong to the claim appended by the utility model.
