Abstract
The utility model relates to a circuit board mounting tool. The circuit board mounting tool comprises a carrier board, wherein the carrier board closely clings to a lower surface of a circuit board, a face of the carrier board which opposes to the circuit board is provided with at least one blind groove, the blind grooves are partially or completely provided with corresponding strong magnetic materials having same polarities, and an upper surface of the circuit board corresponding to positions of the strong magnetic materials in the blind grooves is provided with strong magnetic materials. According to the circuit board mounting tool, the strong magnetic materials are utilized to fix the circuit board on the carrier board, so the circuit board having weak rigidity can be better supported, denting or other shape deformation of the circuit board in an SMT (surface mount technology) process can be avoided, and thereby circuit board mounting can be better carried out.
Description
Technical field
The utility model relates to the wiring board tool of production, particularly relates to a kind of wiring board patch jig.
Background technology
Along with electronic product to high density, miniaturization, high reliability future development, people more and more need a kind ofly can provide good electrical property, can meet the more small-sized and circuit board of the design of high-density installation more, the PCB(printed circuit board (PCB) that rigidity is weak) or the FPC(flexible printed circuit board) can free bend, folding, can bear the dynamic bending of millions of times and not damage wire, can require to arrange arbitrarily according to space layout, greatly dwindle the volume of electronics finished product, met people's needs.
The general employing of chip mounter can be adjusted the Guide Rail Design of width automatically, and in the time of paster, the contact point of wiring board and chip mounter only has the guide rail of both sides and chip mounter.When a little less than the PCB rigidity or during FPC, SMT(electronic circuit surface installation technique) in process, PCB or FPC pars intermedia branch fall in, and affect the paster quality.In prior art, the general thimble that adopts is propped up the centre of wiring board come, but, for the PCB that does not have rigidity or FPC, effect is very undesirable.
The utility model content
Based on this, be necessary for the problems referred to above, a kind of wiring board patch jig is provided.
A kind of wiring board patch jig, comprise support plate, described support plate is close to the wiring board lower surface, described support plate is provided with at least one blind slot back to the one side of wiring board, each described part blind slot or all in blind slot, be provided with corresponding polarity ferromagnetic material in the same way, and the wiring board upper surface is provided with ferromagnetic material corresponding to the position of ferromagnetic material in described blind slot.
Above-mentioned wiring board patch jig, use described magnetic material that wiring board is fixed on described support plate, can better support the very weak PCB of rigidity or FPC, make the SMT process of the very weak PCB of rigidity or FPC the distortion of dented or other shape can not occur, thus better paster; Use ferromagnetic material to fix wiring board, the wiring board upper and lower plates is convenient, and can reuse, and makes the range of application of support plate wider simultaneously, and dissimilar wiring board all can be used same support plate to be processed.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model embodiment;
Fig. 2 is the utility model support plate and blind slot front elevational schematic.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
As shown in Figure 1, a kind of wiring board patch jig, comprise support plate 1, described support plate 1 is close to wiring board 4 lower surfaces, described support plate 1 is provided with at least one blind slot 2 back to the one side of wiring board 4, each described part blind slot 2 or all in blind slot 2, be provided with corresponding polarity ferromagnetic material 3 in the same way, and wiring board 4 upper surfaces are provided with ferromagnetic material 3 corresponding to the position of the interior ferromagnetic material 3 of described blind slot 2.
Wherein said wiring board 4 is mainly the very weak PCB of rigidity or FPC.
In a specific embodiment, the one side that described support plate 1 is close to wiring board 4 can also be provided with location hole, and described support plate 1, by the position of described location hole location wiring board 4, is fixed on described support plate 1 wiring board 4 faster and more easily.Support plate 1 described in the utility model embodiment is by loading onto at described location hole the position that suitable pin is located wiring board 4.
In a specific embodiment, described wiring board 4 is at least one, the size of described support plate 1 can be determined according to the size and number of the wiring board 4 that will place, the size of described support plate 1 is more than or equal to described wiring board 4 sizes, better described wiring board 4 is supported, make the middle distortion that depression or other situation do not occur of SMT process of described wiring board 4.
In a specific embodiment, described support plate 1 can, for rigidity is strong and density circlet oxygen plate or similar substrate, make it have enough rigidity smaller to described wiring board 4 supports and weight own.1 thickness of support plate described in the present embodiment is preferably 2.0mm-3.0mm.General in the situation that cost is suitable preferentially selects strong, the low density material of rigidity, in the situation that material stiffness enough the thickness of described support plate 1 can be thinner.
In a specific embodiment, as shown in Figure 2, the degree of depth of described blind slot 2 is less than the thickness of described support plate 1, is greater than the thickness of described ferromagnetic material 3, and the degree of depth of the described blind slot 2 of the present embodiment is preferably more than and equals 1.5mm, is less than 2.0mm.Described blind slot 2 size and shapes and described ferromagnetic material 3 couplings.
In a specific embodiment, described blind slot 2 can be with array-like or circular-arc or concentric circles or the arrangement of other irregular shape.
In a specific embodiment, the described ferromagnetic material 3 on described wiring board 4 is at least three, because at least use three groups of corresponding ferromagnetic materials 3 better to fix wiring board 4, it is not rotated or move, and reaches paster effect preferably.
In a specific embodiment, described ferromagnetic material 3 is strong magnetic piece or strong magnetic stripe.
Above-mentioned wiring board patch jig, the PCB that 1 pair of rigidity of described support plate is very weak or FPC support, and Area of bearing is large, makes it that distortion of intermediate recess or other shapes not occur in the SMT process; At least use three groups of ferromagnetic materials 3 up and down wiring board 4 to be fixed, make wiring board 4 not move or rotate in the paster process, reach paster effect preferably, and wiring board 4 upper and lower plates are convenient, can reuse, dissimilar wiring board 4 all can be used same support plate 1 to be processed simultaneously, makes the range of application of support plate 1 wider.
The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
