Abstract
The utility model discloses a fixing clamp for electroplating a printed circuit board (PCB). The fixing clamp comprises a first clamping plate and a second clamping plate which are oppositely arranged, wherein the first clamping plate and the second clamping plate are fixed at opposite positions; a slit for clamping the PCB to be electroplated is formed between the first clamping plate and the second clamping plate; a lock element can penetrate through the first clamping plate and can be positioned in the slit in a manner of moving back and forth opposite to the second clamping plate; a bump which protrudes on the side surface is arranged at the side surface of the second clamping plate towards the first clamping plate in a positioning manner; the bump is arranged corresponding to the lock element in a matching manner, so that the contact area between the second clamping plate and the PCB to be electroplated is reduced; the phenomenon that a PCB pattern is covered due to a narrow border of the PCB is avoided; the rejection rate of the PCB is greatly reduced.
Description
Technical field
The utility model relates to the printed circuit board technical field, specifically provides a kind of pcb board to electroplate and uses stationary fixture.
Background technology
In the pcb board electroplating technology; need to use fixture and clamp the electroplated pcb board; but when processing the narrower pcb board of some pcb board frames; because the contact surface between existing fixture and pcb board is larger; careless slightly during employee's upper plate; will easily cause on fixture the clamping plate that are positioned at back side to hide on the circuit of pcb board effective area; and then pcb board makes the circuit in effective area not plate protective layer because of blocking of fixture; etched away by meeting when etching like this, finally cause scrapping of pcb board.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides a kind of pcb board to electroplate and has used stationary fixture, and this fixing jig structure is simple, can effectively avoid, because of the narrower phenomenon that the pcb board figure is covered of pcb board frame, greatly reducing the condemnation factor of pcb board.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of pcb board is electroplated and is used stationary fixture, this stationary fixture comprises and is the first clamping plate and the second clamping plate that are oppositely arranged, described the first clamping plate and the second clamping plate relative position are fixed, and be formed with one between described the first clamping plate and the second clamping plate for the cracking of clamping electroplated pcb board, locking part can wear described the first clamping plate and in cracking relatively described the second clamping plate do to move around location; Also at described the second clamping plate, on a side surface of described the first clamping plate, locate and be provided with a projection that protrudes from this side surface, and described projection and described locking part coordinate corresponding setting.
As further improvement of the utility model, described the first clamping plate and the fixing structure of the second clamping plate relative position are: also be provided with a plurality of guide pillars, the plurality of guide pillar interval is fixedly arranged between described the first clamping plate and the second clamping plate.
As further improvement of the utility model, locking part can wear described the first clamping plate and in cracking relatively described the second clamping plate do to move around structure of location be: described locking part is lock screw, another offer a pilot hole worn for described lock screw on described the first clamping plate, and on the inner side-wall of described pilot hole, be formed with described lock screw on the internal thread segment that is complementary of external thread section.
The beneficial effects of the utility model are: by location on the second clamping plate, be provided with a cylindrical protrusions, thereby reduced the contact area between the second clamping plate and electroplated pcb board, avoided, because of the narrower phenomenon that the pcb board figure is covered of pcb board frame, greatly reducing the condemnation factor of pcb board.
The accompanying drawing explanation
Fig. 1 is that in prior art, pcb board is electroplated the structural representation with stationary fixture;
Fig. 2 is that in the utility model, pcb board is electroplated the structural representation with stationary fixture.
By reference to the accompanying drawings, make the following instructions:
1---first clamping plate 2---second clamping plate
20---projection 3---locking part
4---guide pillar
Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
A kind of pcb board provided by the utility model is electroplated and is used stationary fixture, this stationary fixture comprises before and after being the first clamping plate 1 and the second clamping plate 2 that are oppositely arranged, described the first clamping plate 1 and the second clamping plate 2 relative positions are fixed, and be formed with one between described the first clamping plate and the second clamping plate for the cracking of clamping electroplated pcb board, locking part 3 can wear described the first clamping plate 1 and in cracking relatively described the second clamping plate 2 do to move around location; Also at described the second clamping plate 2, on a side surface of described the first clamping plate, locate and be provided with a cylindrical protrusions 20 that protrudes from this side surface, and described protruding 20 coordinate corresponding setting with described locking part 3.By at the second clamping plate 2, on a side of the first clamping plate, locating and be provided with a cylindrical protrusions 20, reduced the contact area between the second clamping plate and band plating pcb board, avoided, because of the narrower phenomenon that the pcb board figure is covered of pcb board frame, greatly reducing the condemnation factor of pcb board.
In the present embodiment, described the first clamping plate 1 and the fixing structure of the second clamping plate 2 relative positions are: also be provided with a plurality of guide pillars 4, the plurality of guide pillar 4 intervals are fixedly arranged between described the first clamping plate and the second clamping plate.
In the present embodiment, locking part 3 can wear described the first clamping plate 1 and in cracking relatively described the second clamping plate 2 do to move around structure of location be: described locking part is lock screw (or bolt), another offer a pilot hole worn for described lock screw on described the first clamping plate 1, and on the inner side-wall of described pilot hole, be formed with described lock screw on the internal thread segment that is complementary of external thread section.
