Description

A kind of jig fixing frame

Technical field

The present invention relates to a kind of jig fixing frame that is used for the wiring board electroplating work procedure.

Background technology

Must be when producing circuit card through one galvanized operation, electric current conducts in the wiring board by flying target.Usually, the jig fixing frame that adopts during plating all adopts the metallic conductor manufacturing.But this method can produce a drawback, promptly makes at lower frame and hang on the arm also can plated with copper, and this phenomenon can make electric current can not 100% act on the wiring board, causes excess loss.And, cause wiring board thin partially, became uneven near the copper that is plated on the zone of frame because lower frame has disperseed electric current.

Summary of the invention

Technical problem to be solved by this invention provide a kind of can be on fixed frame copper-plated jig fixing frame.

The object of the present invention is achieved like this:

A kind of jig fixing frame comprises at least one extension arm that vertically extends that lower frame and bottom and this lower frame are fixedly connected, and described lower frame is provided with the lower clamp that is used for the described wiring board of clamping.At least a portion of described lower clamp adopts the isolator manufacturing, and the part of described employing isolator manufacturing comprises all and the direct contacted surface of described wiring board, is fixedly connected described extension arm and described lower frame mutually insulated.

Described lower frame is an at least one transverse slat, on the side surface of the bottom of described extension arm, be welded with a metallic interconnect, on described web plate, offer the through hole that passes for threaded connector, on described transverse slat, offer the threaded hole that matches with described threaded connector, described web plate parallels with at least one described transverse slat and is fixedly connected by described threaded connector, all is being folded with insulating trip between described web plate and the described threaded connector and between described web plate and the described transverse slat.On the inwall of described through hole, be fixed with insulation covering.Described lower frame is discrete plural piece transverse slat, and the both side ends of every described web plate is fixedly connected with adjacent two described transverse slats respectively.

Upper end at described extension arm is set with metal hanger, mutually insulated between this hook and the described extension arm.Upper end at described extension arm is welded with metal connecting sheet, on described hook, offer the through hole that passes for threaded connector, described connection piece and described hook are fixedly connected by described threaded connector, between described connection piece and described hook, be folded with insulating trip, on the inwall of described through hole, be set with insulation covering.

Described lower clamp is the discontinuous plurality of points clamp device that is fixedly installed on the described lower frame.Described point clamps and is changed to polypropylene material matter.

Because the utilization of technique scheme, the present invention has avoided copper facing on fixed frame, can not only avoid the excess loss of electric current, improves electroplating efficiency, and the consumption of also having saved copper ball has all reduced cost from two aspects.

Embodiment

Below in conjunction with accompanying drawing embodiments of the present invention are specifically described.

As shown in Figure 1, according to jig fixing frame of the invention process, constitute by lower frame 1 and extension arm 2.The upper end that hangs arm 2 is provided with hook 10, is used for whole fixed frame is fixed on flying target.Hanging the bottom of arm 2 and lower frame 1 is fixedly connected by threaded connector.

Accompanying drawing 2 is at the extension arm 2 of anchor end and the syndeton synoptic diagram between the lower frame 1.Lower frame 1 is made of the transverse slat 4 of polylith along horizontal expansion, hangs arm 2 and then is welded on the web plate 5 of a metal material.With web plate 5 and fixedlying connected that transverse slat 4 parallels, and folder is established an insulating trip 6 between these two parts with bolt 7.Between the head of bolt 7 and web plate 5, also be folded with insulating trip 6, and on the inwall that is opened in the through hole 8 on the web plate 5, fixedly install a circle insulation covering 9, so just will realize insulation between web plate 5 and transverse slat 4 and web plate 5 and the bolt 7.

Insulating trip 6 all adopts the plastics manufacturing with insulation covering 9.In use fixed frame need be immersed in the nitric acid soup with severe corrosive, is used to remove the copper that is plated on frame and the last anchor clamps.Therefore insulating trip 6 and insulation covering 9 also must be corrosion-resistant.Simultaneously, owing to take bolt 7 to realize fixing, stressed bigger, therefore also must select the enough materials of rigidity, prevent distortion.Therefore can select for use polypropylene to make insulating trip 6 herein, select for use tetrafluoroethylene to make insulation covering 9.

Accompanying drawing 3 is for being fixed in extension arm 2 in the middle part of the fixed frame and the syndeton synoptic diagram between the lower frame 1.About be discontinuous between two adjacent transverse slats 4, and the both ends, the left and right sides of web plate 5 are fixedly connected with two transverse slats 4 respectively.This syndeton is more more firm, not yielding than adopting a monoblock successive transverse slat 4.

Different with the syndeton shown in the accompanying drawing 2, this syndeton also accompanies two cushion blocks 12 between web plate 5 and transverse slat 4, and its effect is to regulate the spacing of hanging between arm 2 and the lower frame 1.Between transverse slat 4 and the cushion block 12 by insulating trip 6 mutually insulateds, thereby indirect realization and web plate 5 between insulation.Between bolt 7 and insulating trip 6, also be folded with compression spring 13.

Shown in the accompanying drawing 4 is the syndeton of hanging between arm 2 and the hook 10.Hang arm 2 and be welded on the connection piece 11 of metal material, connection piece 11 then is fixedly connected by bolt 7 and hook 10.Between connection piece 11 and the hook 10, nut 14 with link up with 10 between all be folded with insulating trip 6, be set with insulation covering 9 being used to hold on through hole 8 inwalls of bolt 7.This structure has realized linking up with 10 and has been connected with the insulation of hanging between the arm 2, and electric current just can not conduct to and hangs on the arm 2 from flying target like this, therefore passes through with regard to not having electric current on extension arm 2, can copper facing yet.

The lower clamp that is fixedly installed on the lower frame 1 is a plurality of somes clamp devices 3.Adopt the mode of some folder to replace traditional strip clamping, the wiring board of not only having avoided the clamp bar distortion to cause is fixing not firm, can effectively avoid liquid medicine to remain between lower clamp and the wiring board yet, helps to improve the quality of wiring board.

Point clamp device 3 adopts the acrylic resin manufacturings, not only realized and wiring board between insulation, and corrosion-resistant, can put into strong acid soaks, in order to divest the copper that is plated on the anchor clamps.

As mentioned above, we are illustrated according to aim of the present invention fully, but the present invention is not limited to the foregoing description and implementation method.The practitioner of correlative technology field can carry out different variations and enforcement in the scope of technological thought permission of the present invention.
