Abstract
The utility model relates to the producing field of a printed circuit board (PCB), in particular to a fixture special for a PCB hot air solder leveling technology. The fixture comprises a frame capable of adjusting sizes, a clamping groove for clamping the PCB is arranged on the inner lateral wall of the frame, and a fixing hole is arranged on an upper beam of the frame. When in usage, four edges of the PCB are arranged in the clamping groove arranged on the inner side of the frame, and a hot air solder leveling process is conducted after the PCB is fixed, the fact that the PCB transforms, is damaged and the like under influences of pressure of a hot air solder leveling air blade and resistance of solder liquid is effectively avoided, thereby guaranteeing quality of finished boards.
Description
Technical field
The utility model relates to PCB and makes the field, is specifically related to the special fixture in a kind of pcb board tin spray process.
Background technology
In the pcb board manufacturing, for guaranteeing that tin is good on the pcb board, adhesion is strong, producer generally will spray tin to the pcb board surface and handle.But along with the development of technology, electronic product more and more develops to portability, lightening direction, also requires the more lightening densification of its inner wiring board.In traditional tin spray process, single pcb board directly hung on the spray tin hook by the locating hole on it carry out, tin air knife pressure and tin liquor drag effects are sprayed in the pcb board two sides, usually produce the uneven phenomenon of distortion, damage or tin face, not only influence the pcb board outward appearance, and bring serious hidden danger for the scolding tin quality of client, especially for some thin wiring boards, quality problems are more outstanding.
Summary of the invention
The problem that the utility model need solve provides a kind of pcb board spray tin special fixture.
For addressing the above problem, the technical scheme that the utility model is taked is: a kind of pcb board spray tin special fixture, comprise the framework that is used for fixing pcb board, and described frame size is adjustable; This framework comprises interconnective upper beam, underbeam, left side beam, right side beam, described upper beam, underbeam, left side beam, right side beam are formed by the metal tube of the mutual socket of two joints, slide in the metal tube outside by interior metal tube and to adjust the whole size of framework, described in metal tube fix by screw with outer metal tube; Each metal tube is positioned at the inboard place of framework the continuous draw-in groove that is used for the clamping pcb board is set, and on the described upper beam fixing hole is set.
The utility model is simple for structure, and is easy to use; Each beam length of described framework is short all adjustable, can adjust frame size according to the pcb board size during use, side bayonet slot can fixedly secure pcb board in the framework, fixing hole on putting the beams in place by framework hangs on the spray tin hook and sprays the tin operation, can effectively prevent phenomenons such as pcb board distortion, damage, guarantee the production board quality.
Description of drawings
Accompanying drawing 1 is that anchor clamps described in the utility model are formed structural representation;
Accompanying drawing 2 is jig frame girder construction schematic diagrames described in the utility model.
The specific embodiment
For the ease of those skilled in the art's understanding, the utility model structure is further described in detail below in conjunction with accompanying drawing.
As shown in Figure 1, 2, the pcb board spray tin special fixture that the utility model disclosed, primary structure is the framework of an adjustable size, by this framework pcb board is fixed and is sprayed tin again, prevents that plank is because of spraying the distortion that tin air knife pressure and tin liquor drag effects cause.
The size adjustment of this framework is that the length adjustment by four beams forming this framework realizes.Framework is the framework 1 of putting the beams in place 11, underbeam 12, left side beam 13,14 4 beams of right side beam interconnect composition, and each junction can be fixing by welding.Upper beam 11, underbeam 12, left side beam 13, right side beam 14 are formed by the metal tubes of the mutual socket of two joints, and two metal tubes are fixed by the butterfly screw.When need adjusting, screw the butterfly screw, make two metal tubes loosening after, interior metal tube is slided in the metal tube outside, when adjusting to suitable size, tighten the butterfly screw again, frame size is fixed.Be positioned at the inboard place of framework at each metal tube draw-in groove 10 is set, be used for the clamping pcb board, on the upper beam 11 fixing hole is set, be used for articulating with spray tin.
Claims (1)
