Technical Field

The utility model belongs to the technical field of the PCB tool, specific theory relates to a wave-soldering tool.

Background

Wave soldering refers to the soldering of mechanically and electrically connecting the soldering terminal or pin of a component and the pad of a printed board by injecting nitrogen into a solder bath, wherein molten soft solder (tin alloy) is sprayed into the solder wave required by design by an electric pump or an electromagnetic pump, and the solder wave is also formed by injecting nitrogen into the solder bath, so that the printed board with the component mounted in advance passes through the solder wave.

In the wave soldering process of the PCB, a jig is needed to be used as a carrier, so that the solder is only contacted with the position needing soldering.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the following will explain in detail a preferred embodiment of the present invention with reference to the accompanying drawings to facilitate understanding of the skilled person.

As shown in the figure, the wave soldering jig comprises a bottom plate 1; bottom plate 1 include connecting portion 2, components and parts supporting part 3, connecting portion 2 is used for making the PCB board be connected with the tool, there is elasticity preforming 5 in the supporting part through the screw connection, elasticity preforming 5 has three, there are two on 3 left sides of components and parts supporting part, there is a slice in 3 rear sides of components and parts supporting part, in use, place PCB on bottom plate 1, can place a PCB board, also can place polylith PCB board simultaneously, be applicable to the PCB board of different shapes simultaneously, application scope is extensive, adopt elasticity preforming 5 to push down the PCB board, make the firm fixing of PCB board on bottom plate 1, it leads to the welding insecure to avoid the PCB board to take place to remove at the wave-soldering in-process. Connecting portion 2 encircles around component bearing part 3, and component bearing part 3 is close to right-hand member face department and is equipped with whole briquetting 9, and whole briquetting 9 is used for pushing down the components and parts of easy perk, makes the components and parts that need the welding can not perk in welding process and drops, guarantees that wave-soldering goes on steadily. Be equipped with on the components and parts bearing part 3 and make the PCB board weld the inlayed recess 6 of components and parts, the position and the size of recess 6 and weld the components and parts position and size phase-match on the PCB board, place the PCB board back on bottom plate 1, in welded components and parts inlayed recess 6 on the PCB board, make the PCB board can tile on bottom plate 1, simultaneously, play the positioning action to the PCB board, make the PCB board fix in needs position. The component bearing part 3 is provided with a through hole 7 through which a pin of a component packaged by the DIP can pass, and the pin of the component is exposed out of the lower surface of the bottom plate 1 from the through hole 7, so that wave soldering is facilitated.

Both ends are equipped with the guard plate 8 that is used for protecting the PCB board around bottom plate 1, effectively prevent that the PCB board from colliding with other objects and damaging. The left end and the right end of the bottom plate 1 are respectively connected with the auxiliary plates 4 through screws, so that the transportation jig is convenient to lift.

The utility model discloses the working process: the PCB is placed on the jig bottom plate 1, components welded on the PCB are embedded in the grooves, then the PCB is pressed by the elastic pressing sheets 5, the PCB is fixed at the corresponding position of the jig, the auxiliary plate 4 is held by a hand to lift the jig, and the jig is placed in the wave soldering equipment.

Finally, it is noted that the above preferred embodiments illustrate rather than limit the invention, and that, although the invention has been described in detail with reference to the above preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the invention as defined by the appended claims; the size of the attached figure is irrelevant to the specific real object, and the size of the real object can be changed at will.
