When real dress wiring board carries out wave-soldering, because tin furnace temperature and height, the metallic tin of tin stove is liquid, wiring board at the crest place of tin stove through out-of-date, because the absorption affinity of liquid, after through the solder joint of the tin stove liquid tin on the last solder joint of absorption automatically, thereby make last through the too much company's of formation tin phenomenon of liquid tin on two solder joints of tin stove, make that solder joint limit, two places is a conduction path on the wiring board, thereby wiring board becomes unavailable reality dress wiring board.
Usually the settling mode of this kind tin is manual amendment, promptly melts with the metallic tin of flatiron with two solder joint places, connects thereby the tin group at solder joint place is disconnected, and this kind mode must rely on manpower to repair one by one, very waste of manpower and expend a large amount of man-hours.
Be that a kind of settling mode is the improvement to the wave-soldering carrier in addition, the groove design that is about to the real dress of the placement wiring board in the carrier becomes the miter angle rotation tilting, like this, its two avris can become miter angle with molten tin bath when the reality dress wiring board on it was crossed the tin stove, thereby what leave molten tin bath at last is a solder joint, but not two solder joints arranged side by side are beneficial to disengaging liquid tin.Though this kind settling mode makes moderate progress the phenomenon that connects tin but can not stop fully, in addition, the miter angle inclined design of tool makes the material area of tool be multiplied, the material of tool is comparatively expensive at present, will certainly increase production cost, simultaneously, this design also is inconvenient to operate, and causes production efficiency to reduce.
Summary of the invention
The purpose of this utility model is to provide a kind of company of preventing tin tool, and it need not change the angle of the mistake tin stove of real dress wiring board, and cost of manufacture is comparatively cheap, can effectively prevent the company's tin phenomenon in the wave-soldering simultaneously.
The purpose of this utility model is achieved in that a carrier and the thin sheet of metal that it comprises a tool slotted eye and fixes this thin sheet of metal fixture, the described thin sheet of metal device that is fixed is fixed on the avris of carrier, and its free end just extends to carrier slotted eye edge.When the printed board that need go up tin is fixed on the carrier, just parallel the approaching of the limit end of thin sheet of metal connects on the two pin spares of tin on the real dress wiring board easily when crossing the tin stove, the ability that has extremely strong absorption liquid tin because of thin sheet of metal, under the effect of the edge of thin sheet of metal absorption affinity, unnecessary liquid tin will be adsorbed by thin sheet of metal and can not be stranded in solder joint and form to connect tin on the plug-in unit pin, and this kind mode has reduced the flow process of manual amendment circuit board and improved operating efficiency greatly.
