Abstract
The utility model discloses a wave soldering jig capable of preventing the solder bridge. The wave soldering jig comprises a tray provided with a hollowed part in a shape corresponding to a welding area of a PCB plate. The wave soldering jig is characterized in that a solder drag piece is arranged on the edge of the hollowed part. The solder drag piece is arranged on the edge of the hollowed part of the wave soldering tray jig, thus the continuous welding of welding feet of welding parts is avoided, the probability of poor welding is greatly reduced, and the best welding effect is achieved.
Description
Technical field
The utility model relates to the wiring board production technical field, is specifically related to a kind of anti-Wave soldering fixture that connects tin.
Background technology
As shown in Figure 1, SMT (Surface Mount Technology has generally all been merged in the wiring board production of prior art, surface mount or surface mounting technology) and two kinds of production technologies of wiring board plug-in unit welding, SMT a kind ofly will (be called for short SMC/SMD without pin or short leg surface-assembled components and parts, Chinese title sheet components and parts) be installed in FPC (Flexible Printed Circuit, Flexible Printed Circuit) or PCB (Printed circuit board, printed circuit board) on surface or the surface of other substrate, by the Reflow Soldering method circuit load technology of welding assembly in addition, after partly finishing, SMT again the wiring board plate is carried out the plug-in unit welding, that the welding of FPC plate or pcb board plug-in unit all needs corresponding tool that product to be welded is positioned, can reflow soldering tool and Wave soldering fixture accurately locate welding product, whether sturdy and durable, whether meet environmental requirement, to efficient and the quality important of wiring board production.The Wave soldering fixture of prior art comprises pallet, be provided with on the pallet and the corresponding hollow out of pcb board partial shape to be welded position, pallet carrying pcb board, skim over from the scolding tin surface of Wave soldering furnace, realization is to the welding of part on the pcb board, if the leg of part is more approaching, the phenomenon of weldering easily occurs connecting, particularly the phenomenon of weldering more easily appears connecting in DIP (Dual In-line Package, the integrated circuit (IC) chip of the dual-in-line form encapsulation) pin of part.
The utility model content
The technical problems to be solved in the utility model provides a kind of anti-Wave soldering fixture that connects tin, and the Wave soldering fixture that overcomes prior art can not avoid the soldering part leg to connect the defective of weldering.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to be:
A kind of anti-Wave soldering fixture that connects tin comprises pallet, is provided with on the described pallet and the corresponding hollow out of pcb board welding region shape position, is provided with in the edge at described hollow out position and drags the tin sheet.
The described anti-Wave soldering fixture that connects tin, wherein said dragging on the tin sheet is provided with grid.
The described anti-Wave soldering fixture that connects tin, the vertical bar spacing of wherein said grid is corresponding with the lead pin pitch of DIP part, and the pin of DIP part is stated in described grill frame residence.
The described anti-Wave soldering fixture that connects tin, the wherein said material of tin sheet that drags is made as titanium alloy.
The described anti-Wave soldering fixture that connects tin, the wherein said tin sheet that drags comprises relative titanizing face and sticking tin face, described titanizing face is relative with the bottom surface of described pcb board.
