Abstract
The utility model discloses a pre-forming soldering lug which comprises soldering lug body, and a notch for gas inside a soldering lug body to discharge during soldering melting is arranged on the soldering lug body. The notch extends inwards along the outer edge of the soldering lug body and has a wider outside and a narrower inside. The pre-forming soldering lug can save solder flux and improve soldering quality.
Description
Technical field
The utility model relates to preformed soldering, particularly inner bubble-free preformed soldering after a kind of welding.
Background technology
The welding electronic device need to be used scolder on pcb board, fills the alloy material in weld seam when scolder is welding, and moulding in advance, make preformed soldering as required, adopts preformed soldering to carry out various welding, and operation is very easy.But improper or other reason due to control process often has bubble in preformed soldering.After welding, these bubbles still are present in solder side, cause welding quality to descend.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of preformed soldering that can effectively discharge bubble raising welding quality.
For solving the problems of the technologies described above, the utility model is realized by the following technical solutions:
A kind of preformed soldering comprises the weld tabs body, and described weld tabs body is provided with the breach that when melting for welding, weld tabs body interior gas is discharged.
Described breach extends internally along weld tabs body outward flange, and is wide outside and narrow inside.
Preferably, the angle angle of described breach is 5 ℃～30 ℃.
Further preferred, described breach is uniformly distributed in weld tabs body periphery.
Compared with prior art, preformed soldering described in the utility model is provided with breach, can save scolder, can reach again the rear effect of discharging air entrapment of welding, improves welding quality.
Description of drawings
Fig. 1, the 2nd, the top view of a kind of structure of preformed soldering embodiment described in the utility model and front view;
Fig. 3, the 4th, the top view of the another kind of structure of preformed soldering embodiment described in the utility model and front view;
Fig. 5, the 6th, the top view of the third structure of preformed soldering embodiment described in the utility model and front view.
The specific embodiment
For the ease of those skilled in the art's understanding, below in conjunction with specific embodiment and accompanying drawing, the utility model theory of constitution is further described in detail:
As shown in Figure 1, 2, top view and the front view of a kind of cuboid preformed soldering structure that discloses for the utility model, four limits of the upper surface of cuboid preformed soldering evenly are provided with some breach wide outside and narrow inside.
As shown in Fig. 3,4, top view and the front view of a kind of frame type preformed soldering structure that discloses for the utility model, outward flange four limits of the upper surface of frame type preformed soldering evenly are provided with some breach wide outside and narrow inside.
As shown in Fig. 5,6, top view and the front view of the preformed soldering structure of a kind of cylindrical tube shape that discloses for the utility model, the outward flange of the upper surface of the preformed soldering of cylindrical tube shape evenly is provided with some breach wide outside and narrow inside.
The preformed soldering of the above three kinds of shape, when welding was melted, internal gas was discharged by described breach, and welding quality is higher.
Need to prove, not breaking away under the utility model design prerequisite its any minor variations of doing and being equal to replacement, all should belong to protection domain of the present utility model.
Claims (4)
1. a preformed soldering, comprise the weld tabs body, it is characterized in that: described weld tabs body is provided with the breach that when melting for welding, weld tabs body interior gas is discharged.
