Example Embodiment

[0034] In order to fully understand the purpose, features and effects of the present invention, the following specific embodiments are now used in conjunction with the accompanying drawings to give a detailed description of the present invention. The description is as follows:

[0035] Figure 4 to Figure 6 They are respectively an exploded view, a combined view and a top view of the pins, solder and solder pads of a preferred embodiment of the present invention. As shown in the figure, the first aspect of the present invention is a trimming positioning type soldering structure, including multiple A solder pad 3 provided on the circuit board 5 is used to join the SMT electronic component 1 with a plurality of pins 11. The size of the solder pad 3 is larger than the pin 11, and the shape of the pin 11 may be round and The number can be two or more. In the figure, the three-pin 11 is taken as an example. The number of the above-mentioned solder pads 3 corresponds to the number of t...

Abstract

The invention provides a cutting side positioning type welded gasket and a method for preventing pins from shifting, which can prevent a plurality of pins of an electronic component from shifting when the pins of the electronic component are welded on a circuit board. At least two cutting sides are respectively arranged on at least two welding pads of a plurality of welding pads, and the welding pads are arranged on the circuit board and are located at an arranging direction. Thus, with the adoption of the cutting side positioning type welded gasket and the method for preventing the pins from shifting provided by the invention, the processing efficiency can be increased, and the manufacturing cost can be lowered.

Description

technical field [0001] The invention relates to a trimming positioning type welding structure and a method for preventing pin deviation, in particular to a trimming positioning type welding structure in which at least two welding pads of a plurality of welding pads are respectively provided with at least two trimming edges and a method for preventing Method of pin offset. Background technique [0002] Nowadays, the electronic industry is booming, and a large number of electronic devices or products are produced accordingly. Among them, in order to improve the production capacity of electronic devices or products, Surface Mount Technology (SMT) is developed by the industry and added to the manufacturing process. Figure 1 to Figure 3 They are respectively an exploded view and an assembled view of the existing electronic components welded on the circuit board, and a top view of the pins, solder and welding pads when the electronic components are welded on the circuit board. As ...
