Embodiment 1

[0016] image 3 Shown is one of the embodiments of the present invention, when the circuit board is arranged in element layout, if a large-area pad is required for the spot welding component, the pad at the spot welding position is designed as a lead-out shape, that is, the pad at the spot welding position According to the spot welding process specification, a pad 1' is drawn from the large-area copper clad to make it the same size as pads 2 and 3, and at the same time, it is arranged neatly adjacent to meet the requirements of component layout and the purpose of simplifying the welding process. , At the same time, it is more conducive to the layout of components on the circuit board due to the division into parts.

Embodiment 2

[0018] Figure 5 Shown is one of the embodiments of the invention, with Figure 4 In terms of the previously shown spot welding circuit board layout design, the pad 4 at the spot welding position is designed as a hollow form. like Figure 5 As shown, that is, a pad 4 ′ is dug out on a large-area copper clad to make it the same size as the pad 5 . Its use effect is the same as that of leading form.

Abstract

The pad spot welding method includes optimizing pad layout in circuit board and regulating the area of the pads to be spot welded for the same size. Specifically, the area of the pads may be regulated through leading out and carving in unifying the area of pads. In this way, the welding parameters, including welding pressure, output voltage, pulse width, etc. need no frequent regulation during welding, to facilitate welding and to raise welding efficiency and quality.

Description

technical field [0001] The invention relates to a welding method, in particular to a pad spot welding method. Background technique [0002] Most of the currently used SW spot welding, SW is taken from the first letter of the English "STRIPPING" (paint removal) and "WELDING" (welding), which means that the SW electronic spot welding machine can directly weld the enameled wire without removing the insulating paint in advance. function. Its basic working principle is that spot welding is a welding in which a strong current passes through two point electrodes (including parallel electrodes) that are pressed and overlapped in a short period of time to form solder joints under resistance heat and pressure. Its specific operation method is as figure 1 As shown, when welding on the circuit board 6, the SW electronic spot welder sets three groups of parameters of welding pressure F, output pulse amplitude (Voltage) and pulse width (Millisecond) according to the wire diameter of the...
