Welding structure of lithium battery and circuit board and welding method

Abstract

The invention provides a welding structure of a lithium battery and a circuit board and a welding method. The welding method includes the lithium battery provided with a positive plate and the negative plate; a first positive electrode welding part is arranged on the positive board and a second positive electrode welding part connected to the first positive electrode welding part; a first negative electrode welding part arranged on the negative plate and a second negative electrode welding part connected to the first negative electrode welding part; the circuit board including a positive electrode pad and a negative electrode pad; a first positive electrode welding area arranged on the positive electrode pad and a second positive electrode welding area connected to the first positive electrode welding area; a first negative electrode welding area arranged on the negative electrode pad and a second negative electrode welding area connected to the first negative electrode welding area. The first positive electrode welding part is welded on the first positive electrode welding area and a first negative electrode welding area is welded on the first negative electrode welding area.

Description

technical field [0001] The invention relates to a welding structure and a welding method, in particular to a welding structure and a welding method of a lithium battery and a circuit board. Background technique [0002] With the rapid development of science, many portable electronic devices are not only becoming thinner, thinner and smaller, but also have more and more complex functions, so the requirements for battery life are also getting higher and higher. Especially in recent years, smart phones and tablet computers have become a sales whirlwind in the 3C consumer electronics market, and have almost become indispensable electronic products in modern people's lives. [0003] With the active investment and research and development of software and hardware manufacturers, the boundaries between mobile phones and so-called computers have become increasingly blurred, especially the highly portable smart mobile phones and tablet computers, which can be said to have capabilities...

AI Technical Summary

Problems solved by technology

[0006] In view of this, the object of the present invention is to provide a welding structure and welding method for a lithium battery and a circuit board, which can overcome the problem that both of the existing lithium battery and the circuit board are scrapped at the same time and cannot be reworked when one of them is defective.
