Description
本發明係一種銲接結構與銲接方法，特別是一種鋰電池與電路板的銲接結構與銲接方法。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.
科學發展一日千里，許多攜帶式電子設備不僅日益輕薄短小，且具有的功能也愈來愈複雜，因而對電池的續航力要求也愈來愈高。尤其近年來智慧型手機與平板電腦已在3C消費電子市場颳起一陣銷售旋風，幾乎已成為現代人生活中不可或缺的電子產品。With the rapid development of science, many portable electronic devices are not only increasingly thin and light, but also have more and more complex functions, so the battery life requirements are getting higher and higher. In particular, in recent years, smart phones and tablet PCs have ignited a whirlwind of sales in the 3C consumer electronics market, and have become an indispensable electronic product in modern life.
隨著軟硬體廠商的積極投入與研發，行動電話與所謂電腦的界限早已日益模糊，特別是具有高度可攜性的智慧型行動電話與平板電腦，其可說已具有可與桌上型電腦相媲美的功能。也由於智慧型手機與平板電腦的功能相當強大，因此其主機板必須內建各種高效能的昂貴電子元件，同時其所使用的鋰電池也必須使用較高規格的產品。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 smart mobile phones and tablets with high portability, which can be said to have a desktop computer. Comparable to the features. Because smart phones and tablets are quite powerful, their motherboards must have built-in high-performance and expensive electronic components, and the lithium batteries used must also use higher-standard products.
為了減少攜帶式電子設備的體積，目前已有業者直接將鋰電池以銲接(例如：點銲阻抗熔接、超音波、雷射點銲與導通介值熔接型式之電銲等)的方式銜接於主機板上，亦即鋰電池從原先的可拆卸式改為不可拆卸式，而係直接內建於攜帶式電子設備中。惟，此種方式固然可減少攜帶式電子設備的體積，但一旦銜接過程中發生製程缺陷，例如鋰電池或主機板發生缺陷，則依照傳統的設計並無法重工，導致鋰電池與主機板必須同時報廢。又或者，倘若客戶送交有瑕疵的產品回廠檢修，經檢測後發現僅僅是鋰電池或主機板的其中一者發生缺陷，此時也會囿於傳統的製造方式並無法重工，而導致鋰電池與主機板必須同時報廢。In order to reduce the size of portable electronic devices, the lithium battery has been directly connected to the motherboard by soldering (for example, spot welding, ultrasonic welding, laser spot welding, and conduction bonding type welding). The lithium battery is changed from the original detachable type to the non-detachable type, and is directly built in the portable electronic device. However, this method can reduce the size of the portable electronic device. However, if a process defect occurs during the connection process, such as a defect in the lithium battery or the motherboard, the conventional design cannot be reworked, and the lithium battery and the motherboard must be simultaneously scrapped. Or, if the customer sends the defective product back to the factory for repair, it is found that only one of the lithium battery or the motherboard has a defect, and at this time, it will be in the traditional manufacturing mode and cannot be reworked, resulting in lithium battery. The pool and the motherboard must be scrapped at the same time.
因此，習知技術具有無法重工，導致生產成本提高的問題。Therefore, the conventional technology has a problem that it is impossible to rework, resulting in an increase in production cost.
有鑑於此，本發明提出一種鋰電池與電路板的銲接方法，包含：提供鋰電池，其包含正極板與負極板；於正極板配置第一正極銲接部與連接於第一正極銲接部之第二正極銲接部；於負極板配置第一負極銲接部及連接於第一負極銲接部之第二負極銲接部；提供電路板，其包含正極焊墊與負極焊墊；於正極焊墊配置第一正極銲接區與連接於第一正極銲接區之第二正極銲接區；於負極焊墊配置第一負極銲接區及連接於該第一負極銲接區之第二負極銲接區；銲接第一正極銲接部於第一正極銲接區；及銲接第一負極銲接部於第一負極銲接區。In view of the above, the present invention provides a method for soldering a lithium battery and a circuit board, comprising: providing a lithium battery including a positive electrode plate and a negative electrode plate; and disposing the first positive electrode welded portion and the first positive electrode welded portion on the positive electrode plate a second positive electrode welded portion; a first negative electrode welded portion and a second negative electrode welded portion connected to the first negative electrode welded portion are disposed on the negative electrode plate; a circuit board including a positive electrode pad and a negative electrode pad; and a positive electrode pad disposed first a positive electrode bonding region and a second positive electrode bonding region connected to the first positive electrode bonding region; a first negative electrode bonding region and a second negative electrode bonding region connected to the first negative electrode bonding region; and a first positive electrode bonding portion In the first positive electrode bonding zone; and welding the first negative electrode bonding portion to the first negative electrode bonding zone.
此外，本發明亦提出一種鋰電池與電路板的銲接結構，包含鋰電池與電路板。其中，一鋰電池包含正極板與負極板，正極板包含第一正極銲接部與第二正極銲接部，第二正極銲接部連接於第一正極銲接部。電路板包含正極焊墊與負極焊墊，正極焊墊包含第一正極銲接區與第二正極銲接區，第二正極銲接區連接於第一正極銲接區。前述第一正極銲接部係銲接於第一正極銲接區，第一負極銲接部係銲接於第一負極銲接區。In addition, the present invention also provides a soldering structure of a lithium battery and a circuit board, including a lithium battery and a circuit board. The lithium battery includes a positive electrode plate and a negative electrode plate. The positive electrode plate includes a first positive electrode welded portion and a second positive electrode welded portion, and the second positive electrode welded portion is connected to the first positive electrode welded portion. The circuit board comprises a positive electrode pad and a negative electrode pad, the positive electrode pad comprises a first positive electrode pad and a second positive electrode pad, and the second positive electrode pad is connected to the first positive electrode pad. The first positive electrode welded portion is welded to the first positive electrode welding portion, and the first negative electrode welded portion is welded to the first negative electrode welded portion.
因此，當鋰電池發生缺陷時，只要移除並分離正極板之第一正極銲接部與負極板之第一負極銲接部，使鋰電池與電路板分離，然後再分別銲接另一鋰電池之第二正極銲接部與第二負極銲接部於電路板之第二正極銲接區與第二負極銲接區，便可達到重工的目的，而不需要將鋰電池與電路板一起報廢。Therefore, when a defect occurs in the lithium battery, the first positive electrode welded portion of the positive electrode plate and the first negative electrode welded portion of the negative electrode plate are removed and separated, the lithium battery is separated from the circuit board, and then the second lithium battery is separately soldered. The positive electrode welding portion and the second negative electrode welding portion are in the second positive electrode bonding zone and the second negative electrode bonding region of the circuit board, so that the purpose of rework can be achieved without the lithium battery being scrapped together with the circuit board.
此外，在一種實施態樣中，係將多個鋰電池以串/並聯的方式電性連接於電路板，當鋰電池發生缺陷時，只要移除發生缺陷之鋰電池之正極板之第一正極銲接部與負極板之第一負極銲接部，使發生缺陷之鋰電池與電路板分離，然後再分別銲接另一鋰電池之第二正極銲接部與第二負極銲接部於電路板之第二正極銲接區與第二負極銲接區，便可達到重工的目的，而不需將多個鋰電池連同電路板一起報廢。In addition, in one embodiment, a plurality of lithium batteries are electrically connected to the circuit board in a series/parallel manner, and when the lithium battery is defective, the first positive electrode of the positive electrode plate of the defective lithium battery is removed. And the first negative electrode welding portion of the negative electrode plate separates the defective lithium battery from the circuit board, and then separately solders the second positive electrode welding portion and the second negative electrode welding portion of the other lithium battery to the second positive electrode bonding portion of the circuit board With the second negative electrode bonding area, the purpose of rework can be achieved without having to scrape a plurality of lithium batteries together with the circuit board.
同樣地，當發生缺陷的是電路板時，只要移除並分離正極板之第一正極銲接部與負極板之第一負極銲接部，使電路板與鋰電池分離，然後再將原鋰電池之第二正極銲接部與第二負極銲接部分別銲接於另一電路板之第二正極銲接區與第二負極銲接區，即可達到重工的目的，而不需要將鋰電池與電路板一起報廢。Similarly, when the defect occurs in the circuit board, the first positive electrode soldering portion of the positive electrode plate and the first negative electrode soldering portion of the negative electrode plate are removed and separated, so that the circuit board is separated from the lithium battery, and then the first lithium battery is replaced. The second positive electrode welding portion and the second negative electrode welding portion are respectively soldered to the second positive electrode bonding portion and the second negative electrode bonding portion of the other circuit board, so that the purpose of rework can be achieved without the lithium battery being scrapped together with the circuit board.
因此，本發明可解決習知技術所具有之無法重工，導致生產成本提高的問題。Therefore, the present invention can solve the problem that the conventional technology cannot be reworked, resulting in an increase in production cost.
