Lithium battery tin welding connection.12v 100ah lithium ion battery

　　Main principles: Use the soldering iron heat to melt the welding wire, so that the tin is attached to the welded area, and it is connected after cooling.

　　1) The soldering iron classification:

　　A. Internal thermal and external thermal type, internal thermal soldering iron increases fast.

　　B. Ordinary soldering iron, temperature adjustment iron, anti -static constant temperature soldering iron.

　　2) The power of the soldering iron: 30W, 35W, 40W, 50W, 55W, 60W, 65W, etc.

　　3) The temperature of the soldering iron: According to the weld area and the amount of tin, the temperature cannot melt the tin line quickly, affect the welding speed, the temperature is too high, and the solder point is not smooth. The temperature of the soldering iron is generally set at 360 ℃ ± 10 ℃

　　4) Welding attitude: generous and natural, sitting right.

　　5) Welding method: There is a grip and a direct grip.

　　6) Welding angle: The welding angle of the hand grip method is between 30 ° and 60 °. The best angle is the tip of the soldering iron and the welding body to 45 °.

　　7) Welded ingredients: tin (SN) 60 ~ 63%, lead (PB) 40 ~ 37%, rosin 1.0%~ 1.2%of existing companies began to use lead -free welded

　　8) Welding time: <3s

　　9) Method: First put the soldering iron on the welding part, and then put the tin line on the gap between the soldering iron head and the welding site.

　　10) Welded: It can be wrapped in an appropriate amount of welded body tinnus.

　　11) Welding quality: The welds are bright and uniform, firm, without linked tin, leakage welding, no false welding, no pores, no layers. The size of the solder joint is related to the amount of contact with the heat tin;
