What are the requirements of lithium battery circuit board processing manufacturers for the assembly of PACK lithium battery packs

1. The polarity of the nickel strip pad and the polarity of the nearby components cannot be exactly opposite, otherwise it is easy to cause a short circuit due to the operation of the staff during the process of soldering the nickel strip. 2. The position of the pad and the reed of the nickel strip should not be exactly opposite, otherwise the solder of the reed terminal will melt due to the temperature of the electric soldering iron during the process of soldering the nickel strip, and the reed will easily fall off later. 3. The size of the pads of the nickel strip and the reed should be set according to the nickel strip and the reed, and the size of the pad should be relatively large so that it is not easy to cause false soldering. 4. The spacing between the reed pads should be as large as possible, because tin and solder paste can easily cause micro-shorts between the pins. If the spacing cannot be changed, a tin-barrier wire should be set between them. 5. The gold plating thickness of the reed should be detectable through oxidation and wear resistance, generally 10 microns. 6. The thickness of the COB board is better than that of the PWB board. The important thing is that the wiring is very thin, and the thick circuit board is not easy to be deformed by external forces, so as to play a protective role. 7. When the lithium battery circuit board is located on the side of the battery cell, try to put the B- terminal close to the B- of the battery cell, and beware of the excessively long negative nickel strip, which may cause a lot of unnecessary trouble.
