What are the requirements for lithium battery protection board for lithium battery PACK assembly

When assembling a small PACK lithium battery pack, the lithium battery protection board is an indispensable accessory. The protection board must be used carefully during the PACK assembly process. Therefore, the lithium battery protection board manufacturer uses the protection board for the battery pack assembly. Some requirements were also raised. 1. The polarity of the nickel strip pad of the lithium battery protection board cannot be exactly the opposite of the polarity near it. When designing the PACK, try to keep the positive and negative poles of the battery as wide as possible. Otherwise, during the process of welding the nickel strip, or assembling the battery cell and It is easy to cause a short circuit during transportation and use, which will cause the battery to explode. 2. When the lithium battery PACK is designed and assembled, the position of the reed and the pad of the nickel strip should not be exactly opposite, otherwise the soldering iron temperature will be too high during the process of soldering the nickel strip. The welding time is too long and it melts, causing the reed to fall off easily in future use. 3. When designing the size of the nickel strip and reed pads, PACK should be set according to the detailed conditions of the nickel strip and reed. The pads must be large enough to not easily cause false soldering of the nickel strips. 4. If the reed is attached to the lithium battery protection board, pay attention to the length and width of the reed to be as large as possible, so as to prevent the reed from falling off during ultrasonic waves. 5. When assembling and processing the lithium battery PACK, be careful not to connect tin, and at the same time control the soldering temperature and soldering time. At the same time, pay attention to not soldering. When using a special protective board, you must choose a special solder paste.
