Functions and features of the PCBA:

-- The rigid flexible circuit board replaces the voltage sampling harness, using the flexible circuit board's higher tolerance temperature (the substrate is generally polyimide, The general withstand temperature can reach 260 degrees Celsius) and the objective structural design of the possibility of short circuit is very small (the printed line is enclosed in the substrate parallel distribution, the possibility of accident fusing is greater than short circuit > Improve the reliability of the power battery module.

-- In the battery module, the scheme that uses the "FLEXIBLE PRINTED CIRCUIT (FPC)+ bonding process" to sample the voltage of each single battery has the advantages of low cost, high space utilization, and automated production compared with the traditional wire harness sampling scheme.
