PCB Manufacturing Battery Management System

In the PCB manufacturing process, the quality problems that occur are basically tinyproblems, because the systems involved are more complicated. Let us give a brief overview below:

Layer:Double-sided

Substrate: FR4 TG170

plate thickness： 1.6MM

Copper thickness： 2OZ

Process: lead-free tin spray, green oil white letters

1. In PCB manufacturing, the solder paste adhesion is not enough to keep the component in the corresponding positionwhen the chain is shaken or the component is stopped during emergencycondition

2.The solder paste has exceeded the service life;

3. The vacuum system of the SMTmachine is unstable;

4,Solder paste precipitation imbalance after PCB manufacturing and SMT processing printing;

5, The specific gravity of the flux is too high, which will cause component displacement during the flux flow process.

The centralized battery management system concentrates all battery system functions in one controller. It is more suitable for the occasion where the battery capacity is relatively small and the module and battery pack type are relatively fixed, which can significantly reduce the system cost. Aiming at the inconsistencies in the manufacturing and use of the battery, and the changes in battery capacity and internal resistance with the battery life cycle, the HiRaintechnology team creatively applied multi-state joint estimation, extended Kalman filter algorithm, and internal resistance / capacity online identification Method to achieve high-precision state estimation of the battery's entire life cycle.

OurPCB manufacturing plants will never use fakematerials and never use recycled materials to ensure that each type of product meets customer and market needs.

Stable suppliers ensure our production needs and meet customers' PCB manufacturing processing production requirements.

Each product has passed the strict inspection and testing of QC, AOI etc.

For Shenzhen FASTPCBA Co., Ltd., the main body of automotive electronics PCB manufacturing, every detail is significant!
