| Abstract Scope |
In electric vehicles, conventional wire harnesses are commonly used to transmit electrical and data signals between the battery system and other essential components. However, wire harnesses come with weight and space limitations. To address these challenges, there is a growing interest in replacing traditional wire harnesses with long-length flexible printed circuit boards. For the manufacturing of long-length flexible printed circuit boards, many changes and challenges need to be overcome. Especially, in the lamination process, there are limitations to achieving longer lengths with conventional sheet and quick press technology. To overcome the challenges of conventional press technology, a continuous roll lamination process has been developed to fabricate long flexible printed circuit boards. By controlling the pressure and temperature of the roll laminating, the gap between the circuit widths was successfully encapsulated with adhesive material, demonstrating that filling was achievable at around 500 μm.
This work was funded by the Technology Innovation Program (20023932, Development of direct laminating system for 3m grade flexible sensing cable for electric vehicle battery module). |
