What is the Class-Wire Harness Flexible PCB Manufacturing Technology?
In recent years, the rapid development of high-end industries such as intelligent connected vehicles and low-altitude aircraft has driven continuous innovation in flexible printed circuit boards (FPCBs). In traditional automotive applications, certain wiring and distribution functions rely on wire harnesses, as illustrated in Figure 1. Conventional wire harnesses feature a structure where copper wires are encased in plastic insulation[...]
How Flexible PCBs Power Formula Student Race Cars: Design and Applications
Flexible Printed Circuits (FPC) have emerged as an ideal alternative to traditional wiring harnesses in the electrical systems of Formula Student China race cars due to their lightweight, bendable nature, and high-density wiring capabilities. Within the confined cabin space of FS vehicles, the electrical system faces dual technical challenges: ensuring operational reliability while optimizing spatial layout. This is particularly[...]
Flexible Coating Materials in Circuit Board Manufacturing
Flexible coating materials play an increasingly critical role in the modern circuit board industry as electronic products continue to evolve toward higher density, lighter weight, and greater mechanical reliability. From flexible printed circuits (FPCs) to rigid-flex and high-reliability PCBs, these materials are widely applied to protect conductive traces, enhance environmental resistance, and maintain electrical performance under repeated bending, vibration,[...]
Flex PCB Manufacturing Explained: Materials, Layup Structures, and Production Processes
Printed Circuit Boards (PCBs) are the foundational building blocks of modern electronic systems, providing both electrical interconnection and mechanical support for electronic components. As electronic products continue to evolve toward higher density, thinner profiles, and more complex functional integration, PCB technologies have diversified to include rigid, flexible, and rigid-flex structures. Each PCB type employs carefully selected materials—such as copper[...]
What is the relationship between PCB trace width and current?
In PCB design, current-carrying capacity is one of the most misunderstood yet most critical parameters—particularly in power electronics, motor drivers, and high-current control systems. While signal integrity, impedance control, and EMC often receive significant attention, trace current capacity is frequently reduced to rough rules of thumb or “experience-based judgment.” This approach works—until it doesn’t. Unlike wires, PCB traces are[...]
Optimizing Flexible PCB Design with Heuristic A* Algorithm for FPC Routing
Modern electronic devices are trending toward thinner, lighter, and more highly integrated designs. Consequently, FPC design and the A* algorithm have emerged as key research directions for optimizing flexible circuit board routing. Flexible circuit boards (FPCs), valued for their bendability, compressibility, and high reliability, are widely adopted in consumer electronics and high-end electronic systems. However, their routing design demands[...]
