In this article, we’ll explore the unique material characteristics and diverse applications that set these busbar solutions apart. the relevant information is available for PCB design engineers to refer to in the selection of materials, And you can also call QFPCB to discuss. QFPCB offers ‘ready to use & install’ products by mounting the cables or components in-house. This reduces assembly time and simplifies your supply chain.
What is The ROLINX Busbar?
Rogers ROLINX busbars are recognized as the global industry leader in laminated busbar technology. A laminated busbar is a multilayer construction of conductors: copper or aluminum separated by thin dielectric materials, laminated in one structure. Electrically, it is a multilayer electrical circuit that distributes the electrical current from capacitors (buffer) to power modules (IGBT) through specific connections.
Designed for efficient power distribution, these busbars consist of copper or aluminum layers separated by insulating materials and laminated into a compact, integrated structure. Engineers select ROLINX busbars due to their exceptional quality and reliability, as well as the company’s expertise in electrical and mechanical engineering. Additionally, ROLINX offers co-engineering support, flexible lead times, and broad applicability across high power markets, including EV/HEV, rail transportation, and renewable energy sectors.
ROLINX busbars are constructed and manufactured laminated busbars that meet the strictest requirements for railway drive converters, network, wind and solar converters, as well as drives for industrial applications. They have a low inductance, controlled partial discharge, high current capacities and compactness. Embrace the future of power management with Rogers ROLINX®—where innovation meets reliability, ensuring your systems run smoothly and efficiently in today’s ever-evolving technological landscape.
