表面处理对射频PCB电路性能的影响
Impact of Final Plated Finish on RF PCB Performance

大多数印刷电路板在最终加工成形前都会对电路表面导体进行表面处理,以防止氧化和长期使用带来的可靠性问题。通常,表面处理都会影响电路的导体损耗,进而导致电路总的插入损耗变化。本视频就介绍了表面处理对电路的射频性能产生影响及其原因。

Most printed circuit boards are shipped from the fabricator with a final plated finish over the copper conductor in order to prevent oxidation and long-term reliability issues. The final plated finish typically affects the conductor losses and ultimately the insertion loss of the circuit. Watch to learn why final plated finish impacts RF PCB performance.
