Comparison of PCB Materials for High Speed and HDI PCB Boards
Takeaways: The right coating or finish can significantly affect the overall performance of a PCB. For example, a film-based finish for a low-cost PCB won’t perform as well as an epoxy-based finish on a high-end design. An excellent article from the EE Times discusses this topic in more detail at http://www.eetimes.com/document.asp?doc_id=1343506&page_num=8 Section: Electrical Design Takeaway:…
