2.Rigid Laminates-
The rigid sections of the PCB are typically made from materials such as FR4 or ceramic laminates. These materials provide stability and support for larger components while ensuring that the rigid areas remain structurally intact while allowing flexibility in other sections.
3.Thermal Management and EMI Shielding-
High thermal conductivity materials are often chosen to manage heat in main applications. Similarly, materials with EMI shielding properties help reduce interference and ensure the PCB performs well in environments where electronic noise could affect performance.
Designing for High-Speed Signals and Low Noise in 18 Layer Rigid-Flex PCBs
In high-speed and high-frequency applications, keeping signal clarity and minimizing noise is a must. The design of the 18-layer rigid-flex PCB has to address these challenges by ensuring the proper routing, managing impedance effectively, and controlling electromagnetic interference (EMI). Here’s a closer look at how these design factors shape the performance of the overall PCB:
