Technical Challenges and Solutions
Manufacturing up to 48-layer PCBs requires advanced control of
lamination pressure, dielectric thickness, and signal impedance.
Ring PCB’s experienced engineering team ensures:
Perfect layer registration and consistent lamination quality.
Controlled impedance for high-speed and RF applications.
Excellent thermal management for power and industrial systems.
High reliability in harsh operating environments.
Comprehensive testing to guarantee performance and long-term
stability.
