Why is high frequency PCB turnaround time longer than standard FR-4 boards
High-frequency PCBs require 30% to 50% longer turnaround times than standard FR-4 boards because their specialized PTFE or thermoset materials demand ultra-precise CNC drilling controls, slower chemical processing cycles, and mandatory plasma desmear steps to prevent delamination and maintain strict signal integrity. Why Do PTFE and Ceramic-Filled Substrates Extend Lead Times? The Direct Answer Specialized […]
