6 Layer High Frequency PCB Built on 3 Cores of 20mil RO4003C and 4mil RO4450F for Radar Altimeter

(Printed circuit boards are custom-made products; the images and specifications shown are for reference only.)


Introduction

Hello Everyone,
Warm greetings!
Today, we are discussing a type of 6-layer high-frequency PCB. This PCB is constructed using three cores of 20mil RO4003C, bonded with RO4450F prepreg, specifically designed for radar altimeter applications. Below is the stack-up configuration.



The RO4003C family includes six core thickness options, ranging from 8mil (0.203mm) to 60mil (1.524mm):
