Megtron 6 (M6) R-5775G PCB High Speed Low Loss Multilayer Printed Circuit Board
(Printed Circuit Boards are custom-made products, the picture and parameters shown are just for reference)
Dear PCB friends,
Today, I am going to talk about a type of high speed low loss multilayer PCB: M6 R-5775 PCB.
Megtron 6 is an ultra-low loss, highly heat resistant circuit board material designed for mobile, networking, and wireless applications etc. The main properties of Megtron 6 are low dielectric constant (DK) and dielectric dissipation factors (DF), low transmission loss and high heat resistance.
Part Numbers
Low Dielectric Constant (Dk) Glass Cloth - Laminate R-5775(N) / PrepregR-5670(N)
Standard E Glass Cloth - Laminate R-5775 / PrepregR-5670
Main Features
Low Dk = 3.7 (@ 1GHz), Low Df = 0.002 (@ 1GHz)
Excellent through-hole reliability (5x better than our conventional high Tg FR4 material)
Lead-free, ROHS-compliant soldering
High heat resistance
M6 also provides excellent high-density interconnect (HDI) and thermal performance.
