2-layer CLTE-MW Pure Gold PCB Green Solder Mask White Legend

This custom 2-layer CLTE-MW™ rigid PCB is an ultra-thin high-frequency RF circuit board built on ceramic filled, woven glass reinforced PTFE composite substrate. With pure gold surface finish and tight dimensional tolerance, the board is constructed to a finished thickness of only 0.2mm. It uses a 0.102 mm CLTE-MW core with 35 μm copper on both layers and contains no blind vias. Manufactured to IPC-Class-2 quality standards, it undergoes 100% electrical testing before shipment. Gerber RS-274-X files are accepted for production, and worldwide delivery is available.

PCB Statistics

CLTE-MW™ Laminate Introduction

CLTE-MW™ laminates are ceramic filled, woven glass reinforced PTFE composites, developed as a cost-effective high-performance substrate for RF designers. Suited for projects with mechanical or electrical thickness constraints, this material series offers seven standard core thicknesses from 3 mils to 10 mils, supporting optimal signal-to-ground spacing for 5G and millimeter-wave circuits. Multiple copper foil options are available, including rolled, reverse treated ED and standard ED; resistive foil and metal plate can be supplied upon request.

Spread glass reinforcement plus high filler loading reduces glass weave effects on electromagnetic wave propagation while maintaining excellent dimensional stability.
