What circuit boards do we do? (29) DiClad 870 High Frequency PCB

Introduction

Rogers DiClad 870 laminates are woven fiberglass reinforced, PTFE-based composites that offer lower dielectric constant and dissipation factors by using fewer plies of woven fiberglass and a higher ratio of PTFE content.

The woven fiberglass reinforcement in DiClad 870 provides greater dimensional stability than nonwoven fiberglass reinforced PTFE based laminates of similar dielectric constants. The coated fiberglass plies in DiClad 870 materials are aligned in the same direction.

Features

Here are some standout features of DiClad 870 materials.

They exhibit a dielectric constant of 2.33 at both 1MHz and 10 GHz, ensuring reliable signal transmission.

At 10 GHz, these laminates showcase a low dissipation factor of 0.0013, maintaining signal integrity.

DiClad 870 boasts a strong copper peel strength of 14 Lbs/in using 35 μm foil per IPC TM-650 2.4.8 test method, ensuring robust copper adhesion.

The moisture absorption rate is a exceptionally low at 0.02%, guaranteeing stability in various environmental conditions.

Lastly, DiClad 870 meets UL 94-V0 flammability standards, ensuring high safety and fire resistance.
