Today, we're going to introduce a newly shipped PCB based on DiClad 870 laminates.

Introduction of DiClad 870:

Rogers DiClad 870 laminates are woven fiberglass reinforced, PTFE-based composites that offer lower dielectric constant for use as printed circuit board substrates. By using fewer plies of woven fiberglass and a higher ratio of PTFE content, the DiClad 870 laminates offer lower dielectric constants (Dk) and dissipation factors at a similar thickness to other laminates in the DiClad series. 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:

Dielectric constant (Dk) of 2.33 at 10 GHz and 1 MHz, 50% RH
Dissipation factor of 0.0013 at 10 GHz, 0.0009 at 1MHz, 50% RH
Moisture Absorption 0.02%
CTE in X-axis of 17 ppm/°C, Y-axis of 29ppm/°C and Z-axix of 217ppm/°C
Copper Peel Strength of 14 lbs/in
UL 94-V0 Flammability
NASA outgassing: Total mass loss of 0.01%, Collected Volatiles of 0.01%, Water vapor recovered of 0.01%
