Arlon Diclad 527 PCB

Arlon Diclad 527 raw material in stock · 8-day prototype lead time

Overview

Arlon Diclad 527 (and its 522 sibling) are woven fiberglass/PTFE composite laminates engineered for low-loss printed circuit board substrates. The glass-fiber reinforcement delivers highly uniform electrical properties across frequency, making it a proven choice for phased-array, radar feed networks and base-station antennas.

Arlon’s High Frequency Materials division is now part of Rogers Corporation. As a manufacturer, Andwin fabricates Diclad 527 PCBs with material in stock and a typical 8-day prototype lead time.

Frequently Asked Questions

1.What is the dielectric constant of Diclad 527?

Diclad 527 has a typical εr of 2.5 at 10 GHz, with a tight range of 2.4–2.65. The woven glass/PTFE construction keeps the value highly uniform across the panel and over frequency.

2.Can Diclad 527 be processed like FR-4?

No. Diclad 527 is a PTFE-based laminate and requires a dedicated PTFE process line (special drilling, desmear and bonding). It must not be mixed with standard FR-4 production.

3. What thicknesses and copper can I order?

Standard cores from 0.13 to 3.05 mm (0.005″–0.120″) with ED or reverse-treated copper 1/2, 1 and 2 oz. Other thicknesses available on request.

4.What is the typical lead time?

With raw material in stock at Andwin, prototype Diclad 527 PCBs typically ship in about 8 days, depending on layer count and via structure.

5.Is Diclad 527 suitable for military radar?

Yes. Its low loss, frequency-uniform electrical properties and chemical resistance make it a proven choice for phased-array networks, radar feed networks and missile guidance systems.
