Introduction

Rogers DiClad 527 laminates are actually composite materials that are made up of woven fiberglass reinforcement and are based on PTFE. They're specifically designed for use as substrates in printed circuit boards.

That makes DiClad 527 laminates really stand out is the ratio of fiberglass reinforcement to the PTFE content. Rogers has carefully calibrated this ratio to be higher than what you might find in other similar products. This meticulously balanced composition leads to an enhanced dimensional stability and registration.

Features

DiClad 527 material boasts several advanced features that make it an exceptional choice for high-performance applications.

One of its key attributes is the dielectric constant (Dk), which ranges from 2.40 to 2.60, tested under both 10 GHz and 1 MHz with 23˚C at 50% relative humidity.

Additionally, it features a dissipation factor of 0.0017 at 10 GHz and 0.0010 at 1 MHz, which minimizes energy loss during signal transmission, making it ideal for high-frequency applications.

DiClad 527 also excels in electrical protection with a dielectric breakdown voltage exceeding 45 kV and an arc resistance that surpasses 180 seconds.

Its thermal properties features the copper matched coefficients of thermal expansion (CTE) in the x, y directions, which enhance dimensional stability under thermal stress.

DiClad 527 offers significant safety benefits. It meets the V-0 rating under UL 94 standards. Moreover, its low moisture absorption rate of 0.03% enhances reliability in humid conditions.

Finally, DiClad 527 satisfies NASA's strict outgassing criteria. It has a low total mass loss of 0.02% and a Water Vapor Recovered rate of 0.01%. These features make it ideal for use in space and other delicate environments.

PCB Capability

DiClad 527 PCBs offer remarkable versatility.

They are available in single-sided, double-sided, multi-layer, and hybrid configurations, enabling designers to select the optimal layout for specific circuit requirements.

Copper weight is available with options of 1 oz (35µm) and 2 oz (70µm), allowing for customization based on power and current-handling needs.

In terms of outline size, DiClad 527 PCB can handle dimensions up to 400mm x 500mm, making it suitable for a wide array of electronic devices, from compact gadgets to larger-scale equipment.

To meet both aesthetic and functional demands, the PCB comes in a variety of solder mask colors, such as green, black, blue, yellow, red, purple, and others.

Finally, we offer an extensive range of surface finishes to accommodate different project needs. Options include immersion gold, HASL, immersion silver, immersion tin, ENEPIG, OSP, bare copper, and pure gold.

Applications

DiClad 527 PCBs find typical applications in various fields, such as radar feed networks, commercial phased array networks, low - loss base station antennas, guidance systems, and digital radio antennas.
