What is Rogers DiClad 527 PCB ?

The Rogers DiClad Series are a family of PTFE-based and fiberglass-reinforced composites used as substrates for printed circuit boards in applications that require high frequency. The DiClad 527 laminate series features controlled ratios of PTFE and fiberglass content, resulting in low dielectric constant ranges. Higher PTFE composition yields improved dimensional stability, lower loss tangent, and better registration. The DiClad 527 series is available in a wide range of thicknesses and PTFE content, and a cross-plied construction is not available for the Rogers DiClad 527.

Features of Rogers DiClad 527

This article covers the features of Rogers DiClad 527, including its high fiberglass reinforcement content, Lead-free process compatibility, and High Coefficient of Thermal Expansion. You may also be interested in reading about the Stability of Dielectric Constant across Frequency. However, it is worth remembering that these are just some of the many benefits this cable offers. This article also looks at its cost, making it an affordable option for Rayming PCB & Assembly.

Stability of Dielectric Constant across Frequency

The high-frequency laminates from Rogers consist of PTFE, a relatively soft dielectric material with a low bulk modulus. As a result, they are lead-free, conform to IEC 61249-2-21, and are highly process-compatible. As a result, Rogers DiClad 527 is an excellent choice for high-frequency applications because it offers both low bulk modulus and stability of the dielectric constant across frequencies.

High ratio of fiberglass reinforcement to PTFE content

One of the advantages of Rogers DiClad 527 laminates is the high ratio of fiberglass reinforcement to PTFE content. This carefully controlled ratio results in better dielectric constant range, improved dimensional stability, and better registration. This combination of properties makes DiClad 527 an excellent choice for low-noise amplifiers, filters, and couplers.

Lead-free process compatibility

If you’re in the market for a lead-free high-frequency laminate, Rogers DiClad 527 may be the material you’re looking for. This high-frequency laminate consists of PTFE, a relatively soft dielectric with low bulk modulus. As a result, it offers a higher dielectric constant and better dimensional stability. Moreover, DiClad 527 has a low-resistance insulating capability, which helps you reduce costs and improve manufacturing efficiency.

Coefficient of Thermal Expansion

A common question relates to the thermal properties of the Rogers DiClad 527 laminate, such as its Coefficient of Thermal Expansion (CTE). As the name suggests, this type of laminate consists of a polymer core made of a glass-ceramic filled PTFE material with a low dissipation factor. These laminates are helpful in thin multilayer PCBs and have the highest embedded resistor constancy in the PCB semiconductor industry.

The PTFE and fiberglass-reinforced PTFE composites in Rogers DiClad Series laminates have controlled PTFE and fiberglass content levels. The increased PTFE content leads to a lower loss tangent. This material also features improved dimensional stability. It is available in various thicknesses from 40 mils to 260 mils and with or without copper cladding.

The Advantages and Disadvantages of Rogers DiClad 527

A thermoset material, Rogers DiClad 527 is ideal for high-frequency PCBs since the 1980s. Its PTFE and fiberglass reinforcement ratios we precisely control, resulting in a broad range of dielectric constants. This provides superior dimensional stability and registration. In addition, the material is very resistant to oxidation, a critical factor in ensuring the reliability and stability of your circuit.

Rogers DiClad 527 is a thermoset material

Rogers DiClad 527 is one of the most popular thermoset materials in the electronics industry. This material has a high dielectric constant and is a common thermoset used to fabricate circuit boards and other electronic parts. It is available in various shapes, sizes, and strengths, making it a good choice for various applications. However, these products may not be suitable for all applications.

Thermoset materials can have different materials, including hydrocarbon ceramic. Hydrocarbon ceramic is a good choice for applications involving microwaves or millimeter-wave frequencies. Rogers RO4000 laminates feature streamlined properties that allow for easier PCB fabrication. Similarly, RO4000 thermoset materials feature a combination of copper matched CTE and ceramic/random glass and are ideal for use in high-reliability applications. Rogers RO4000 and RT/duroid laminates have excellent thermal, mechanical, and electrical performance characteristics.

It is a high-frequency PCB material

There are many benefits to using high-frequency PCB materials like Rogers DiClad 527, a high-frequency variant of FR-4. The main advantage is that the material is inexpensive, and the process is easier than with FR-4. However, the disadvantages of Rogers DiClad 527 outweigh its benefits. Here are three things you should know about this high-frequency PCB material.

Embedded capacitance material: This is a conductive layer used to increase the frequency of a circuit. It helps to improve the sensitivity of an electrical circuit. We use it in a variety of high-frequency applications. For example, a radio receiver uses this material to improve its sensitivity. The other important factor is the price. DiClad 527 is inexpensive but may not be the right choice for all applications.

It has a thick metal cladding

The thickness of a Rogers cladding system varies depending on the cladding material. Thicker claddings are more expensive than thinner ones, but this is usually not an issue in most applications. The difference is the thickness of the dielectric layer. For example, the DiClad 527 has a metal cladding that is half the thickness of the copper itself. This means that the laminates are not as susceptible to damage from impact and will last longer.

The thick metal cloading from Rogers is a good choice for applications where electrical and thermal performance is paramount. Unlike claddings with less metal content, this material is easy to cut and form. We bond the cladding to the substrate with a PTFE-based bonding film. Several other claddings are available, including CuClad 6700, Arlon CuClad 217LX, and the CLTE series.

Applications of Rogers DiClad 527

The Rogers Corporation, founded in 1832, is a leading global supplier of high-performance RF materials. Their extensive product portfolio includes various products that are ideal for a wide range of applications. The search tool offers multiple filters, including location, certification, keyword, etc. To help you narrow down your options, Rogers Corporation offers several search tools.

Edge encapsulation

In PCB fabrication, edge encapsulation can increase the radiation shielding of a PCB design. Edge plating is usually necessary for multiple axis PCB margins, as well as for single-axis margins. The rout path must be properly designed and optimized for the material used in the PCB. Also, we can use it for non-standard Rogers laminates without any glass reinforcement.

Controlled impedance

The controlled impedance of Rogers DiClaD 527 is a good choice for various electronic applications. Its superior impedance properties are critical for achieving a desired level of performance. This material is available in various color and size options. For further details, read the full description below. CuClad 250 is the same material as the Rogers DiClad 527 but with different properties.

Dimensions

If you’re considering purchasing a new router for your next project, consider these dimensions of the Rogers DiClad 527. Its cutting bed holds the material while a routing tool shapes the part. These three dimensions help you determine which router to buy. The average size of this router is 10 mm x 10 mm. The biggest slab on this model is 15 mm in size.
