Unique features of the Rogers TMM 10i Laminate

If you are looking for a Laminate with the following characteristics, you have come to the right place. The Rogers TMM 10i laminate is available with the following specifications: Dk = 10, Dissipation Factor = 0.002, Thermal coefficient of resistance (Td) = 425 degC, and thickness in inches. This laminate is also resistant to creep flow, low-cost, and high-performance.

Low dissipation factor

The Dissipation Factor (Dk) of Rogers TMM 10i Laminate is 0.002, and its thermal conductivity is more than double that of traditional PTFE laminates. This material comprises a layer of TMM bonded to brass or aluminum and covered with electrodeposited copper foil. It is available in three standard thicknesses – TMM 3, TMM 4, and TMM 10i.

The high dielectric constants of Rogers TMM laminates provide excellent mechanical and electrical performance. Rogers DiClad laminates are also available with low dielectric constants but don’t incorporate cross-plied constructions. These laminates also offer low dissipation and are often used in high-frequency applications and radomes.

A low dissipation factor of Rogers TMM 10i laminates is essential for microwave circuits. It prevents heat buildup and helps maintain good wire bonding. In addition, this material is highly resistant to high temperature and high humidity, and resistant to creep flow. These properties make it an excellent choice for many RF and microwave applications. In addition, they offer Rayming PCB & Assembly the electrical and mechanical properties to design their devices.

Unfortunately, some PCB designs don’t factor in production costs. This can significantly increase the cost of Rogers PCB substrates. For example, they are switching from a double-layer design to a four-layer one, which doubles the cost of Rogers TMM 10i laminate.

Another essential characteristic of Rogers TMM 10i laminate is its high Dk value. It can handle the highest frequencies and is best suited for high-frequency applications. Compared to FR-4, it has a wide range of Dk values. The Rogers material is also temperature stable. It also offers the lowest loss in high-frequency applications. Aside from a low Dk value, it is an excellent option for high-frequency circuits.

Isotropic dielectric constant

The isotropic dielectric constant of Roger TMM 10i laminate is low, allowing for high thermal conductivity. This material is bonded to brass or aluminum plates and covered with an electrodeposited copper foil. It is available in TMM 3, TMM 4 and TMM 10i laminates. Among its properties, this laminate has a low thermal coefficient of expansion. Its low thermal expansion coefficient and low etching shrinkage make it a good choice for microwave applications.

The Isotropic dielectric constant (Dk) of Rogers TMM 10i laminate is 10. It has a high Dissipation Factor of 0.002 and a thermal coefficient of 19. This means that it supports plated through holes. These dielectric properties are ideal for a variety of electronic applications. However, it is essential to note that the Dk value may vary slightly from one product to another.

Rogers TMM thermoset microwave laminate is a versatile material with a low thermal change rate. It is an excellent choice for high-reliability microstrip and stripline applications. It has many advantages over alumina filler materials in terms of processing, such as accommodating larger copper clad specifications and maintaining tight tolerances. These properties make it an excellent choice for microstrip, stripline, and chip tester applications.

A new generation of microwave circuits is made possible with TMM10, a composite of ceramic and PTFE materials. Its dielectric constant is low – typically 30 ppm/degC – which closely matches copper’s thermal expansion. It also has low etch shrinkage values, making it ideal for applications requiring high reliability. The TMM10i laminate is also twice as thermally efficient as traditional PTFE/ceramic laminates.

Resistant to creep flow

A typical PCB substrate is composed of an FR-4 material, a glass fiber/epoxy composite with copper foil laminated on one side. The FR-4 material offers a good balance between cost and manufacturability and good electrical and thermal properties. Rogers also offers cores and laminates with better high-frequency properties, which are more expensive than fiberglass. However, these laminates offer a lower thermal coefficient.

TMM thermosetting microwave laminates offer the advantages of ceramics and PTFE with a low thermal change rate. They are excellent for high-power applications and have low thermal expansion coefficients. Their low etch shrinkage values and high dielectric constants make them excellent choices for power amplifiers, filters, and couplers. They are also suitable for high-reliability microstrip and stripline applications.


Among the benefits of Rogers PCB laminates is their superiority over standard FR-4 material. However, if you consider purchasing Rogers laminates for your printed circuit boards, you should ensure that you are working with a top-notch manufacturer. RayMing PCB and Assembly Company can provide excellent printed circuit board assembly and manufacturing services. These experts will assist you throughout the design and fabrication process.

The process of putting copper layers on the Rogers TMM 10i laminate involves the application of a pattern plating. Then, a circuit pattern is electroplated. This process requires less copper for the anode bank and reduces the amount of copper removed during the etching process. This helps reduce the overall cost of the substrate. To make the most out of Rogers TMM 10i laminate, you need to understand the difference between a single-axis edge-plated and a multiple-axis margin plated.

While both materials have similar characteristics, the differences between the two materials are apparent in their Dk values. The TMM 10i laminate is more conductive than the TMM 10, with a Dk of -0.01 on the z-axis at 10 GHz. It also has an extremely low thermal coefficient of 19.0 ppm/degC. As a result, it costs less than Rogers TMM 10i laminate.

Another factor affecting the cost of Rogers TMM 10i laminate is the number of layers in the multilayer design. Moving from four layers to six layers would cost fifty percent more. Switching from two to four layers would be equivalent to a hundred percent increase. The surface finish also plays a role in determining the overall cost of Rogers TMM 10i laminate. Specific surface finishes have higher grades, while others provide a long shelf-life but increase the cost of the Rogers laminate in general.


Rogers TMM 10i laminate’s special formula includes several synthetic materials and the common PTFE. Its high dielectric constant provides electromagnetic interference (EMI) reflection suppression, while its low thermal change rate makes it a good choice for high-reliability applications. It offers many advantages compared to alumina filler materials in processing and can accommodate larger copper-clad specifications and maintain tight tolerances. In addition, they come with low thermal coefficients, which provide high reliability in HV transmission. As a result, the TMM 10i laminate is an excellent choice for microstrip, stripline, and chip tester applications.

The cost of Rogers TMM 10i laminate depends on the frequency it is being used at. A high-frequency PCB needs a laminate with a high CTE, and a higher Dk will produce smaller printed circuit boards. In addition, High-frequency PCBs usually require the use of FR-4 material. Rogers TMM 10i laminate is best for such high-frequency applications. If you are considering a Rogers TMM 10i laminate, you may want to consider the advantages it can provide you.
