What Is Isola’s PCB ?

This is a Complex printed circuit boards are fabricated with high-performance Isola laminates materials.

The product incorporates proprietary resin constituents engineered to meet the most demanding performance requirements.

This PCB is utilized in the most important electronic devices, including top-of-the-line consumer electronics as well as aerospace equipment.

Types Of Materials Used in Isola PCB

The components utilized in the production of Isola PCBs include:


impregnated material or prepreg is a dielectric material that is characterized by unique characteristics and electronic insulation. When manufacturing prepreg, a technique called fiberglass fabric infusion is employed, which is usually used to rectify Isola PCB’s method.

Copper Clad Laminates

This copper-clad laminate or CCL is created by suppressing a few of copper and prepreg layers combining them in conjunction with one another. For the Isola PCB maker, this procedure is best done under high pressure, temperature, and vacuum circumstance.

What Is the Material Used To Make Isola’s PCB Resin System ?

Isola PCB makes use of no-flow prepregs. They are polyimide-based and are suitable for PCB applications that require high temperatures.

They utilize a polyimide-based retardant resin system that is ideal for applications that require higher performance and better thermal properties. The materials that make up the prepreg of Isola use a blend of polyimide and thermoplastic resin. They can be fully cured without making recourse to Methylenedianiline (MDA).

This leads to in polymers with a higher Tg that avoids the issues of brittleness as well as weak bond strength at the beginning. The resin structure that is the basis of Isola PCB is superior to the structure of the resin of thermoset polyimide, a traditional thermoset.

Constructing the Multilayer Isola PCB

Manufacture of multilayered Isola PCBs utilizes prepreg and CCL through complex operations involving multiple processes.

The laminate’s copper surface is cut. This creates electronic circuits. Going forwards, by inserting one or more prepreg plies between each etched laminate, the laminates will be assembled to form a multilayer structure

Plating and hole drilling follows the creation of electrical interconnections among PCB layers. In the end, the Isola PCB that results will serve as a device for interconnecting semiconductors and other components.

The Advantages of Isola PCB Laminate

Isola substrates are high-performance, 180°C glass change temperature (Tg). FR-4 system is suitable for multilayered Printed Wiring Boards (PWBs) where maximum thermal performance and reliability is required.

Isola laminates and prepregs are produced using a special multifunctional epoxy resin that is high-performance and which is reinforced by electric grade (E-glass) glass fabrics.

While maintaining FR-4’s processability, this system offers improved thermal performance and lower expansion rate compared to conventional FR-4 systems.

Alongside this outstanding thermo-performance, it also has superior mechanical water and chemical resistance characteristics that match or surpass the capabilities of conventional FR-4 materials.

What Laminate Materials Are Utilized in Isola PCB ?

Now, let’s take a look at the most common laminate materials that could be utilized in the manufacturing of Isola PCBs:

Astra MT77

The laminate material used in Isola PCB comes with great electrical features that remain constant across a broad spectrum of temperatures and frequencies.

It has a stable dielectric constant that is within the range between -40 ° Celsius to +140 degree Celsius. Furthermore, Isola Astra MT77 offers a dissipation rate of 0.0017 which is extremely low. This is the reason it’s cheaper than PTFE as well as other microwave laminates that are used commercially for PCB.

The laminate is perfect for a variety of current PCBs for RF/microwave designs.

Isola FR4 MT77 PCB


The DE104 has a high thermal resistance because of its low CTE and unique resin system on the Z-axis. DE104 is also equipped with the decomposition feature and glass temperatures between 315 degrees and 135 degrees Celsius and 135 degrees Celsius, respectively.

The time it takes for the laminate to be delaminated at an temperature of 260 ° can be as long as 12 minutes. The material can be processed with standard parameters and is generally referred to as FR-4.


This laminate made of epoxy made by ED130UV allows you to meet the specifications to make PCBs using a material that blocks UV. The Isola PCB laminates are created out of the epoxy base with high-tech surface plies of epoxy.

The ED130UV is able to help a lot in UV fluorescence, as well as blocking when used with the Automated Optic Inspection.


It’s composed of tetrafunctional epoxy resin intended for use in applications that require multilayer Isola PCB, which requires high-performance properties that are superior to difunctional epoxy.

The FR402 formulation was to improve the accuracy in addition to throughput AOI devices that use lasers. In addition to this, it offers very good resistant to chemical and thermal degradation


The Isola PCB laminate is the industry standard for high-performance materials for epoxy PCBs. It is designed to meet the specifications of multilayer PCBs and ensure that the traditional FR-4 process is maintained.
