Isola PCBs are specially prepared for usage in a variety of applications, including high-speed telecommunications and industrial instrumentation.

Types of Materials Used in Isola PCB

Isola PCBs are constructed by using a variety of materials. These materials are listed below:


  • In the PCB industry, the term “prepreg” means a dielectric material that provides electrical insulation and has other valuable properties. Prepreg is prepared by infusing fiberglass fabric with uniquely formulated resins.
  • The resins used in the prepreg give special thermal, electrical, and physical characteristics to the prepreg material leading to enhanced performance of Isola PCBs.

Copper Clad Laminates


  • Copper-clad laminates have a prepreg layer that is sandwiched between the two thin copper foil layers at each end.
  • This lamination procedure entails subjecting one or more layers of copper and prepreg to elevated temperatures and applying pressure and vacuum conditions, to effectively bond them together.

Key Attributes of ISOLA PCBs

  •  Cutting-Edge Material Technology: ISOLA PCBs are prepared using advanced materials that are known for their outstanding electrical characteristics, thermal conduction features, and signal integrity.
  •  High-Speed Performance: The unique characteristics of ISOLA materials lead to the creation of high-speed PCBs that are capable of transmitting signals at very high speeds while minimizing signal loss.
  • Enhancing Signal Consistency: ISOLA PCBs are specially designed to minimize the distortion of signals. They guarantee that the transmitted signals will maintain their signal consistency without compromise.
  • Effective Heat Management: The high thermal conductivity of ISOLA materials plays a great role in heat dissipation, preventing component overheating and ensuring continuous and reliable operation.
  • Dependability: ISOLA PCBs are prepared with a special focus on long-term reliability, making them ideal for applications where failure is not acceptable.

Constructing the Multilayer Isola PCB

  •   Prepreg and CCL play a vital role in the manufacturing of Isola PCBs.
  •   In the first stage, the copper surfaces of the laminate are chemically etched to form electronic circuits.
  •  To form a multilayered structure, etched laminates are combined by introducing one or more prepreg layers between each of them.
  • After this procedure, plating and hole drilling procedures are carried out to establish electrical connections between the various layers of the PCB.
  •  The resulting Isola PCB serves as a highly dense interconnected device where semiconductors and other components can be mounted.

Features of the Isola Prepreg Materials

Here are the key features of Isola PCB materials:

  •       They maintain bond strength at high temperatures.
  •       They offer halogen-free alternatives.
  •       They have superior thermal management and resistance.
  •       They minimize delamination due to machining.
  •       They improve processing by reducing brittleness.
  •       They provide a long-lasting resin system.

What Laminate Materials are Utilized in Isola PCB

Some frequently used laminate materials that are used for creating Isola PCBs are listed below:


The DE104 material has high thermal resistance due to its low coefficient of thermal expansion (CTE) and a unique resin system in the Z-axis. DE104 is further preferred due to its decomposition temperature of 315 degrees Celsius and a glass transition temperature of 135 degrees Celsius. At a temperature of 260 degrees, this material exhibits a delamination time of 12 minutes. It can be prepared by using standard parameters and is typically known as FR-4.

Astra MT77

The Isola PCB laminate material, known as Isola Astra MT77, boasts impressive electrical characteristics. It sustains a consistent dielectric constant within the temperature span of -40 degrees Celsius to +140 degrees Celsius. Additionally, it exhibits remarkably low dissipation, measuring at a mere 0.0017. These attributes position it as a cost-efficient substitute for PTFE and other conventional microwave laminate materials frequently employed in Isola PCBs.


This Isola PCB laminate excels in performance, meeting industry standards for high-performance epoxy PCB materials. It is specifically designed to fulfill the demands of multilayer PCBs.It preserves the conventional FR-4 processing method during its production. FR406 has excellent chemical and thermal performance that ensures the best performance when used in isola PCBs.


It is made up of a tetra-functional epoxy resin that is specially designed for multilayer Isola PCB applications. It is used in those heavy devices that require a high-performance PCB. The FR402 formula was developed to increase the performance and efficiency of laser-based AOI (Automated Optical Inspection) devices. Furthermore, it shows exceptional resistance to both chemical and thermal degradation.


The ED130UV epoxy laminate meets the requirements for UV-blocking materials in PCB fabrication. These Isola PCB laminates use an epoxy resin base along with advanced epoxy resin face plies. These are high-functioning laminates. When used in Automated Optical Inspection, the ED130UV increases the UV fluorescence and blocking abilities.


The Isola material exhibits high-performance capabilities, boasting a temperature resistance of up to 230 degrees Celsius. It is an integral component of the FR-4 system, tailored to excel in multilayer PCB applications that necessitate superior thermal performance and reliability. Isola’s FR408HR laminate materials and prepreg are crafted from a multifunctional resin compound reinforced with E-glass fabric.


The examination of how materials behave under the influence of heat and pressure is known as Rheology. In this process, individuals examine a material’s viscosity in relation to temperature, heat application rate, applied shear, and various other factors. The conventional method used for describing the Rheology of PCB materials involves placing the material of interest between two parallel plates. In this setup, one of the plates moves parallel to the other leading to the deep examination of material behavior.

Material used for the Resin System of Isola PCB?

Isola PCB uses non-flow polyimide-based prepregs that are specially designed for PCB applications. It is used in those devices that involve high-temperature requirements. These are suitable for applications requiring higher performance. Isola PCB’s resin system gives the best performance as compared to the conventional thermoset polyimide resin structure.
