What does Isola PCB mean?
This type of printed circuit board is complex and manufactured using high-performance laminates. It contains resin components designed to meet demanding performance requirements.
This type of PCB is used in most electronic devices such as aerospace equipment and high-end consumer electronics.
Types of Materials Used in Isola PCBs
There are materials used to manufacture Isola PCBs. Some of them include:
Prepreg
This term is associated with the PCB industry. This is called “prepreg”. This is a dielectric material that provides electrical insulation, as well as other important functions. It is made of a glass fiber fabric infused with a uniquely formulated resin.
This resin combines different thermal, electrical, and physical properties with the prepreg. This is important for the correct operation of the Isola PCB.
Copper Clad Laminate
This includes a prepreg laminate with a thin layer of copper foil on both ends. This lamination is achieved by compressing one or more layers of copper and prepreg together under extreme heat, pressure, and vacuum conditions.
Building Multilayer Isola PCBs
Prepreg and CCL are used to manufacture multilayer Isola PCBs through complex operations involving multiple processes that are often repeated.
The copper surface of the laminate is etched. This is to produce electronic circuits. Próximo, the laminates are assembled by inserting one or more layers of prepreg between each etched laminate to form a multilayer structure.
Then electroplating and drilling form electrical interconnections between the PCB layers. The resulting Isola PCB is an interconnect gadget where semiconductors and other components are mounted.

What materials are used in the resin system of Isola PCBs?
Isola PCBs use no-flow prepregs, which are based on polyimides and are suitable for PCB applications that require high temperatures.
They use a polyimide flame retardant resin system, which is ideal for applications that require superior performance and thermal properties. Isola’s prepregs use a blend of polyimide and thermoplastic resins that can be fully cured without the use of methylene dianiline (MDA).
This results in a polymer with a high Tg, without the issues of brittleness and low initial bond strength. As a result, the resin system of Isola PCBs is far superior to the resin structure of traditional thermoset polyimides.
Characteristics of Isola Prepregs
Here are some of the key characteristics of Isola PCB materials:
Maintains bond strength at high temperatures
Available in halogen-free options
Higher thermal performance
Reduces delamination due to machining
Improves processability due to reduced brittleness
Long service life of the resin system
