Everything PCB !

There are three major types of materials used for fabrication of PCBs:


This is the most commonly used material in PCBs. It is a glass reinforced epoxy laminate sheet. The epoxy used is flame retardant and water resistant. It provides good strength to weight ratios. The tensile strength offered by this material is very high.

PTFE (Teflon)

PTFE is a kind of plastic material that does not provide any resistance, thus is used for high speed, high frequency applications. PTFE is extremely flexible, making it invaluable in applications with tight tolerances. It is also extremely lightweight, allowing it to be used across various industries. It is also flame resistant, exhibits high physical strength, provides temperature stability, and is versatile in application.


The traditional materials of copper, aluminum, iron, etc. are still used in PCBs. These materials allow the use of Surface Mount Technology (SMT) for the integration of components. They also provide mechanical durability. Thus, the product life of metal base PCBs is much longer.

The different materials used for the PCB design and fabrication, all offer a variety of advantages and disadvantages. The material is chosen according to the application, the result needed, environmental factors, and any other constraints the PCB will face. You should choose the material of the PCB depending on the results that are expected.

How to choose the correct material for PCB?

When you choose the PCB materials, you need to take quality into consideration that is quite important in your board, because it can offer superior performance for the full duration of PCB’s expected lifespan. So you can choose the PCB materials based on your demands.

When to choose standard FR-4?

Save product costs and is affordable and effective for many applications.

When to choose Rogers materials?

if you need dielectric PCB properties in your boards, rogers materials is a good choice with higher performance and electrical properties, especially the power management, such as high speed designs, RF, microwave, or mobile applications.

When to choose metal core?

if you are making a electronic project of LED based products, choose the metal core in your boards. What’s more, metal core PCB is more and more common in a variety of lighting applications-for home, workplace, and vehicle.

When to choose HDI material?

HDI technology is a good solution for smaller and lighter products, high-tech applications, denser BGA and QFP packages, as well as lowered heat transfer included stress.

When to choose high Tg?

If there is a higher power density in electronic products and heat generation will tend to disturbing heat sink or other parts of the products, so high Tg PCB is the best solution. What is more, you can find that high Tg PCBs are applied in electronic industries which can operate in relatively high temperatures as high Tg PCB are more and more popular in recent years.
