  1. Your electronic project with various PCB material

With the development of electronic technology, the circuit board plays such an important role in electronic products, medical devices, industrial equipment, safety and security equipment and so on. So what kinds of PCB materials you choose will make a great effect on the functionality, manufacturability and life cycle of your board.


In fact, FR-4 refers to a grade of material rather than a material, which is a composite material for glass-reinforced epoxy laminate material. FR-4 is made up of woven fiberglass cloth with an epoxy resin binder that is flame resistant. And FR stands for flame retardant, it denotes that the material complies with the standard UL94V-0.

Note: FR-4 material provides the fundamental standard for PCB substrates, keeping a widely effective balance between cost, durability, performance, manufacturability, as well as electrical properties.

Standard FR-4: save product costs and is affordable and effective for many applications.

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.

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.

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.
