What is FR-4
The FR-4 is the most common dielectric material used in Printed Circuit Boards. This base material separates copper layers in the PCBs and provides mechanical support to the PCBs. It is a National Electrical Manufacturers Association (NEMA) standard for glass-reinforced epoxy laminate material. The substrate is a composite material in nature, achieved by combining fiberglass and epoxy resin.
FR-4 VIDEOSSemshine Technology Co., Ltd, which has specialized in making PCB since 2006, offers one-stop PCB manufacturing services, ranging from raw material and electronic components procurement, and PCB fabrication, to PCB assembly, testing, and after-market service.
What are the Advantages of FR-4 Materials PCB?
FR-4 printed circuit board material is widely available and low in cost. Still, they provide exceptional quality functioning. However, the price for a high glass transition temperature and high comparative tracking index material is a bit high.
High Dielectric Strength
FR-4 material provides high dielectric strength somewhere between 4.25-4.55 depending on different factors such as glass weave style, thickness, resin content, and copper foil roughness. The dielectric strength defines the maximum electric field that a dielectric material or insulator can resist either without breakdown or becoming electrically conductive. So, choosing a material with higher dielectric strength guarantees the exceptional quality of the insulator.
As we know that FR-4 is a combination of fiberglass and epoxy resin, and it provides high load-bearing capacity and mechanical strength to the overall PCB. But mainly, the strength and load bearing depend on the thickness of the material. The thickness of a standard FR-4 material varies between 0.2 to 3.2m
FR-4 provides moisture resistance. Humidity cannot affect FR-4 printed circuit boards such as contracting and expanding them. However, moisture absorptions affect the electrical and thermal of the material as well as the power of the material to resist conductive anode filament (CAF) formation when the circuit is powered on. Therefore, providing high moisture resistance gives an edge to FR-4 to use as the base PC material and makes it compatible to use under highly humid areas and other marine PCB applications.
Higher Glass Transition Temperature
FR-4 is highly temperature resistant providing a Tg value of 150Tg or 170Tg. The Tg denotes the glass transition temperature of the PCB. Glass transition temperature defines at which point or temperature the PCB will start getting softened and losing its shape. That is why the Tg value of PCB matters a lot. Because a higher number of Tg values ensures better performance of PCB. The Tg value of PCB not only affects temperature resistance but also affects moisture and chemical resistance.
Higher Decomposition Value
The decomposition temperature (Td) defines the temperature where a PCB's almost 5% of the laminate's mass is lost due to decomposition. FR-4 PCB material provides a higher decomposition temperature of >345 Celsius. A high decomposition temperature offers better protection and long life for the printed circuit board.
