Meaning of FR-4: Composite PCB Manufacturing Material and Rating Unit.
In electronic engineering, different substrate materials are chosen based on their application characteristics. For instance, high-frequency circuits use Rogers, while RF circuits use Teflon (a comparison of FR4 with other PCB materials is provided below). Typically, we refer to circuit boards based on the substrate material name. FR-4 in PCB has a dual meaning:
For cost-effective projects, using FR-4 to construct circuit boards is a wise choice. It complies with the UL94V-0 standard, providing sufficient mechanical strength and self-extinguishing capabilities. Here, we not only elaborate on FS Technology’s manufacturing capabilities but also provide FR-4 material specifications. Whether you are in the process of selecting substrate materials for your project or seeking FR-4 PCB solutions, you will find this information helpful!
Unlike traditional Chinese companies that separate trade from manufacturing, FS Technology is an integrated PCBA manufacturer with various departments, including Engineering, Procurement, Sales, Production, and Assembly. This integration helps us meet the comprehensive needs of customers both domestically and internationally. With traditional substrate materials like FR-4, we have a strong experience base and set ourselves apart from other manufacturers through breakthrough technologies.
As a manufacturer that focuses on long-term cooperation, “Quality”, “Service” and “Price” as three pillars, that is, providing better services at lower costs so that customers can obtain high-quality products. Based on our service philosophy, we have received a high volume of orders and consistent praise. Our main advantages include:
