FR4 is the most commonly used PCB substrate thanks to its balance of electrical performance, mechanical strength, and cost. This article explains FR4 properties, high TG materials, major laminate suppliers, and where FR4 remains the preferred choice in modern PCB manufacturing.
High TG FR4 is designed for PCB applications requiring improved thermal stability and reliability. It reduces warpage, improves via performance, and is widely used in automotive, power electronics, and server systems. However, for RF and high-speed designs, low-loss materials are still required.
PCB manufacturing relies on a combination of substrate materials, copper foils, prepregs, solder masks, and surface finishes. Understanding the characteristics of FR4, high-frequency laminates, polyimide, and metal core materials helps engineers select the right solution for performance and reliability requirements.
