FR4 is the most widely used PCB substrate material, but in applications with higher operating temperatures, designers often choose high-Tg FR4 laminates. High-Tg materials provide better thermal stability and improved reliability during soldering and long-term operation. This article explains the differences between standard FR4 and high-Tg FR4, including material properties, thermal performance, and typical use cases.
PCB stackup design defines the arrangement of copper layers and dielectric materials inside a circuit board. In FR4-based PCBs, the stackup structure determines signal integrity, impedance control, and overall mechanical stability. This article explains how FR4 PCB stackups are designed and what engineers should consider when planning multilayer boards.
FR4 PCB thickness is an important parameter in printed circuit board design because it affects mechanical stability, manufacturing compatibility, and product integration. While many thickness options are available, several standard values such as 0.8 mm, 1.0 mm, and 1.6 mm are widely used across the electronics industry. This article explains these common FR4 PCB thickness standards and how they influence design decisions.
FR4 is the most widely used PCB substrate material in the electronics industry. It offers a balance of mechanical strength, electrical insulation, and cost efficiency, making it suitable for a wide range of electronic applications. This article explains the key properties of FR4 materials, their advantages and limitations, and where they are typically used in PCB design.
