FR4 yellow board/FR4 green board

FR4 yellow and FR4 green boards are widely used in the electronics industry for various applications such as circuit boards, connectors, and other electronic devices. Made from a composite material of woven glass fabric and epoxy resin, these boards offer high mechanical strength and excellent electrical insulation properties. The FR4 material is flame-retardant, which ensures durability and safety in electrical applications.

These boards are available in different thicknesses and sizes, suitable for both low and high-frequency applications. The yellow and green colors are primarily due to the specific laminate types used during the manufacturing process, with the color itself not affecting the electrical performance. FR4 boards are commonly utilized in the production of consumer electronics, automotive systems, and industrial equipment, providing a reliable and cost-effective solution for a variety of designs. Their flexibility in manufacturing and high performance make them a popular choice for engineers and manufacturers globally.
