Widely Used FR4 Material PCB From Sunsoar CircuitFR-4 glass epoxy is a popular and versatile high-pressure thermoset plastic laminate grade with good strength to weight ratios. With near zero water absorption, FR-4 is most commonly used as an electrical insulator possessing considerable mechanical strength. The material is known to retain its high mechanical values and electrical insulating qualities in both dry and humid conditions. These attributes, along with good fabrication characteristics, lend utility to this grade for a wide variety of electrical and mechanical applications.Model TypeCustomized PCBLayer1-20 layerKey WordsFR4 PCBBase MaterialFR4, High-TG FR4Board Thickness0.2-3.2mmCopper Thickness0.5-5.0 OZMin.
