4.Do you know what is FR4?
FR-4 is a grade designation for flame-retardant fiberglass reinforced epoxy material. Thus, FR-4 PCB offers a much greater level of resistance to heat than a standard PCB. FR-4 circuit boards are divided into four classifications that are determined by the number of copper trace layers found in the material:
• Single-sided PCB / Single-layer PCB
• Double-sided PCB / Double-layer PCB
• Four or more than 10 layers PCB / Multilayer PCB
Providing the Right High-Temperature PCB for Your Applications
Uniwell offers a wide selection of high-temperature PCB products manufacturing services either with FR-4 or other high-quality heat- and temperature-resistant Tg materials. We are able to perform high-temperature PCB fabrication for automotive, industry and high-temperature electronics applications. We can manufacture High-Tg PCBs with a Tg value of up to 180°C. Following table lists some of our commonly used materials for High-Tg PCBs production.
