What is The NPG-170D PCB Material?
NPG-170D is designed with a glass transition temperature (Tg) of 170℃ (DSC), delivering superior thermal stability during both assembly and end use. It is engineered to support lead free assembly and deliver long term reliability in diverse electronic products. Its dielectric constant (DK 4.0 @1GHz) and dissipation factor (DF 0.005 @1GHz) are optimized to support signal integrity, making it suitable for high speed digital circuits applications.
Environmentally, NPG-170D stands out by being halogen, antimony, and red phosphorus free, aligning with global green initiatives such as RoHS and REACH. It also utilizes reactive type flame retardants, ensuring UL 94V-0 flammability compliance without compromising on safety or performance.
Dimensional stability is another strong point. Thanks to its low coefficient of thermal expansion (CTE) and high Tg, NPG-170D offers excellent through hole reliability and reduced warpage critical attributes for multilayer PCB designs. Furthermore, its UV blocking formulation enhances compatibility with AOI processes, while its CAF resistant (anti-migration) resin system ensures long term insulation reliability. The material is also classified as ANSI type FR-4.1, reinforcing its status as a dependable, general purpose laminate. This laminate is perfectly suited for mobile phones, portable electronics, notebooks, PCs, displays, OA equipment, game stations, and communications network equipment.
