NPGN-150PYTL, NPGN-150PYR, and NPGN-150PYB are high-performance, halogen-free copper-clad laminates developed by Nan Ya Plastics Corporation. These advanced laminates are engineered for applications demanding superior thermal stability, mechanical strength, and excellent electrical performance, making them ideal for high-frequency, high-reliability, and environmentally-conscious PCB designs.
Key Features
1. Halogen-Free Composition
-
Manufactured without halogens, ensuring environmental compliance with RoHS and green electronics standards.
-
Reduces the risk of harmful gas emission during soldering or high-temperature processing.
2. Flame Retardancy
-
Achieves UL 94 V-0 rating, providing enhanced safety in electronic assemblies.
-
Flame resistance is obtained via phosphorus, nitrogen, and/or inorganic compounds, offering robust protection in demanding applications.
3. High Glass Transition Temperature (Tg)
-
Tg of approximately 150°C allows reliable operation under high-temperature soldering and thermal cycling, suitable for both lead-free and traditional PCB processes.
4. Excellent Electrical Properties
-
Low dielectric constant (Dk = 4.0–4.3) and low loss tangent (Df = 0.014 at 1 GHz) ensure signal integrity in high-speed and RF circuits.
-
Ideal for applications such as telecommunications, industrial control, and automotive electronics.
5. Dimensional and Thermal Stability
-
Low coefficient of thermal expansion (CTE) ensures minimal deformation during processing and thermal cycling.
-
Maintains dimensional accuracy in X/Y-axis (0.01–0.03%) and provides predictable expansion in the Z-axis for reliable plated through-hole (PTH) performance.
