What is The NP-175FM PCB Material?

At the core of NP-175FM is its high Tg of ≥170°C, making it fully lead free compatible and suitable for advanced soldering profiles. This high thermal threshold ensures the material performs reliably under reflow and operating conditions typical in today’s high density and high power applications.

The material is formulated Dicy free, which improves thermal stability and moisture resistance while eliminating common issues associated with traditional curing agents. Additionally, NP-175FM features a low coefficient of thermal expansion (C.T.E), especially in the Z-axis, helping to reduce the risk of delamination and via failure during thermal cycling.

Electrically, the NP-175FM offers a well balanced dielectric constant (DK 4.2 @1GHz) and low dissipation factor (DF 0.012 @1GHz), ensuring minimal heat generation during signal transmission, which are essential for maintaining signal integrity and low power loss in both digital and analog circuits. Its superior anti-CAF resistance enhances long term reliability in humid and high voltage environments.

For manufacturing, NP-175FM utilizes a multi-functional epoxy system with high luminance, creating strong contrast with copper for AOI processes. This results in better defect detection and improved inspection efficiency. It also meets the IPC-4101C/99 specification, ensuring quality and performance consistency.

Features of The NP-175FM PCB Material

High Glass Transition Temperature (Tg 170°C)

The laminate provides a minimum Tg of 170°C, ensuring superior dimensional and mechanical stability under high thermal loads, making it ideal for use in lead free soldering and high temperature reflow processes.

Dielectric Constant (Dk)

With a dielectric constant (DK 4.2 @1GHz), the dielectric constant of the material is a measure of its ability to store electrical energy in a capacitor like manner. The laminate offer a stable Dk, this property measures a material’s ability to store some electrical energy in a given electric field.

Dissipation Factor (Df)

With a dissipation factor (DF 0.012 @1GHz) translates to reduced dielectric loss, ensuring minimal heat generation during signal transmission, which are essential for maintaining signal integrity and low power loss in both digital and analog circuits.

Lead-Free Compatibility

The laminate is fully compatible with lead free assembly processes, supporting modern RoHS compliant manufacturing standards and ensuring environmental sustainability.

Dicy-Free & Low C.T.E

Designed with a dicy free resin system, the laminate enhances long term reliability and thermal endurance, while reducing the risk of degradation under prolonged high temperature exposure. Additionally, it features a low Z-axis CTE, minimizing the risk of plated through hole (PTH) failures during thermal expansion.

Excellent Anti-CAF Performance

The PCB material also has excellent anti-CAF performance. The laminate’s chemistry and controlled glass treatment provide excellent resistance to CAF, reducing the risk of dendritic growths that can cause shorts in high humidity or high bias conditions.

High Luminance for AOI Inspection

The laminate features a high luminance multi-functional epoxy resin that provides clear contrast with copper surfaces, enhancing automated optical inspection (AOI) accuracy and improving manufacturing yield and quality control.

IPC-4101C/99 Certified

Meeting the IPC-4101C/99 specification, the laminate ensures industry standard compliance, giving manufacturers confidence in its performance, consistency, and reliability.

What are The Applications of NP-175FM PCB Material?

NP-175FM is suitable for a broad range of industries that demand high reliability and performance:

Server
