1. Why Choose Isola High-Performance FR-4 Materials for Your PCBs?

Isola Group is a globally recognized leader in copper-clad laminates and prepregs for the printed circuit board industry. Among its most popular product lines are the 370HR and 408HR series — high-Tg, high-reliability FR-4 materials widely used in multilayer PCBs, high-speed digital circuits, RF/microwave applications, and lead-free assembly environments.

Whether you are designing high-layer-count backplanes, server boards, telecommunications equipment, or automotive electronics, choosing the right laminate is the foundation of product reliability. Minkinzi PCB factory maintains a large in-stock inventory of Isola 370HR, 408HR, and related materials — and our engineering team has years of proven manufacturing experience to turn your design into a high-yield, high-quality board.

2. Isola 370HR – The Industry Benchmark for High-Tg FR-4

Isola 370HR is a high-performance epoxy laminate and prepreg system with a glass transition temperature (Tg) of 180°C (DMA) and a high decomposition temperature (Td) of 340°C. It is the "go-to" material for high-speed, high-layer-count designs.

Key Features:

• High Tg (180°C) for excellent thermal reliability

• Low Z-axis CTE (50 ppm/°C pre-Tg) for superior through-hole reliability

• Compatible with lead-free assembly (260°C+ reflow)

• CAF (Conductive Anodic Filament) resistant

• Compatible with IPC-4101/98, /99, /101, /126 specifications

• Available in multiple dielectric constants (Dk): 3.92 @ 1 GHz / 3.79 @ 10 GHz (typical)

Typical Applications:

• Network switches, routers, and servers

• High-layer-count backplanes (20L+)

• Telecommunications infrastructure (5G base stations)

• Industrial control and instrumentation

• Medical electronics

• Aerospace and defense multilayer PCBs

3. Isola 408HR – Enhanced Performance for High-Speed Digital & RF Designs

Isola 408HR is a high-performance FR-4 laminate system engineered for superior signal integrity and thermal performance. It is the upgraded successor to the legacy FR408 and is specifically designed to handle the demands of high-speed digital and RF/microwave circuits.

Key Features:

• High Tg (180°C DSC, 175°C TMA)

• Excellent Dk/Df stability across frequency (3.70 @ 1 GHz)

• Low loss tangent (Df 0.009 @ 1 GHz) — ideal for high-speed signals

• Improved thermal conductivity for better heat dissipation

• Lead-free assembly compatible

• IPC-4101/26, /28, /29 specifications

• Excellent CAF resistance and thermal reliability

Typical Applications:

• High-speed digital backplanes and line cards

• RF and microwave circuits

• Servers, storage, and supercomputing

• Test and measurement equipment

• High-frequency communication devices
