Introduction to ISOLA 370HR

The ISOLA 370HR is designed specifically for multilayer PCB applications where thermal performance and reliability are paramount. Utilizing a patented high-performance 180°C Tg FR-4 multifunctional epoxy resin system by Polyclad, this PCB is suitable for complex and demanding electronic environments. Its construction features high-quality E-glass glass fabric, which significantly enhances Conductive Anodic Filament (CAF) resistance, a critical factor in ensuring long-term operational integrity.

Key Properties and Attributes

1. Thermal Performance

One of the standout features of the ISOLA 370HR is its Glass Transition Temperature (Tg) of 180°C. This high Tg value ensures that the PCB can operate efficiently under elevated temperatures without compromising its structural integrity. Coupled with a thermal conductivity of 0.4 W/MK, users can expect optimal heat dissipation, reducing the risk of overheating in high-density applications.

2. Mechanical and Chemical Resilience

The ISOLA 370HR exhibits exceptional mechanical properties, including a low Coefficient of Thermal Expansion (CTE), which measures how much a material expands with temperature changes. With a pre-Tg CTE of 45 ppm/°C in the Z-axis and 13/14 ppm/°C in the X/Y-axis, it minimizes the potential for warping and delamination during thermal cycling. Additionally, the PCB showcases impressive moisture absorption of just 0.15%, enhancing its reliability in humid environments.

3. Electrical Performance

The dielectric properties of the ISOLA 370HR are tailored for high-frequency applications. It boasts a dielectric constant (DK) of 3.92 at 5 GHz and a loss tangent (Df) of 0.025 at the same frequency, ensuring minimal signal loss and optimal performance in communication devices and other high-speed applications.

4. Flammability and Safety Standards

Safety is a critical concern in PCB manufacturing. The ISOLA 370HR meets the stringent UL94-V0 flammability rating, indicating its resistance to ignition and the ability to self-extinguish in the event of a fire. This attribute is especially vital for applications in the automotive, medical, and aerospace sectors.

PCB Stackup and Construction
This ISOLA 370HR PCB features a 6-layer stackup with a total thickness of 1.6mm, ensuring optimal signal integrity and power distribution. It includes four signal layers (Top, SIG1, SIG2, Bottom) and two plane layers (GND and PWR). The finished copper weight is 1 oz (1.4 mils) for both inner and outer layers, and the surface finish is ENIG, providing excellent solderability and corrosion resistance.

Dimensional Accuracy
The board dimensions are 40mm x 55mm, with a tolerance of +/- 0.15mm. It supports a minimum trace/space of 4/4 mils and a minimum hole size of 0.2mm. These precise measurements ensure reliable performance in complex electronic applications.
