Introducing the ISOLA 370HR PCB, a state-of-the-art solution
designed for high-performance multilayer applications. Engineered
with a patented 180°C Tg FR-4 multifunctional epoxy resin system by
Polyclad, the 370HR laminates and prepregs excel in thermal
performance and reliability, making them the ideal choice for
demanding environments.
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.
Typical Applications
The ISOLA 370HR is not just a technical achievement; it is a
versatile solution that finds applications in various sectors,
including:
- Computing, Storage & Peripherals: Ideal for high-performance
computer components that require reliable thermal management.
