RT/duroid 5880LZ PCB: Key Properties, Customization, and High-Performance Uses

In high-performance electronics, PCB material selection defines a product’s functionality—especially for high-frequency or weight-constrained designs.Rogers RT/duroid 5880LZ laminates stand out as filled polytetrafluoroethylene (PTFE) composites, engineered explicitly for demanding strip-line and micro-strip circuits. Their unique formulation solves two critical challenges: delivering top-tier electrical performance while keeping components lightweight—a must for industries like aerospace and defense.

The laminate’s specialized filler is its defining feature, enabling low density and a lightweight profile. For applications where every gram impacts efficiency (e.g., airborne systems), this trait is transformative. It lets engineers design high-performance circuits without compromising weight limits, makingRT/duroid 5880LZ a go-to for weight-sensitive, high-performance needs.

Core Properties of RT/duroid 5880LZ

Rogers 5880LZ’s reputation stems from properties tailored to fix common electronic design pain points.

First, its low dielectric constant (Dk) of 2.00 +/- 0.04 minimizes signal delay and loss in high-frequency circuits—critical for clear data/power transmission. What makes this stand out is consistency: Dk is uniform across panels and stable over a wide frequency range, ensuring reliability for multi-band systems.

Complementing this is a low dissipation factor (0.0021–0.0027 at 10GHz). This measures energy lost as heat; a low value means minimal waste, which is vital for radar or satellite systems where efficiency dictates operational range.

Thermal stability is another strength, thanks to a low Z-axis coefficient of thermal expansion (CTE) of 40 ppm/°C. Z-axis CTE controls vertical expansion, protecting plated through-holes (PTHs) from cracking during temperature fluctuations—essential for harsh environments like aerospace thermal shocks.

Its low density (1.4 gm/cm³) reinforces weight efficiency, while exceptional chemical resistance ensures durability during manufacturing. It withstands solvents/reagents used in etching/plating (hot or cold) without degrading structural or electrical integrity.
