The Arlon 35N Polyimide PCB is a premium 4-layer printed circuit board engineered for high-reliability down-hole tools and severe thermal environments. Built using Arlon 35N polyimide resin material, this circuit board offers exceptional thermal stability and a high glass transition temperature ($T_g$) of 250°C. Designed to withstand prolonged exposure to elevated temperatures and mechanical stress, it provides the robust electrical performance required by oil and gas exploration, aerospace telemetry, and heavy industrial instrumentation.
Key Features of Arlon 35N Polyimide PCB
-
Material Matrix: Pure polyimide resin system (Arlon 35N) with a $T_g$ of 250°C for superior thermal survival.
-
Layer Count: 4-layer rigid construction optimized for complex signal routing in compact down-hole enclosures.
-
Thermal Decomposition: $T_d$ rating of 407°C, ensuring high resistance to delamination during assembly and field operation.
-
Low Z-Axis Expansion: Minimal Z-axis thermal expansion ($1.2\%$ between 50°C and 250°C) to maintain plated through-hole (PTH) integrity.
-
Flammability Rating: UL 94 V-0 compliant for stringent safety environments.
-
Controlled Impedance: Precision etching tolerances to support reliable high-frequency data transmission.
Applications
-
Energy Exploration: Down-hole drilling tools, Measurement While Drilling (MWD) systems, and Logging While Drilling (LWD) equipment.
-
