15mil Rogers TMM6 PCB DK6.0 Double-layer ENEPIG 1oz Bare Copper

In the demanding world of high-frequency and microwave electronics, the substrate material and construction integrity of a Printed Circuit Board (PCB) are not merely choices but critical determinants of system performance. We present a precision-engineered double-layer DK6.0 PCB crafted from Rogers TMM6, a premier ceramic thermoset composite, designed explicitly for applications where electrical stability, thermal management, and high reliability are non-negotiable. This board exemplifies a perfect synergy between advanced material science and meticulous fabrication, featuring a 15mil (0.381mm) core and an Electroless Nickel Electroless Palladium Immersion Gold (ENEPIG) surface finish. Tailored for strip-line and micro-strip designs, it offers a stable dielectric constant (Dk=6.0) and excellent plated through-hole reliability, making it an ideal, robust foundation for sensitive RF and microwave circuitry.

Advanced Material: Rogers TMM6

The heart of this PCB is Rogers TMM6, a ceramic thermoset polymer composite. It bridges the gap between the performance of traditional PTFE materials and the processability of standard epoxy systems. With a tightly controlled dielectric constant (Dk) of 6.00±0.08 at 10 GHz and a low dissipation factor (Df) of 0.0023, it ensures minimal signal loss and consistent phase stability. Its coefficient of thermal expansion (CTE) is matched to copper, dramatically enhancing plated through-hole reliability by minimizing stress during thermal cycling. Furthermore, its high decomposition temperature (Td > 400°C) and resistance to process chemicals make it exceptionally robust during fabrication and assembly, including wire bonding processes enabled by its thermoset resin base.

Key Features & Benefits for Your Application

1) Stable Electrical Performance: The low thermal coefficient of Dk (-11 ppm/°K) ensures consistent electrical properties across a wide temperature range, crucial for outdoor and automotive applications.

2) Enhanced Reliability: Copper-matched CTE (X/Y: 18 ppm/K, Z: 26 ppm/K) and robust thermoset chemistry prevent via cracking and delamination, meeting IPC-Class-2 standards as a minimum.

3) Superior Processability: Unlike some high-frequency materials, TMM6 is compatible with all standard PCB fabrication processes (drilling, plating, etching), reducing manufacturing complexity and cost.

4) Premium Surface Finish–ENEPIG: This finish provides a flat, wire-bondable surface with excellent shelf life. The nickel provides a diffusion barrier, the palladium prevents nickel corrosion ("black pad" syndrome), and the gold ensures superior solderability and contact resistance.

5) Global Availability & Support: Supported by a worldwide supply chain and fabrication network, this board is available for prototyping and volume production.
