9.1 TMM3 Thermoset Microwave CCL Introduction
Rogers TMM3 Copper Clad Laminate belongs to premium TMM series thermoset microwave composite substrates, formulated with integrated ceramic, hydrocarbon and thermoset polymer materials. Custom engineered for high plated-thru-hole reliability, this professional microwave laminate is perfectly suited for high-precision stripline and microstrip circuit designs in modern RF and microwave devices. Differing from traditional ceramic and PTFE laminates, TMM3 thermoset laminate merges the superior electrical performance of rigid ceramic substrates and the flexible processing advantages of soft circuit substrates, eliminating the need for complex, specialized manufacturing processes required by conventional high-frequency dielectric materials. Compatible with standard printed wiring board production flows and free of sodium napthanate pretreatment for electroless plating, TMM3 laminate delivers simplified production workflows and stable mass-production quality for 2-layer high frequency PCB fabrication.

9.2 Core Structural & Physical Properties of TMM3 CCL
•Ultra-Stable Thermal Dielectric Performance: TMM3 thermoset microwave laminate features an extremely low thermal coefficient of dielectric constant, consistently below 30 ppm/°C. This low thermal drift characteristic maintains stable Dk parameters in variable temperature environments, avoiding signal distortion and performance fluctuation for long-running microwave circuits.
•Copper-Isotropic Thermal Expansion Design: TMM3 laminate adopts isotropic thermal expansion coefficients highly synchronized with copper foil. This precise CTE matching greatly enhances plated through-hole reliability, lowers etching shrinkage rates during processing, and effectively prevents board warpage and structural failure of 100mil TMM3 high frequency PCB.
•Enhanced Thermal Conductivity: Thermal conductivity of TMM3 CCL reaches nearly twice that of conventional PTFE and ceramic composite laminates, enabling rapid and uniform heat dissipation for high-power RF circuits, power amplifiers and continuous-operation microwave systems.
•Permanent Thermoset Structural Stability: Built with pure thermoset resin matrix, TMM3 substrate will never soften under high-temperature working conditions. The rigid resin structure completely avoids pad lifting, substrate deformation and circuit damage during precision wire bonding assembly, ensuring high packaging yield and long-term device reliability.
•Excellent Process Chemical Resistance: Base substrate of TMM3 CCL offers strong resistance to common PCB etchants, organic solvents and manufacturing chemicals. It fully adapts to all standard PWB fabrication processes, effectively reducing substrate corrosion and mechanical damage during production and assembly.
