TMM3 Microwave PCB
Introduction
Rogers TMM3 thermoset microwave material is a ceramic thermoset
polymer composite specifically engineered for strip-line and
micro-strip applications requiring high plated thru-hole
reliability.
TMM3 laminates offer a unique blend of advantages found in both
ceramic and traditional PTFE microwave circuit laminates,
eliminating the need for complex production techniques associated
with these materials. These laminates leverage thermoset resins,
ensuring exceptional reliability for wire-bonding processes while
mitigating concerns such as pad lifting or substrate deformation.
Features & Benefits
TMM3 laminates possess a dielectric constant (Dk) of 3.27 +/- .032,
ensuring precise and consistent signal transmission, exhibiting a
dissipation factor of just .002 at 10GHz. This low dissipation
factor ensures that the PCBs experience minimal signal loss,
enabling efficient and effective communication within the
circuitry.
The thermal coefficient of Dk is 37ppm/°K, providing stability even
in varying temperature conditions. Moreover, the coefficient of
thermal expansion is precisely matched to copper, mitigating
potential issues related to thermal stress.
TMM3 materials possess mechanical properties that resist creep and
cold flow, ensuring long-term reliability. They are also resistant
to process chemicals, reducing the risk of damage during
fabrication. Additionally, it eliminates the need for a sodium
napthanate treatment prior to electroless plating, streamlining the
manufacturing process.
