Rogers TC350 is a ceramic-filled, PTFE-based laminate reinforced with woven glass for high-frequency PCB applications. It combines a dielectric constant of 3.50 ± 0.05, a dissipation factor of 0.0020 at 10 GHz, and thermal conductivity of 0.72 W/m·K.
These characteristics support you with reliable high-frequency signal performance and effective heat dissipation. It is well-suited for medical RF hardware such as imaging systems and RF surgical equipment.
MedPCB produces custom Rogers TC350 PCBs for medical RF and high-power electronics, including multilayer and hybrid stack-up projects.

An unverified or substituted laminate can fail Dk/Df verification and compromise RF qualification.
Our Solution: MedPCB maintains controlled storage for ceramic-filled PTFE, tracks every lot to its certificate of conformance, and verifies Dk/Df against the Rogers TC350 datasheet before cutting.
High-power medical RF circuits can concentrate heat in compact areas, making thermal design and heat spreading important for reliable operation.
Our Solution: During DFM review, we evaluate thermal requirements and recommend suitable PCB construction options, including heavy copper, copper coins, thermal via arrays, and busbar integration where applicable. These approaches help improve heat spreading and current-carrying capability in your high-power medical PCB projects.
PTFE is soft, hydrophobic, and dimensionally sensitive, which can make drilling, surface treatment, and plating more demanding than conventional FR-4 fabrication.
Our Solution: MedPCB uses controlled PTFE-compatible surface finish and metallization processes to promote reliable copper adhesion and plated-through-hole performance.
Even slight over-etch shifts impedance and degrades return loss on high-frequency lines.
Our Solution: MedPCB controls etch processes tightly, places impedance coupons on every panel, and verifies lines to ±10% (for 50 Ω and above) or ±5 Ω (below 50 Ω) by TDR, with solder mask skip zones over RF traces where specified.
Rogers TC350 is a ceramic-filled PTFE laminate designed for high-frequency applications where stable dielectric performance, low RF loss, and thermal management are important. These properties make it suitable for medical RF equipment such as MRI systems, RF ablation devices, and diathermy equipment.
