Definition

Taconic is a manufacturer of advanced PCB laminates for RF, microwave, and high-speed digital applications. Their product lines include TLY (low-loss PTFE/woven glass), RF-35 (ceramic-filled PTFE), and TLC (low-cost PTFE). Taconic materials are commonly specified alongside Rogers for high-frequency designs. TLY-5 offers Dk of 2.2 with Df below 0.001, suitable for millimeter-wave applications. Like Rogers PTFE materials, Taconic laminates require special surface preparation for copper adhesion and different processing than FR-4. Choose Taconic or Rogers based on specific Dk, Df, and cost requirements for your frequency range.
