PCB Stackup

The TLX-7 PCB features a simple yet highly efficient 2-layer stackup:

• Copper Layer 1: 35μm (1oz) for signal transmission and routing.
• TLX-7 Core: 0.762mm (30mil) thickness, providing a low dielectric constant (Dk=2.6Dk​=2.6) and stable electrical performance over a wide temperature range.
• Copper Layer 2: 35μm (1oz) for grounding and signal integrity.

Taconic TLX-7 Laminate Overview

The TLX-7 laminate is a PTFE-based, fiberglass-reinforced material engineered for high-frequency and microwave applications. Known for its low dielectric constant (Dk=2.6Dk​=2.6) and extremely low dissipation factor, it minimizes signal loss and ensures consistent performance up to millimeter-wave frequencies.

Key Features:

• Dielectric Constant (DkDk​): 2.6 (low and stable over temperature and frequency).
• Dissipation Factor (DF): Extremely low, ensuring minimal signal loss.
• Dimensionally Stable: Reliable mechanical properties for demanding designs.
• Thermal Stability: Excellent performance under thermal stress.
• Low Moisture Absorption: Suitable for use in humid or harsh environments.
• UL 94 V-0 Rating: Fire-resistant and safe for industrial applications.

The combination of these properties makes TLX-7 laminate an ideal choice for low-layer count, high-frequency PCBs.
