TP450 PCB 2-Layer TP-series Laminates 2.5mm Thick Bare Copper

TP450 PCB 2-Layer TP-series Laminates 2.5mm Thick Bare Copper

Product Overview

The TP450 PCB is a high-performance 2-layer rigid printed circuit board designed for demanding high-frequency applications. Built with TP450 PCB laminate, this PCB offers exceptional dielectric stability, low signal loss, and high reliability in extreme environments. With a finished thickness of 2.6mm, 1oz copper weight, and ENIG (Electroless Nickel Immersion Gold) surface finish, this board is ideal for aerospace, military, and advanced RF applications.

Engineered for precision, the 2-layer TP450 PCB features a 6/4 mil trace/space capability and supports 0.5mm minimum hole size, ensuring robust signal integrity. The glass-free thermoplastic construction provides superior thermal and mechanical stability, making it suitable for missile systems, satellite navigation, and antenna designs.

Key Features & Benefits

• Dielectric Constant (Dk): 4.5±0.2 @ 10GHz (stable across frequencies)
• Ultra-Low Loss Tangent (Df): 0.0010 @ 10GHz (minimizes signal attenuation)
• Low CTE (Coefficient of Thermal Expansion):
• -X/Y-axis: 50 ppm/°C
• -Z-axis: 60 ppm/°C (prevents warping under thermal stress)
• Thermal Conductivity: 0.44 W/mK (effective heat dissipation)
• Moisture Absorption: 0.01% (excellent humidity resistance)
• UL 94-V0 Flame Retardant (meets stringent safety standards)

PCB Construction Details

The 2.5 mm TP450 PCB is constructed with a high-frequency thermoplastic core, ensuring excellent signal integrity and thermal performance. Below are the detailed specifications:

PCB Stackup

The PCB stackup consists of athick TP450 PCB core with symmetrical copper layers for balanced signal transmission.

PCB Statistics

The TP450 PCB board supports a moderate component density with a mix of through-hole and SMT pads.

Additional Technical Information
