TPH-1/2: A Revolutionary Laminate for Microwave Circuits
Unmatched Performance and Reliability
TPH-1/2 stands out in the microwave circuit industry due to its unique composition of both inorganic and organic materials, combined with a special process and compounding. This innovative approach results in a substrate that offers several key advantages:
Advanced Design Features:
- Thermal Stability: The black substrate boasts a dielectric constant of 2.65, maintaining consistent performance across broad temperature (-100°C to +150°C) and frequency ranges.
- Enhanced Peel Strength: Superior adhesion between copper and the substrate compared to traditional ceramic vacuum film coatings, facilitating easier circuit processing, higher production pass rates, and significantly reduced manufacturing costs.
- Low Dissipation Factor: With tgδ≤1*10^-3, minimal loss variations occur with increasing frequency, ensuring efficient signal transmission.
- Mechanical Versatility: Ease of mechanical manufacturing processes such as drilling, punching, grinding, cutting, and etching, unmatched by ceramic substrates.
- Weight Advantage: The lower specific gravity contributes to lighter module weights, a distinctive feature not achievable with other materials.
