In today’s fast-paced electronics landscape, the demand for high-performance printed circuit boards (PCBs) is at an all-time high. Our double-sided PCB, constructed from F4BM220 material, stands out as a premium choice for a variety of applications, offering remarkable thermal and electrical properties.
Material Selection: F4BM220
At the core of this double-sided PCB is F4BM220, a high-performance laminate known for its superior electrical characteristics. This material is engineered through a meticulous process that combines fiberglass cloth with polytetrafluoroethylene (PTFE) resin, resulting in a product that surpasses traditional FR-4 materials.
Key Features of F4BM220:
- Dielectric Constant (Dk): 2.2±0.04 at 10GHz, ensuring minimal signal loss, which is crucial for high-frequency applications.
- Dissipation Factor: 0.001 at 10GHz, contributing to higher efficiency and better signal integrity.
- Thermal Performance: With a CTE of 25 ppm/°C in the X-axis and 34 ppm/°C in the Y-axis, F4BM220 maintains dimensional stability across varying temperatures.
- Moisture Absorption: Less than 0.08%, which enhances reliability in humid conditions.
- Flammability Rating: UL-94 V0, ensuring compliance with safety standards.
