In the rapidly evolving field of optical communication, where high - speed and reliable data transmission are paramount, our 6 - layer Optical Module PCBs are designed to meet the most stringent requirements. These PCBs are constructed using EM - 890K material, which offers exceptional electrical properties, including low dielectric loss and high signal - to - noise ratio, making it an ideal choice for optical module applications.
The board thickness of 1.65mm and a thickness ratio of 8:1 are carefully engineered to balance mechanical strength and signal performance. The 6 - layer structure provides ample space for complex circuit designs, enabling the integration of multiple optical and electrical components on a single board.
One of the key features of our PCBs is the through - hole POFV (Plugged Over Via Full) technology. By filling the vias, it effectively prevents the entry of moisture and contaminants, reducing the risk of electrical shorts and improving the overall reliability of the PCB. This is especially crucial in optical modules, where any signal disruption can lead to data loss or system failure.
The minimum aperture of 0.2mm and minimum trace width/spacing of 267/96μm allow for high - density circuit layouts, facilitating the miniaturization of the optical module while maintaining high - performance signal transmission.
The surface treatment combines electrolytic hard gold and Immersion Gold (ENIG). Electrolytic hard gold provides excellent wear resistance and low contact resistance, ensuring reliable electrical connections for components that are frequently plugged and unplugged. ENIG offers good corrosion resistance and solderability, enhancing the long - term reliability of the PCB in various operating environments.
