Double-sided blackened gold plated board, featuring advanced black solder mask technology combined with double-sided gold plating treatment. The black surface presents a fine matte texture, offering both high appearance quality and line concealment. It effectively avoids reflection interference and is suitable for visualization scenarios of precision electronic devices. The gold plating layer has excellent electrical conductivity, is resistant to oxidation, wear-resistant, and has low contact resistance, ensuring high-frequency welding and long-term stable operation. The double-sided circuit layout supports streamlined and efficient functional design, with precise control of line width and spacing down to fine specifications. It is compatible with surface mount and through-hole mixed packaging and is suitable for integration of various electronic components. Using high Tg FR-4 substrate, it undergoes rigorous reliability tests such as high and low temperature cycling and humidity aging, and is suitable for complex working environments. The product takes into account customization of appearance, performance stability, and process compatibility. Its core advantages focus on "gold plating durability + precise manufacturing". It is widely used in smart wearable devices, high-end communication modules, industrial detection instruments, etc., and is a high-quality PCB solution that balances appearance quality and practicality and meets the requirements of mid-to-high-end electronic devices.
