Double-sided blue gold-plated boards, featuring a high-saturation blue solder mask layer combined with double-sided gold plating technology, have a unique blue appearance that combines visual recognition and product differentiation advantages. They are suitable for the appearance customization requirements of high-end electronic devices. The gold-plated surface has excellent electrical conductivity, resistance to oxidation and wear, which can ensure high-frequency welding and long-term stable operation, effectively reducing contact resistance and signal loss. The double-sided circuit layout supports streamlined functional design, with precise control of line width and spacing, and is compatible with surface mount and through-hole packaging, meeting the circuit requirements of small and medium-power electronic devices. The core advantages lie in the blue customized appearance, high reliability of gold plating, and the practical adaptability of the double-sided layout. They are widely used in smart wearable devices, high-end consumer electronic accessories, communication modules, etc., and are a high-quality PCB solution that balances appearance customization and practical performance.

This double-sided PCB combines a blue solder mask with a customer-specified gold-plating process. Gold plating may be applied to designated areas according to the product design. The exact plating process, coverage, and thickness must be confirmed from the customer drawing or technical specification.
Q: What is the gold-plating thickness?
A: The thickness should be specified in the customer drawing, purchase specification, or mutually approved technical documentation.
