Four-Layer Double-Sided Greenened Gold Semi-Hole Plate

A four-layer double-sided PCB board, employing advanced half-hole (half-buried hole) technology and green solder mask combined with electroless gold plating (ENIG) surface treatment, is specifically designed for high-end electronic products with strict requirements for space and reliability. Its core advantages lie in: The half-hole design achieves precise electrical connections at the module edges, significantly enhancing assembly density and integration; The electroless gold plating surface provides excellent flatness, weldability, and oxidation resistance for the pads, ensuring long-term reliability; The four-layer structure provides a stable power layer and a complete ground plane, effectively optimizing signal integrity and suppressing electromagnetic interference. This board is an ideal choice for communication modules, industrial control motherboards, high-end consumer electronics, and portable medical equipment, among others.
