Double-sided PCB
When single-sided space is insufficient for complex circuit interconnection requirements, double-sided PCBs offer a classic and efficient solution. They form conductive traces on both sides of an insulating substrate and interconnect layers through metallized vias, freeing circuit design from the constraints of a single surface and significantly enhancing layout freedom.
Take this double-sided gold-plated PCB as an example, and it exemplifies the superior craftsmanship of this type of circuit board. Its core utilizes Shengyi brand FR-4 material, which offers excellent electrical insulation and mechanical strength. With a 1.6mm board thickness, the 36µm finished copper thickness ensures ample current-carrying capacity.
This board's manufacturing highlights its precise trace design (0.15mm line width/0.12mm line spacing) and minimum drilling depth of 0.3mm, meeting the requirements of high-density wiring. Its surface is treated with electroless nickel-gold plating, providing a flat soldering surface and excellent oxidation resistance, making it ideal for subsequent placement of precision components. The royal blue solder mask and white text complement each other, lending the product a unique appearance while ensuring clear and legible markings.
This mature and reliable structure makes double-sided PCB an ideal choice for achieving a balance between stable performance and cost-effectiveness in various fields such as industrial control, automotive electronics and smart home appliances.
