Double-sided immersion gold FR4 PCB circuit board is a type of printed circuit board that has conductive patterns on both sides of the insulating substrate. The FR4 material refers to a flame-retardant epoxy laminate that is commonly used in PCB manufacturing. The immersion gold finish is a surface treatment applied to the PCB to protect the copper traces and provide a reliable electrical connection.
The use of double-sided PCBs allows for more complex circuit designs as the conductive patterns on both sides can be interconnected through metallization holes. This feature is particularly useful in medical applications where intricate circuitry is often required. The immersion gold finish provides several benefits, including excellent solderability, corrosion resistance, and a flat surface for component placement.
