PCB Surface Finishes
What is PCB surface finishes?
PCB surface finishes, also known as PCB surface treatments, involve applying a layer of metal or compound to the copper pads of a printed circuit board through chemical or physical methods. These finishes serve two key functions:
Prevention of Copper Pad Oxidation – Protecting the copper from oxidation to ensure long-term reliability.
Enhancing Solderability – Making it easier to solder electronic components onto the PCB.
At Gold Mate, we use the latest surface finish technologies to ensure the highest quality and performance for your PCBs.
