2-Layers Rigid PCB No Silkscreen & Blue Solder Mask

Rigid PCBs are the most commonly used type of printed circuit boards, as they are the most efficient for simple circuits with few components. They are made from a single layer of rigid material, usually, fiberglass or resin, with copper tracks etched into it. This type of PCB is suitable for most basic applications, such as small consumer electronics, medical devices, and automotive components.
