Juotoslevyt, also known as printed circuit boards (PCBs), are the backbone of modern electronics. They provide a mechanical foundation for electronic components and electrically connect them using conductive pathways, traces, and pads etched from copper sheets laminated onto a non-conductive substrate. This substrate is typically made of fiberglass-reinforced epoxy resin (FR-4), although other materials like phenolic or Teflon are used for specific applications.
The manufacturing process involves several steps. First, a design is created using specialized software, which dictates
PCBs can range from single-sided boards with components on one side and traces on the other, to
