juotoslevy

Juotoslevy, also known as a perfboard or protoboard, is a type of electronic prototyping material used for building experimental circuits. It is typically a sheet of insulating material, commonly fiberglass or phenolic resin, that is pre-drilled with a grid of holes. These holes are spaced regularly, allowing for components to be easily inserted and secured.

The primary function of a juotoslevy is to provide a convenient and organized platform for assembling electronic components without the need for custom printed circuit boards (PCBs). Components such as resistors, capacitors, integrated circuits, and wires are typically soldered to the metal pads or eyelets surrounding the holes. The holes themselves can be used for component leads, jumpers, or wire connections.

Juotoslevyt are available in various sizes and hole patterns to accommodate different circuit designs and component densities. Some juotoslevyt feature pre-tinned pads, which facilitate soldering, while others require the user to create their own connections using wires or conductive traces. They are a staple in hobbyist electronics, educational settings, and for rapid prototyping in research and development. While not as permanent or professional as a custom PCB, juotoslevy offers a flexible and cost-effective solution for creating and testing electronic circuits.
