154:. It is a thin, rigid sheet with holes pre-drilled at standard intervals across a grid, usually a square grid of 0.1 inches (2.54 mm) spacing. These holes are ringed by round or square copper pads, though bare boards are also available. Inexpensive perfboard may have pads on only one side of the board, while better quality perfboard can have pads on both sides (
240:, nearby holes aren't connected, and the only hole in a pad is already occupied by a component's lead. Wires used range from isolated wires, including verowire (enameled copper wire with a polyurethane insulation supposed to melt when soldered), to bare copper wire, depending on individual preference, and often also on what is currently at hand in the workshop.

layout can often be used to generate perfboard layouts as well. In this case, the designer positions the components so all leads fall on intersections of a 0.1 inches (2.54 mm) grid. When routing the connections more than 2 copper layers can be used, as multiple overlaps are not a problem for

One school of thought advocates making as many connections as possible without adding extra wire. This is done by bending the existing leads on resistors, capacitors, etc. into position, trimming off extra length, and soldering the lead to make the required electrical connection. Another school of

in that each pad on perfboard is isolated. Stripboard is made with rows of copper conductors that form default connections, which are broken into isolated segments as required by scraping through the copper. This is similar to the pattern of default connections on a solderless

Once the layout is finalized, the components are soldered in their designated locations, paying attention to orientation of polarized parts such as electrolytic capacitors, diodes, and integrated circuits. Next, electrical connections are made as called for in the layout.
251:. A special stripping tool can be used, incorporating a thin steel blade with a slit that the wire is simply inserted into and then pulled loose, leaving a clean stripped end. This wire was developed initially for circuit assembly by the
290:. However, the absence of default connectivity on perfboard gives the designer more freedom in positioning components and lends itself more readily to software-aided design than stripboard or breadboard.

thought refuses to bend the excess leads of components and use them for wiring, on the grounds that this makes removing a component later hard or impossible, e.g. when a repair is needed.

Intentional solder bridges can be used to connect adjacent pads when necessary. Careful hand–eye coordination is needed to avoid causing inadvertent short circuits.
