wirewrap

Wirewrap is a metalworking technique that involves bending and twisting small-gauge wire around components to create secure, durable connections. Originating in the early 20th century, it was widely used in electronics assembly before being largely replaced by soldering and modern connector systems. Despite its decline in industrial applications, wirewrap remains a popular method among hobbyists, educators, and artists for its simplicity and versatility.

The process begins with a wirewrap pin, a small metal post with evenly spaced holes, which serves as the connection point. A thin, soft metal wire—typically copper or aluminum—is wrapped around the pin in a spiral pattern, creating a tight, friction-based bond. The wire is bent at a 90-degree angle before being inserted into the pin, then twisted clockwise to secure it. This method ensures a stable connection without the need for soldering or additional hardware.

Wirewrap is favored for its ease of use, especially in educational settings, as it allows for quick prototyping and disassembly. It is also used in jewelry making, where wire is wrapped around beads or other materials to form intricate designs. In electronics, wirewrap was particularly useful for breadboarding circuits, as it provided a flexible and reusable way to connect components. However, its reliance on manual labor and lack of long-term reliability in harsh environments led to its decline in professional settings.

Today, wirewrap is often associated with retro computing and vintage electronics, where enthusiasts restore and modify older machines. It continues to be taught in schools as a fundamental skill in metalworking and electronics. While not as common as it once was, wirewrap remains a valuable technique for those seeking a hands-on, low-tech approach to connection and construction.
