OK Industries remains one of the leading industrial suppliers of wire wrap tools and supplies. Bell Telephone Laboratories developed the system, and OK Industries, which was founded in 1946, pioneered the process. Simple it's a wire connection system that uses a special tool to tightly wrap a small gauge solid wire around the sharp corners of a connection post.
A system back plane with thousands of wire terminations is typically completed in a few days. Nimble-fingered production assemblers, armed with pneumatic wire wrap guns, an assortment of pre-stripped wires, and computer printouts of wiring charts, are amazingly fast and accurate. It is ideal for complex one-of-a-kind circuits and systems.
Wire wrap has been successfully used for decades by the telecom/datacom and controls industries. It's relatively fast, reliable, simple, solderless, inexpensive, and easy to learn. There is another alternative … wire wrap.
PC board fabrication is not necessarily the next step. Part way into the project, too many connections too close together turn it into an unmanageable mess.Ĭonstruction articles found in electronics magazines use printed circuit boards for all but the simplest circuits, so investing time and money into the PC board fabrication process seems to be the next logical step, albeit a bit daunting for the new hobbyist. The neophyte soon finds out that assembling a more complex circuit onto perf board is an exercise in futility. They find it's time to move on to bigger and better circuits. Electronics hobbyists evolve through a series of circuit-building techniques, starting with the simplest of the simple, such as wire nuts or twisting component leads together, to designing, fabricating, and assembling their own printed circuit boards.Īfter successfully building a few simple circuits on perf board, and perhaps a small kit or two, confidence rises.
