Unperforated Prototype Boards7

Unperforated prototype board products are commonly used to construct customized printed circuit boards for interconnecting electronic components in a hobby or developmental context. Typically consisting of a sheet of fiberglass-reinforced epoxy resin that is coated on one or both sides with a layer of copper, materials are available pre-coated with a photosensitive material for use with photographic pattern reproduction techniques, or without such a coating to accommodate production processes based on computer-controlled machining operations.
