Terminal strips The main areas, to hold most of the electronic components. Strips consist of interconnected electrical terminals. The layout of a typical solderless breadboard is made up from two types of areas, called strips. Solderless breadboards connect pin to pin by metal strips inside the breadboard. The edge of the board has male and female dovetail notches so boards can be clipped together to form a large breadboard. Typically the spring clips are rated for 1 ampere at 5 volts and 0.333 amperes at 15 volts (5 watts). Where ICs are not used, discrete components and connecting wires may use any of the holes.

Interconnecting wires and the leads of discrete components (such as capacitors, resistors, and inductors) can be inserted into the remaining free holes to complete the circuit. Integrated circuits (ICs) in dual in-line packages (DIPs) can be inserted to straddle the centerline of the block. The spacing between the clips (lead pitch) is typically 0.1 inches (2.54 mm). The number of tie points is often given in the specification of the breadboard. The clips are often called tie points or contact points. Design Ī modern solderless breadboard socket (invented by Ronald J Portugal for E&L Instruments, Derby CT) consists of a perforated block of plastic with numerous tin plated phosphor bronze or nickel silver alloy spring clips under the perforations. The breadboard most commonly used today is usually made of white plastic and is a pluggable (solderless) breadboard. Both examples refer to and describe other types of breadboards as prior art.

US Patent 3,496,419, was filed in 1967 and refers to a particular printed circuit board layout as a Printed Circuit Breadboard.

For example, US Patent 3,145,483, was filed in 1961 and describes a wooden plate breadboard with mounted springs and other facilities. Using thumbtacks or small nails as mounting posts was also common.īreadboards have evolved over time, with the term now being used for all kinds of prototype electronic devices. Sometimes a paper schematic diagram was first glued to the board as a guide to placing terminals, then components and wires were installed over their symbols on the schematic. In the early days of radio, amateurs nailed bare copper wires or terminal strips to a wooden board (often literally a board to slice bread on) and soldered electronic components to them.
