A modern solderless breadboard socket ( Invented by Ronald J Portugal for E&L Instruments and Derby CT ) consists of a perforated block of plastic with numerous tin-plated phosphor bronze or nickel silver alloys spring clips under the perforations.

Originally the word referred to a literal breadboard because of the polished piece of wood used for slicing bread.

A breadboard is a construction base for the prototyping of electronics.

In the 1970s the solderless breadboard became available.

This makes it easy to use for creating temporary prototypes and experimenting with circuit design and for this reason.

Solderless breadboards are also popular with students and in technological education.

Older breadboard types did not have this property.

Alternatives

Alternative methods to create prototypes are point-to-point construction (reminiscent of the original wooden breadboards), wire wrap, wiring pencil, and boards like the stripboard.

Complicated systems, such as modern computers comprising millions of transistors, diodes, and resistors, do not lend themselves to prototyping using breadboards, as their complex designs can be difficult to layout and debug on a breadboard.

Modern circuit designs are generally developed using a schematic capture and simulation system and tested in software simulation before the first prototype circuits are built on a printed circuit board.

Integrated circuit designs are a more extreme version of the same process: since producing prototype silicon is costly, extensive software simulations are performed before fabricating the first prototypes.

However and still prototyping techniques are still used for some applications such as RF circuits, or where software models of components are inexact or incomplete.

It is also possible to use a square grid of pairs of holes where one hole per pair connects to its row and the other connects to its column.

This same shape can be in a circle with rows and columns each spiralling opposite clockwise/counterclockwise.
