Stripboard is the generic name for a widely used type of electronics prototyping material for circuit boards characterized by a pre-formed 0.1 inches (2.54 mm) regular (rectangular) grid of holes, with wide parallel strips of copper cladding running in one direction all the way along one side of an insulating bonded paper board.
Top of a copper clad Perfboard with solder pads for each hole. Perfboard is a material for prototyping electronic circuits.It is a thin, rigid sheet with holes pre-drilled at standard intervals across a grid, usually a square grid of 0.1 inches (2.54 mm) spacing.
In addition to the 32 mm standard, there are other but less frequently used systems (System 25, ip20 etc.). [ 1 ] [ 2 ] [ 3 ] The system allows reconfigurable shelf placement and spacing. The system was developed by fitting, machine and furniture manufacturers, and serves to standardize both component dimensions and production processes.
Recommended dimensions and layouts will vary with different building codes around the world, but some examples are: [4] [5] No leg of the triangle should be less than 1.2 m (4 ft) or more than 2.7 m (9 ft). The sum of all three sides of the triangle should be between 4–8 m (13–26 ft).
Eurocard is an IEEE standard format for printed circuit board (PCB) cards that can be plugged together into a standard chassis which, in turn, can be mounted in a 19-inch rack. The chassis consists of a series of slotted card guides on the top and bottom, into which the cards are slid so they stand on end, like books on a shelf.
Peg-Board is an expired trademark used as a brand name by the Masonite Corporation, first used in 1962, [1] which is often used as a generic term for perforated storage boards made of hardboard, wood, metal, or other material.

There is little evidence that the dimensions of these early racks were standardized. Telephone equipment racks (1923) The 19-inch rack format with rack-units of 1.75 inches (44.45 mm) was established as a standard by AT&T around 1922 in order to reduce the space required for repeater and termination equipment in a telephone company central ...
