What i a Solderle Breadboard?

Definition and Hitory

A olderle breadboard i a contruction bae ued to build emi-permanent prototype of electronic circuit. Unlike perfboard or tripboard, breadboard do not require oldering or detruction of track, making them highly reuable. The term "breadboard" originate from the early day of radio, when amateur would nail bare copper wire or terminal trip to a wooden board, often literally a bread cutting board, to create imple circuit.

In 1960, Orville Thompon of DeVry Technical Intitute patented the firt olderle breadboard, which ued pring metal to connect row of hole together. Thi deign wa further refined in 1971 by Ronald Portugal of E&L Intrument, who introduced a concept with hole in 0.1-inch (2.54 mm) pacing, aligning with DIP IC package. The modern olderle breadboard we ue today i a direct decendant of thee early innovation.

Baic Component and Functionality

A modern olderle breadboard ocket conit of a perforated block of platic with numerou tin-plated phophor bronze or nickel ilver alloy pring clip under the perforation. Thee clip, often called tie point or contact point, connect component and wire inerted into the hole. The pacing between the clip (lead pitch) i typically 0.1 inche (2.54 mm), allowing IC in dual in-line package (DIP) to be inerted to traddle the centerline of the board.

Interconnecting wire and the lead of dicrete component uch a capacitor, reitor, and inductor can be inerted into the remaining free hole to complete the circuit. The clip are rated for 1 ampere at 5 volt and 0.333 ampere at 15 volt (5 watt), providing a reliable connection for mot electronic component.
