Solderless Breadboard

Prototype without solder or tools.


Solderless breadboards make prototyping simple. Breadboards enables you to connect electronic components in thousands of ways to produce working circuits without soldering or damaging your circuit board — and you don't need additional tools. A breadboard is made up of formed metal sockets firmly secured in a durable plastic housing. The breadboard's grid pattern is a useful combination of isolated tie points serving as discrete points in the circuit as well as a continuous bus structure that distributes power and provides common ground points.

 

Our durable breadboards feature nickel-plated clips designed to withstand five thousand insertion cycles and come with an ample supply of jumper wires. Most models have heavy-duty aluminum backing and voltage and grounding posts. Ideal for educational electronics environments and prototype development.

Solderless Breadboard Basics

 

Solderless breadboards enable you to test your circuit design without wasting time soldering devices to an ordinary printed circuit board. If the circuit doesn't work properly, you simply change the circuit by removing components and jumper wires and reinserting them somewhere else or by replacing components.
 
A solderless breadboard is fabricated with hundreds of small contact holes (sometimes called tie points). These holes are spaced one-tenth of an inch apart, which matches the pin spacing of most integrated circuits, enabling you to insert all the integrated circuits directly into the breadboard.
 
Inside the plastic surface of the breadboard, each contact hole is connected to one another in a specific pattern that makes it easy to fabricate any circuit design. The holes in the center sections of the breadboard are connected in groups of five called terminal strips. The terminal strips are arranged in seperate groups depending on the size of the breadboard. Between the groups is an open slot in which you can connect components including resistors, diodes, capacitors, and integrated circuits.
 
The terminal strips are not connected across this ditch, meaning each row is electrically isolated. One strip connects to the holes labeled "A" to "E" and the other connects holes "F" to "J". You can position an integrated circuit so that it bridges the ditch, thus electically isolating each side of the component. Solderless breadboards feature additional groups of holes called bus strips. There are two bus strips on the outside of each section. You can use the bus strip on one side of the circuit for the voltage input source and the bus strip on the other side for the ground circuit.
 
Most solderless breadboards are logically labelled with numbers and letters in bright colors that help you easily line up the individual connection holes. The rows are generally numbered "1" to "30" and each column is labelled with letters "A" through "J".
