Hey there is your answer.... hope it helps u ☺
The most common use of the word prototype is a functional, although experimental, version of a non-military machine (e.g., automobiles, domestic appliances, consumer electronics) whose designers would like to have built bymass production means, as opposed to amockup, which is an inert representation of a machine's appearance, often made of some non-durable substance.
An electronics designer often builds the first prototype from breadboard or stripboard orperfboard, typically using "DIP" packages.
However, more and more often the first functional prototype is built on a "prototypePCB" almost identical to the production PCB, as PCB manufacturing prices fall and as many components are not available in DIPpackages, but only available in SMT packages optimized for placing on a PCB.
Builders of military machines and aviation prefer the terms "experimental" and "service test"
In electronics, prototyping means building an actual circuit to a theoretical design to verify that it works, and to provide a physical platform for debugging it if it does not. The prototype is often constructed using techniques such as wire wrapping or usingveroboard or breadboard, with the result being a circuit that is electrically identical to the design but not physically identical to the final product.[12]
Open-source tools like Fritzing exist to document electronic prototypes (especially the breadboard-based ones) and move toward physical production. Prototyping platforms such as Arduino also simplify the task of programming and interacting with amicrocontroller.[13] The developer can choose to deploy their invention as-is using the prototyping platform, or replace it with only the microcontroller chip and the circuitry that is relevant to their product.
A technician can quickly build a prototype (and make additions and modifications) using these techniques, but for volume production it is much faster and usually cheaper to mass-produce custom printed circuit boards than to produce these other kinds of prototype boards. The proliferation of quick-turn PCB fabrication and assembly companies has enabled the concepts of rapid prototyping to be applied to electronic circuit design. It is now possible, even with the smallest passive components and largest fine-pitch packages, to have boards fabricated, assembled, and even tested in a matter of days.
