Prototype circuit boards are generally assembled by an electronics engineer rather than an assembly line worker or technician.
Building an actual circuit to verify that the theoretical design works. Prototype microprocessor circuits are generally debugged with specially written diagnostic code.
Production ：Following the pilot run there will likely be changes to the software, and possibly the circuit design, as the unit develops into a stable, final product.
To test the product further, a small quantity of units ( Perhaps 25 or 50 ) are field trialed. Product performance and functionality are tested to assure that the product performs and meets the design specifications.
