During the development stage, several working electronic prototypes may be produced, usually by hand, and are tested by our engineers.
The electronic prototypes are then sent to our client for further testing in the field to gather feedback and to identify bugs that will later be corrected.
Once an electronic prototype has undergone sufficient testing and validation, a pre-production prototype is then marked as the “sample”.
This is then used as the benchmark or standard to which mass-produced units will be compared. This golden sample is also used for certification purposes and sent to a third-party testing facility for CE, UL, FCC, or ROHS markings.
