The sample phase is the initial production stage of electronic devices, such as displays or HMI components, where a short test series is manufactured based on the approved design. Its purpose is to verify construction accuracy, manufacturing quality, and compliance with specifications while identifying potential technical issues before scaling up production.
Samples are often sent to the end customer or engineering team for prototype validation, allowing for mechanical, electrical, or software adjustments. Optimizing during this phase prevents costly errors later. After the sample phase, the project typically progresses to the trial phase and then mass production.
