Overview
Embedded System Testing is a specialized reliability verification process for PCBA boards equipped with embedded systems, firmware, or programmable chips, executed after the basic FCT test is completed. It focuses on verifying the stable operation of the software and hardware integration of the product, the execution capability of the embedded system, and the compatibility of the system with peripheral hardware and software. This process ensures that the embedded system can fully execute the designed functions in the actual operating environment, without crashes, data loss, or communication failures. All Embedded System Testing operations are formulated according to the customer's embedded system specifications and industry general standards.
