What is the testing principle of PCBA?
PCBA testing is a key step in ensuring production and delivery quality. It refers to the production of FCT testing fixtures based on customer designed testing points, procedures, and steps, and then placing the PCBA board on the FCT testing rack to complete the testing process. The testing principle of PCBA is to connect the test points on the PCBA board through an FCT test stand, thereby forming a complete path, connecting the computer and programmer, and uploading the MCU program. The MCU program will capture the user's input actions (such as long pressing a switch for 3 seconds), and through computation, control the on/off of nearby circuits (such as flashing LEDs) or drive the motor to rotate. By observing the voltage and current values between test points on the FCT test stand, and verifying whether these input and output actions are consistent with the design, the testing of the entire PCBA board is completed.
