What is the test principle of PCBA?

To guarantee the quality and dependability of the circuit board, PCB assembly testing is a crucial step in the production process. A range of testing techniques are typically employed in PCB Assembly testing to identify the circuit board's numerous performance indicators. The fundamentals of PCB assembly testing as well as popular testing techniques will be covered in this article.

PCBA testing is a key step to ensure the quality of production and delivery. It refers to making FCT test fixtures according to the test points, procedures, and test steps designed by the customer, and then placing the PCBA board on the FCT test rack to complete the test process. The test principle of PCBA is: to connect the test points on the PCBA board through the FCT test rack, thereby forming a complete path, connect the computer and the burner, and upload the MCU program. The MCU program will capture the user's input action (such as long pressing the switch for 3 seconds), after the calculation control the on and off of the side circuit (such as LED flashing) or drive the motor to rotate, etc. By observing the voltage and current values between the test points on the FCT test stand, and verifying that these input and output actions are consistent with the design, the test of the entire PCBA board is completed.

To guarantee the quality and dependability of the circuit board, PCB assembly testing is a crucial step in the production process. To verify that the circuit board's electrical performance, functional performance, and dependability satisfy the necessary standards, several performance indicators can be identified during the PCB Assembly test. The PCB Assembly test helps to guarantee the quality and dependability of the circuit board by identifying and fixing board issues promptly.

To put it briefly, PCB assembly testing is a crucial step in the production of PCB circuit boards that helps guarantee the dependability and quality of the board. A range of test techniques are needed for the PCB Assembly test to identify the circuit board's numerous performance indicators. The PCB Assembly test helps to guarantee the quality and dependability of the circuit board by identifying and fixing board issues promptly.
