PCB Functional Test & Programming

PCBA Online Programming:

Before finishing welding, we usually program the microcontroller in the PCBA board to enable the microcontroller to achieve specific functions. PCB testing software will improve efficiency and reduce production costs.

PCBA Test

Including ICT test, FCT test, Burn-In Test, fatigue test

ICT Test (In-Circuit Test)： Through the test probe contacting the test point of the PCBA, the main PCBA test circuit continuity, voltage and current value, fluctuation curve, amplitude, noise, etc.

PCB Functional Test Requirements

Before discussing design, test systems, software, and test methods, it is important to understand the “object” – the PCB product to be tested, not only the PCB or final assembly itself, but also how much will be produced, the expected failures, etc., including

Product type

Structure (single PCB / pre-made PCB / final product)

Test specification plan:

test point expected production (per line / per day / per shift, etc.)

Expected failure type

Obviously, the above ignores the “budget”, but only after understanding the above items to determine how much a product test to spend, to figure out what is needed to PCB functional test the UUT before you start discussing funding issues, and only at this time to know how to make compromises to get the job done.

PCB Functional Test & Programming Quality Control

FCT Test (Functional Test):

Firstly we need to program the prepared single-chip microcomputer (MCU) into the program IC through the burner, this step is conducting a simulation test for all PCBA tests. Then it has any questions from hardware and software, we will also be equipped with the necessary patch processing production tooling and test racks.
