PCBA testing is important during PCB assembly process, ICT and FCT is 2 main test methods of PCBA

1. ICT is a relatively simple simulation of PCBA. It is mainly used to check component failures and
soldering failures. It is carried out during the process of board soldering. The problematic board
(such as components wrong direction, short circuit etc.) is directly reworked on the soldering line.
ICT is an automatic online test equipment for PCBA (printed circuit board assembly) production,
which is necessary for modern electronics companies. It was widely used, with high measurement
accuracy, and clear instructions for detected problems. Even workers with low electronic skills can
easily handle problematic PCBA.
FCT is an electronic and electrical functional test, that is, after completing the ICT test steps, it is
switched to the product power-on state to test the parameters of the product under normalworking
environment. The advantage of this is that you can directly see if the production is work or not.
FCT (Functional Test) refers to providing a simulated operating environment to the test target
board (UUT: Unit Under Test) to make it work in various design states, so as to obtain the
parameters of each state to verify the UUT function is good or bad. Simply speaking, it is after
PCBA programmed, load the UUT with appropriate voltage and current, measure whether the
output response is correct. Generally refers to the functional test of PCBA.
The difference is that ICT mainly detects whether the components of the circuit board are installed
correctly, and if the parameter of test points are normal, while FCT mainly detects whether the
function of the circuit board is normal.
