The ICT tester and FCT tester automatically produced by Shenzhen Qianbaishun Technology Co., Ltd. are both DIP segment test equipment. They are often used together when assembling lines for electronic factories. They are both an indispensable part of the process. However, for those who do not understand the principles of ICT testers and FCT testers, they are not very clear about the difference between the two. This article will focus on the operating principles and functions of ICT testers and FCT testers today.
ICT tester is a relatively simple simulation of PCBA, mainly used to check component failures and welding failures. It is carried out in the next process of board welding. The problematic boards (such as reverse welding of components, short circuits, etc.) are directly repaired on the welding line;
FCT is an electronic and electrical functional test, that is, after completing the ict test steps, turn to the product power-on state to test the parameters of the product during normal operation. The advantage of this is that you don't have to pick up and put the product again.
The difference is that the ict tester mainly detects whether the circuit board components are inserted incorrectly and whether the component parameters are normal, while the fct mainly detects whether the circuit board functions normally.
ICT tester, or automatic online tester, is a must-have test equipment for PCBA (Printed- Circuit Board Assembly) production in modern electronic enterprises. ICT has a wide range of applications, high measurement accuracy, and clear indication of detected problems. Even workers with average electronic technical skills can easily handle problematic PCBAs.
FCT (Functional Test) refers to a test method that provides a simulated operating environment (excitation and load) to the test target board (UUT: Unit Under Test) to make it work in various design states, thereby obtaining parameters of each state to verify the function of the UUT. Simply put, it is to load the UUT with appropriate excitation and measure whether the output response meets the requirements. It generally refers to the functional test of PCBA.
ICT tester is a relatively simple analog (resistance, capacitance, inductance, open circuit, short circuit, MAX output, etc.)/digital circuit test (buffer, programming, boundary scan E.G.) for PCBA, using the test machine's own software interface test
FCT is an electronic and electrical functional test of PCBA/products, and the software used is generally based on C CVI labview, etc.
The ICT tester is a machine that tests the resistance, capacity, inductance, on-off and other parameters of each component on the product when the product is not powered on.
FCT is an integration of the ict tester and the functional test, that is, after completing the ICT test steps, it switches to the product power-on state to test the parameters of the product when it is working normally. The advantage of this is that you don't have to pick up and put the product again.
