What is the difference between the ICT tester and the FCT test?

ICT tester test fixture and fct test fixture are both a classification of test fixtures. Different test fixtures have different test functions. What are the functions of ICT and FCT test? What is the difference? The following is a small series for everyone to explain. .

First, ICT test fixture:

1. Can quickly check out the assembled circuit board (PCB) on the device, whether it is within our design range.

2, can quickly find the location of poor soldering, such as missing parts, wrong parts, open short circuit, reverse, continuous welding and other issues.

3, can print out the above faults and bad specific information for the reference of maintenance personnel, effectively reduce the dependence of maintenance personnel on technology, do not need to understand the product schematic, still have the ability to maintain.

ICT is mainly suitable for:

1, into a batch of boards (cause: each type of board needs to have a corresponding fixture);

2. A board with a high added value and a fixed value;

FCT is a functional test fixture, mainly for testing the function of the product. Its main test object is PCBA circuit board. PCBA needs to test its various performances through different fixtures. The FCT test fixture is mainly for PCBA. Tests after power-on include test items such as voltage, current, power, power factor, frequency, duty cycle, brightness and color, character recognition, voice recognition, temperature measurement, pressure measurement, motion control, FLASH and EEPROM programming. .

The FCT desktop computer function test fixture is a mechanical auxiliary device used to test whether a desktop computer has reached the original designer's purpose by testing a certain process in the semi-finished product/finished product or production process. The functional test fixture is applied. Analog, digital, memory, RF, and power circuits require corresponding functional test fixtures for each form.

What is the difference between ICT tester and FCT test fixture? Summary: ICT test fixture is mainly to test the performance of all aspects of online components. The purpose of the test is to check the defects and some bad components in the production process. The object it tests is semi-finished and the FCT test fixture is mainly for functional testing of the finished PCBA. The FCT fixture is mainly a test method that simulates the working environment of the product and puts the product in working state to detect its various states to verify the function of the target board. Both ICT test fixtures and FCT test fixtures are used in the production line of electronic products.
