FCT test – introduction and guidelines
What is FCT test?
FCT test (Functional testing) is the process of ensuring that a product can perform its intended functions and meet user needs. This can be done by testing the PCB board after it has been assembled.
FCT test can also be used to test all components on a PCB board, including PCB resistors and capacitors. If there are any defects in these components, functional testing will help you find them before assembly begins. It involves testing whether all components and interconnections are working correctly, as well as verifying that the design has been manufactured correctly.
This can be done in two ways:
●Using system level test equipment (SLE) to check your design for faults before it goes into production; or
●By using function generators (FGs), which generate waveforms from input signals, and compare these with what you expect to see on your PCB design.
The standards of FCT test
Each electronic component has a set of specifications laid out by the manufacturer. These specifications are used to determine how well the component performs in its intended role. FCT test is carried out to ensure that these specifications are met, often in conjunction with input validation testing.
FCT test can be performed in several ways: bench testing, lab testing, and simulation. Bench testing involves physically running the device under test to check for failure modes. Lab testing involves running the device on a specialized test rig that simulates real-world conditions (e.g., temperature, humidity). Simulation uses software programs to model the behavior of components under various conditions and then compares those models against actual results.
In addition to basic functionality, FCT also tests for proper signal transfer between components as well as proper timing and sequencing of operations. FCT can be done manually or using automated tools such as automated functional tester (AFT). Automated FCT tools are most effective when used in conjunction with manual functional testing.
The difference between ICT test and FCT test
ICT and FCT tests are good methods to check the electronics components but they do have some difference between them as well.
IC test method is a static test method while FCT test is a dynamic test. The ICT gives you an indication of whether your individual components works or not and it works without power, whereas FCT test gives you information about the condition of whole product and it works with power.
The material which ICT test monitors is not completely prepared while FCT test checks the finished products.
The specification of FCT test fixture
FCT test is a method for PCBA testing product that is used to evaluate its reliability, performance, and functionality. It is typically used for software development projects that require high-quality and consistent results.
In order to perform FCT test, the developer must first create a mock environment that simulates the system they are working on. This mock environment may be created using different software versions or hardware configurations. The developer then performs the functional test on the mock environment. The results of the test are then compared to the actual system.
Fixture testing is an alternative method of testing software that can be used when a developer needs to perform multiple tests simultaneously on different systems. Fixture testing can also be performed in production environments where multiple developers are working on the same system at once. Fixture testing can be performed in many different ways including:
1) Simulating real-world scenarios by creating virtual environments.
2) Simulating real-world scenarios by creating virtual machines with custom-built tools.
The FCT test fixture is designed for electrical testing based on the requirement of customer and the test system. It is designed to present the PCB under test at a fixed position using Pogo pins, so that it can be electrically tested. The model BH-16 has been standardized as per IEC 60050-11(Ed2)for
How does FCT test fixture work?
Functional testing is a process of collecting and evaluating the performance of software components. It is a key component in the development process, and it is an essential part of the continuous integration and deployment processes. In order to test a component, it must be able to respond to changes in its environment.
A fixture is an automated way of testing a component that can be used to collect data on how well the component is responding to changes in its environment. There are several different types of fixtures available, including unit tests, and integration tests. Unit tests are the most commonly used tests to check the functionality of a single piece of software.
Integration tests are used for integrating components into larger systems that use different languages or frameworks. Integration tests are useful for testing components that have been created separately for each system type. They are used for testing components that have been integrated with other components in order to ensure that they work together as expected.
What need to be concerned when using FCT test fixture?
One of the most important things to consider when using FCT test is that it should be run on a test-driven development (TDD) approach. This means that you should be testing your code against known entities and structures, rather than new ones. It’s important to remember that FCT doesn’t need to be used for every project; if you’re just testing one or two components.
If you are using FCT test on a large project with many components, it may take longer for them all to run smoothly. This may cause performance issues because different components may not all be able to communicate well with each other due to different architectures and so on.When using FCT testing, it is also important to implement regular tests which should be run against a small set of samples, and not against full production code.
It is essential to note that the testing fixture is not meant for repetitive use. The fixture should be used only once at one time if required. The PCB has to be carefully placed in an appropriate position as per customer’s specifications (including PCB thickness) so that it can be electrically tested by providing Pogo pins through which electrical connections are made with test system being used.

Conclusion
FCT test is a useful technique for testing a PCB board. FCT test helps us to find out the problems in our boards with ease and at a minimal cost. It can save you money by avoiding expensive field trials of your product.
FCT test can be done with a variety of methods, including software simulation and physical tests. In addition to testing the basic functionality of a product, functional testing can also check reliability and safety.
