What is Functional Testing? What are its Benefits?
Functional Testing is the type of testing done against the business requirements of application. It is a black box type of testing and Function testing (FCT) is the process in which the functioning and the electrical performance of the PCB is checked. It is typically the last step testing done before the PCB assembly is shipped to the customer. In this type of testing, the functioning of the entire PCB assembly is tested rather than individual components. Some of the key benefits of functional testing are as follows:
In functional testing method, the operating environment of the DUT is simulated. This helps a customer save a considerable cost by eliminating the need to buy actual testing equipment.
In some cases, functional testing eliminates the need of performing system tests that can be expensive. This helps save on financial resources, as well as time.
Functional testing helps improve the quality of the final product by making it error-free and robust.
With this method of testing, one can test 50% to 100% of the product being shipped. This cuts down the efforts and time required for an OEM to test and debug it.
Each type of testing has its own pros and cons. Therefore, it is hard to say which type is superior to the other. It entirely depends on the application. You can ask an expert to suggest you the best testing procedure for your requirements. One such expert whom you can consult is MOKO Technology Ltd, which has a wide experience in custom PCB design and assembly.
