Function Test

POE can provide you with the functional test (FCT) of the circuit board. Functional testing can ensure that the received PCB components are in working condition.

The purpose of the functional test is to catch the poorly assembled PCBA board. Through the full function test of the simulated circuit board when it is installed into the whole machine, it can find out all the PCB assembly boards that may be defective before being assembled into the whole machine, so as to avoid assembly. After the whole machine was found to be defective, it had to be dismantled and reorganized to cause waste of working hours and loss of materials.

The appearance of this kind of functional testing machine may vary with the size and shape of the product. In addition, the way of functional testing can also vary depending on the urgency of time, the number of test boards, and the cost.

What is functional testing? What are its benefits?

Functional testing (FCT) is the process of checking the function and electrical performance of the PCB. This is usually the last step of testing done before the PCB assembly is delivered to the customer.
In functional testing, the function of the entire PCB assembly is tested instead of individual components. Some of the main advantages of functional testing are as follows:

1. In the functional test method, simulate the working environment of the DUT. By eliminating the need to purchase actual test equipment, this helps customers save significant costs.

2. In some cases, functional testing eliminates the need to perform expensive system testing. This helps save financial resources and time.

3. Functional testing helps to improve the quality of the final product, making it error-free and reliable.

4. With this test method, 50% to 100% of the products can be tested. This reduces the workload and time required for OEM testing and debugging.
