Visual Inspection
PCB Visual Inspection or manual test is a type of testing method that involves human interaction in the testing process. It is usually carried out by experienced technicians who visually inspect and test the PCB boards for defects and errors. The manual test is usually carried out in the early stages of the production process, and it helps to detect any faults that might have been missed during the automated PCB testing process.
Visual Inspection involves using various tools, such as a multimeter, oscilloscope, and other testing equipment, to check the functionality of the board. This testing method is time-consuming and can be expensive, especially for large-scale production runs. However, it is necessary to ensure that the PCB board is fully functional and meets the required standards.
PCB Visual Inspection can also be used to test the functionality of the finished product. For example, if the product is a complex electronic device, a technician can test it by powering it on and checking all the functionalities of the various components. This process helps to ensure that the product meets the required specifications and functions as intended.
