What is a flying probe test?
Flying probe test is a type of board with printed circuits (PCB) or printing district set (PCA), which uses a probe mounted on the mechanical arm. One of the main advantages of using a flying probe test instead of a nail test based on a bed is that the probe can go almost anywhere. In addition to the current testing, the probe also ensures that all parts are there and no one fell. These units can normally integrate with computer -supported design (CAD) programs and are made to work with a limited number of parts, so they usually program them easily.
Flying probes are mostly used in production facilities that create PCB and PCA, although they can be used for other electronics. This test consists of a probe that flies around the unit and uses a needle to test different parts on the unit. In this way, it allows manufacturers to ensure that all units work before they are sent.
Competitors with a flying probe test as the main test standard is a testbed nails. It uses the bed of electronic needles - such as one needle on the probe - to enforce the current through the unit to ensure it works. While the bed method can test a large area at the same time, it is limited to flat units because the bed cannot maneuver angles or curves. The probe can move because it is on the arm, so it can easily check each area of the unit. Two or three probes are usually used to accelerate the workflow.
When ensuring that the unit can properly perform electricity, it is important, there is another matter that is equally important: parts. Some parts may fall during production because they are incorrectly attached or shifted and shook the transition from production. Using the camera and other testing equipment, the flying probe test can also check the correct production.
Flying probes are usually used on conventional APCA PCB and this information will be stored in the probe software. This means that PROblinking the probe to test certain areas is usually easy and small coding is needed. If the unit is unique, most probes can integrate with CAD programs and the user can tell the probe what areas to check from there.
