Paper Abstract

Sometimes the objects of isolated surfaces, such as BGA chip leaders, need to be dealt with. Here, a method of visual measurement is proposed for on-line measurement. An image split-splicing technology is developed next to the theory of the system is analyzed to develop the test speed while keeping the resolution. Based on the theory, an isolated surface measurement system is formed for gauging the BGA leaders' top coplanarity.
