Introduction of MVI & ICT & X-Ray Inspection

MVI (Manual visual inspection):Manual visual inspection, shortly as MVI, is a method to detect defects in digital circuits by naked eye, magnifier and microscope in SMT production. In the manual visual inspection, you can also make a comprehensive judgment with the help of metal needles or bamboo toothpicks, and with appropriate force and speed across the QFP pins. In addition, MVI has a good effect in checking whether the IC pin has pseudo soldering or bridge connection. MVI with the aid of mag...
