This year, aviation airborne electronics has developed at an alarming speed in the direction of lightness, thinness, shortness, high density and high reliability. The foundation is electronic and microelectronics. Aviation microelectronics assembly technology is to realize the miniaturization of aviation airborne electronic equipment and systems. , An important means of integration, high performance, good high reliability, SMT process production with fine pitch surface mount devices such as QFP, PLCC, BGA, etc., is an important means to improve the quality of aerospace equipment.
