Abstract:
A mounting system for mounting an electronic part on a mounting body by aligning leads of said electronic part with corresponding bonding terminals of said mounting body, said leads being arranged on four sides of said electronic part, said system comprising:positional-data forming means for forming positional data of said leads and said bonding terminals;line arithmetic means for calculating, from said positional-data, lead lines representing rows of said leads of said electronic part and bonding lines corresponding to said lead lines and representing rows of said bonding terminals;base-point/base-line arithmetic means for calculating base points and base lines of said electronic part and of said mounting body, said base lines being calculated as diagonal lines of a rectangle defined by said four sides, and said base point being calculated as an intersection point between said diagonal lines of said rectangle;position/angle arithmetic means for calculating positional-interrelationship between base points of said electronic part and said mounting body and intersection angles between the base lines of said electronic part and said mounting body; andposition/angle control means for controlling interrelationship in position and angle between said electronic part and said mounting body based on said positional interrelationship and said intersection angles.
