Title: Electronic component mounting method
Inventor: KINO MIKIO
IPC: B23P21/00
Filed: 1988-10-03
Abstract: PURPOSE:To improve the packaging of electronic components in efficiency by a method wherein the components out of a group of electronic components which are mounted on a unit board of a multisurface board, which are easy to deviate positionally or drop off due to their shape after they are attached, are grouped and mounted at a low speed operation after the other components have been mounted in an ordinary mounting sequence. CONSTITUTION:Heavy components are liable to deviate positionally or come off but light components are not. In a multisurface board 10', the same mounting pattern is repeated four times for four unit boards 11, and then the mounting for a board 12 is performed in an original mounting pattern. A mounting sequence is inputted in a data inputting stage. The mounting sequence is changed by a software through a control device 40 so as to mount only lightweight components according to the initially set sequence at a high speed operation skipping over the heavy components, and the mounting of a group of the heavy components is made to start after the lightweight components have been mounted. At this point, a mounting mechanism is driven slower than before so as to prevent the heavy components from deviating positionally or coming off. By this setup, a mounting operation can be efficiently performed according to mounting sequences set for each group, while driving the mounting mechanism at an operational speed adapted for each group.
