<p><P>PROBLEM TO BE SOLVED: To find a contamination in the early stages to avoid an unnecessary follow-on mounting of electronic components. <P>SOLUTION: When an abnormal drop of an electronic component is determined by a CPU (central processing unit) in a step of sequentially mounting the electronic components on a printed circuit board (S5), an inspection for the existence of the contamination is conducted at the mounting point before and after the occurrence of the abnormal conditions (S6). When the CPU determines the abnormal conditions (S8) to control to stop the mounting operation of the electronic component of an electronic component mounting device, visually and aurally notifying the existence of the contamination on the printed circuit board by a notifying means (S9). <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
