On occasion, two boards enter a part placement machine, when only one board should enter the placement machine at one time as shown in Figure 1 on next page. The placement machine will only place parts on the first board, and will ignore the second. The part placement machine does not have the ability to sense the second board entering. Also, with two boards being close together in the part placement machine, sensors throughout the line will not detect the extra board. As a result, the second board will proceed through the rest of the surface mount process without any parts being placed on it.
