1. Purpose of function
1.1 Background
On small chip parts such as 0603, difference of vacuum level between open and close is
too small to judge parts existence properly. Therefore, parts existence used to be checked
by camera recognition, but it couldn’t find dropped parts after recognition.
1.2 Purpose
This function enables parts existence check by vacuum level from after camera
recognition until before mounting. This will prevent mount failure and misalignment.

2. Function overview
2.1 Outline
Between “after camera recognition of picked parts” and “before mounting”, vacuum level is
monitored for checking of parts existence. It memorizes the highest vacuum level, and
judges “parts fall” if the vacuum level drops below a certain level(※) from the peak.
(※) Specified for each nozzle type in Machine Setting.
2.2 Period of Chip Vacuum Check
Vacuum level is monitored between “after camera recognition of picked parts” and “before
mounting” for all heads(nozzle type) that are set with [Chip Vacuum Check] active and also
picking parts.
