38. Conditions for
Component
Placement
(1) Shape of Vacuum Nozzle
When components are to be placed to the previously-placed components or
the obstacles, the shape of the vacuum nozzle becomes part of the
constraint condition. Refer to “8. Vacuum Nozzles of Section 1 ” for the shapes
of vacuum nozzles.

Note: (a) The above figure shows that the vacuum nozzles are not protruding
from the outer shapes of components. Consult our sales personnel
for details.
(b) “A to H” in the above figure show the maximum dimensions including
the variations in the dimensions of each component. The minimum
adjoining distances (a, b, and c) of each component should be 0.4 mm.
(c) The minimum adjoining placement position data for component
placement points 1 and 3 is
“X Direction Data = + Min. 0.4 mm”
(The Y direction data is not related.)
(d) The minimum adjoining placement position data for component
placement points 1 and 2 is
“Y Direction Data = + Min. 0.4 mm”
(The X direction data is not related.)
(e) See the above figure and obtain the minimum adjoining placement
position data for component placement points 2 and 3.

(3) Limit of Closest Distance to Obstacle
The closest distances between an obstacle (See each sectional view.) and
the vacuum nozzle or component shall be 0.5 mm or more. The upper
surface of the P.C.B. is the reference plane.
