3. Conditions for Component Placement
(1)
When components are to
be placed close to the previously-placed
components or the obstacles, the shape of the vacuum nozzle becomes part
of the constraint condition. Refer to "List of Nozzle Types" for the shapes of
vacuum nozzles.
(2)
Adjoining
Distances between Components
(when
the component placement
position is taken into consideration)
F1E11
Note
(a) F1E11 shows that the vacuum nozzles are not protruding from the
outer shapes of components.
When components are placed, any placement deviation may be
caused by solder paste, glue, etc. Here, we don’t take account of
such deviation.
(b) AtoHintheabovegureshowthemaximumdimensionsincluding
the variations in the dimensions of each component. The minimum
adjoining distances (a, b, and c) of each component should be 0.2
mm.
(c) The minimum adjoining placement
position data for component
placement points 1 and 3 is
X Direction Data = + Min. 0.2 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. 0.2 mm
(The
X direction data is not related.)
(e) See F1E11 and obtain the minimum adjoining placement position
data for component placement points 2 and 3.

(3) Limit of Closest Distance to Obstacle
•
The closest distance between
an obstacle (See each sectional view.) and
the vacuum nozzle or component should be 0.5 mm or more.
