(12) Placement range every clamping
Enter a placement range at first clamp when clamping a large-shape PWB whose
PWB external size X exceeds 650 mm. When the number of components to be
placed is small, the tact may be improved by changing the placement range every
clamping.
[Three components can be picked up at once.]
Adjusting the placement range every clamping will reduce the pickup count from 5 to
4. This greatly improves the tact.
* For using a large-shaped PWB whose external length X exceeds 1200mm
(option):
If the placement range at first clamp is changed from 650 (mm), a PWB range that
cannot be placed may occur. So, do not change this placement range.
Placement range at first clamp: 650 mm (initial value)

4.1.2.2.3 Dimension settings (multi-circuit PWB)
When a PWB in which multiple same circuits are arranged on a single PWB is called
“multi-circuit PWB.” As placement data, create the data for a single circuit (this circuit is
called “reference circuit”) and enter the circuit arrangement information (inter-circuit pitch,
number of circuits, etc.) into the PWB data.
Two types of multi-plane PWBs are available: matrix circuit board and non-matrix circuit

(1) Multi-plane matrix PWB
This is a PWB on which all circuits have the same orientation and the distance (pitch)
between circuits is equal.
Select the reference circuit (select a circuit at the left bottom, in general) among
circuits on a PWB.
Then, set the PWB origin and the circuit origin for placing the reference circuit and
enter the information of the number of circuits and the pitch between circuits.
By these data entries, the system places the specified number of circuits on a board
with based on the placement data of the reference circuit that is created on the
“Placement” data screen with shifting the position of each circuit by the specified
pitch.
