4.4.4 PWB parameter limits
4.4.4.1 Not allowed dispensing area of the top surface
Figure 1 Top surface of PWB (shape reference specification)
Note 1: In the case where the auto PWB width aligning function (option) is provided, the
minimum length is 50 mm.
Figure 2 Top surface of PWB (pin reference (option) specification)
Note 1: In the case where the auto PWB width aligning function (option) is provided, the
minimum length is 50 mm.
Note : Dimensions at delivery from the factory. The reference pin position in the transporting
direction can be changed on the user side for all the PWB length.

4.4.4.2 Bottom surface of PWB
Figure 3 Bottom surface of PWB
（Hatched portion: support pin non-installable range）
* Note: When the PWB conveyor direction is the rear reference side, direction is symmetrically
up and down to the above figure.
4.4.4.3 Allowable component height & back surface handling height
Figure 4 Allowable component height & back surface handling height
4.4.5 PWB transport reference
Front reference and rear reference (factory setting)
4.4.6 Allowable value of PWB warp
0.2 mm or less per 50 mm and 1 mm or less for both upper warp and lower warp (conforming to
JIS B 8461)
4.4.7 PWB clamping method
The front end and rear end of PWB are clamped on the conveyor rail on the fixed side
and moving side on a basis of the top surface of PWB.
4.4.8 Background transporting function
The background transporting function permits executing the transport idle mode in the
head or X-Y servo-free status or in the unfinished status of home-return.
4.4.9 PWB width alignment method
Standard: Manual alignment method using a crank handle
Option: Auto alignment method using motors
4.4.10 PWB buffer
One PWB buffer is provided on each of the loading side and unloading side.

4.5 PWB Positioning
4.5.1 PWB positioning reference
Standard: Shape reference
Option: Pin reference
4.5.2 PWB recognition visual field
6.3 mm (camera visual field range)
Figure 5 PWB recognition visual field
4.5.3 Window size
The window size is variable up to 6.3 mm. However, secure a clearance around the recognition
mark.
4.5.4 Recognition mark correction method
The reference marks provided at 2 or 3 positions (Note) are used for positional correction of the
whole PWB. When the marks at 2 positions are detected, the position offset, angle offset, and
PWB expansion/contraction of the whole PWB are corrected. When the 3 marks at 3 positions are
detected, the PWB XY angle offset is additionally corrected.
Note: The positions are optional. Regarding the reference marks at 3 positions, however, these 3
marks must not be aligned on a single straight line. (It is recommended that marks are arranged
at the 4 corners of PWB.)
