PWB transportation specifications
L/L-Wide -PWB specification : Front fixed or Rear fixed (factory set)
XL -PWB specification : Front fixed only (factory set)
PWBs clamping method
This is a method to use the PWB top surface as a reference to have both the PWB front and
rear ends each at the fixed and movable sides supported to the carryout rails, then, to clamp
the PWBs.
PWB width adjusting methods
Automatic PWB width adjusting method via a motor
(Minimum board size: 50.0 mm × 50.0 mm)
PWB buffer
The conveyor section consist of "three buffers +two stations” which are <IN buffer>, <IN
buffer>, <IN station >, <JOINT buffer>, <OUT station> and <OUT buffer>.
The buffers are limited according to the "X-direction size" of a PWB.

4-7-6 Function correcting the PWB positions
Field of vision for recognizing the reference marks
□6.3 mm (camera’s field of vision for recognition).
Window size for recognizing the reference marks
This size can be adjusted within the maximum 6.3 mm-area, subject to securing a clearance
between the recognition mark and its surrounding area.
Kinds of recognition marks and corrective method
- PWB reference mark
Two or three marks are located on a PWB to correct the entire PWB.
When a machine detects two PWB reference marks, it corrects the positioning, angle and
expansion/contraction of the entire PWB. When detecting three PWB reference marks,
it corrects the perpendicularity in the X and Y direction also.
- Marks used to position the component area
Two marks (their positions can be set as you like) are to be provided to a group of
components placement positions, and they are used to correct each component
placement position in the group (Up to 50 sets of marks).
Note 1: The position is arbitrary, subject to not aligning three (3) reference makes,
if this is the case, on one (1) straight line. (It is recommended that the reference
marks should be made at the four (4) corners of the PWBs
Note 2: PWB reference marks in two or three positions (four or six positions in total), which
can be detected every time when the PWB is fed, are necessary by split clamping
PWB transport that is an option to a longer sized PWB in X axis.

Basic quality of recognition marks
- Copper not coated or coated
- It needs to have a clear contrast between the recognition mark surface and the print
wiring quality.
- It needs to have neither oxidation nor quality deterioration of the recognition marks.
Coating the recognition marks
The recognition mark surfaces shall all be coated as follows:
- Transparent antioxidant coating - Nickel plating
- Tin plating - Gold plating
- Hot-air levelling solder coating
Mark shapes to be recognized
- The standard marks represent the thirteen (13) forms as shown in the following block,
“forms of recognition marks.”
- For any mark other than those shown in the said block, customers shall make templates
to allow for recognition through a pattern matching.
Note 1: Three types of reference marks or up to six types of area marks/component
positioning marks can be supported.
Note 2: Within a field of vision, there should be no similar form pattern other than the
subjected form patterns.
- For regular triangles, checker patterns and users’ templates, the 90°up-side-down
marks can also be recognized.
