4.6. Component Placement Accuracy at X, Y and θ
*1 The regulated value of a component to be recognized with laser is “Cpk ≥ 1.”
*2 The placement accuracy that can be obtained when a placement position is corrected by
recognizing component image shall be the absolute value from the component reference
mark or PWB reference mark.
*3 The placement accuracy of a 0402 component described below is realized if local fiducial
marks are used, the distance between two marks is 20 mm or less, and a 0402
component is placed within the mark.

4.7. Applicable PWBs
4.7.1. PWBs transport direction
Rightward flow (transporting from left to right, looking from the front side)
Leftward flow (transporting from right to left, looking from the front side)
Note
：
This direction is set at the factory (Factory-set).

Note 1: “L” indicates the dimension in the board transport direction, and “W” indicates the direction
perpendicular with “L.” W/L should be 2 or less.
Note 2: Contact us for a notched board or board whose shape is irregular.
Note 3: A PWB whose reflection ratio is low may not be able to be detected regardless of its material
or color.
2) Maximum allowance of PWB mass :2,000 g
3) Allowable warpage of a PWB
0.2 mm or less per 50 mm area, and 1 mm or less for both upper and lower directions
(these values conform to the JIS B 8461 regulation.)

4.7.3. Unavailable areas for placing components on the board
Note 1: This is a size at shipments from the factory. Another restricted area is added when centering pin
(option) is used.
Note 2: Minimum board size becomes 50 mm when Automatic PWB transportation Width adjustment device is
attached on the machine.)
