5 − 11
Note 1: For a staggered type of BGA (see
⑦
of Section 5.2), the maximum value is 25.
Note 2: The checking precision cannot be guaranteed when you select “ Ceramic”.
Note 3: When you select “PWB” or “Ceramic”, the machine cannot divide and recognize image of a
component. For an FBGA, “PWB” and “Ceramic” do not appear on the pop-up menu.
Note 4: The minimum ball pitch is 0.7 mm for an optional 37-mm VCS, 0.5 mm for an optional
27-mm VCS, and 0.35 mm for an optional 18-mm VCS.
Note 5: The minimum ball diameter is 0.28 mm for an optional 37-mm VCS, 0.2 mm for an optional
27-mm VCS, and 0.14 mm for an optional 18-mm VCS.
Notes:
The machine cannot recognize a component if:
①
the machine does not detect any clear contrast between a solder ball and a
board on which a solder ball is mounted,
②
the machine does not recognize a ball alone because a pattern whose
diameter is the same as that of a solder ball is connected to a solder ball, or
③
there is a through-hole whose diameter is the same as that of a solder ball on
a board on which a solder ball is mounted.

Note: Outline-recognized components
1) Component size (with a reflective light)
- Maximum component size: 50 mm x 50 mm
- Maximum component size recognized with optional VCSs
Optional 37-mm VCS: 34 mm x 34 mm
Optional 27-mm VCS: 24 mm x 24 mm
