Notes: (1) Both 330 and 380 diameter reels can be mounted on reel holders. The
feeding capacity is a maximum 10,000 parts at 4 mm/pitch and a maximum
5,000 parts at 8 mm/pitch.
(2) A part is fed by a single stroke for a pitch of 2, 4, 8, 12 and 16 mm, and by
multiple strokes for a pitch up to 24 mm.
(24 mm is the maximum length of tape which can be cut off.)
(3) 380 diameter reel holders are manufactured on demand.
(4) The reel's alphanumeric number includes the applicable nozzle size. The
size is the maximum nozzle diameter. Nozzles of smaller diameter can be
used on the feeder as well.
(5) All FCP-6 dedicated feeders are made of aluminum.
(6) The dimensions of the W8, 13-inch parts reel are shown below.
Feeders for the CP6 use a box-type reel holder, providing structural stability
which ensures repeated component pick-up accuracy.

7.1 Camera Unit (Parts Recognition)
The CP642/CP-642(E) is equipped with two cameras, each camera being adapted for
different uses; a high resolution small F.O.V. camera is used to acquire images of small
components such as 1005s and small SOTs, and a large F.O.V. camera is used for SOICs
and PLCCs. Also, frontlighting or backlighting can be selected according to the
configuration of the parts.
(1) Vision Controller
Attached inside the machine's base control box.
(2) Narrow View Camera
Part camera for backlight use
• 1005, 1608, 2125, 3216, SSMin, SMin, etc.
(3) Wide View Camera
The parts cameras can be switched from backlight to frontlight use. Frontlight use
is limited to J-lead parts.
• Backlight compatible parts: 19 x 20 mm maximum
• Frontlight compatible parts: 20 x 20 mm maximum J-lead parts

Notes: (1) Specify the camera type, narrow or wide view, in part data.
(2) If a part larger than 3216 in size is inspected using the narrow view camera, the
placing speed may be reduced. The narrow view camera is intended for inspecting small
components at high resolution.
(3) If a part smaller than 4532 in size is inspected using the wide view camera, the placing
accuracy may be adversely affected. The wide view camera is designed for large components
from 4532 size parts to SQFP 48 pin devices.
7.2 Fiducial Mark Camera
(1) The camera is installed within the head assembly.
(2) The camera is used to accurately locate the board position by inspecting two or
more fiducial marks on the PCB. During operation, corrections are made to the part
placement position using this fiducial mark data.
