1.18 Two Camera System
Because some parts require highly accurate placing, the vision processing system uses
two cameras: a wide view and a narrow view camera.

1.18.2 Wide View Camera and Narrow View Camera
(1) Wide View Camera
The wide view camera has a field of view as described below.
• Using backlighting with an S22 back light disk
The camera can handle a rectangular-shaped part with dimensions of up to 19 mm x
20 mm.
• Using frontlighting with a B22 back light disk
The camera can handle a square-shaped part with dimensions of up to 20 mm x 20
mm.
Generally speaking, the wide view camera can handle parts between size 4532 and SQFP
48 pin. It can also handle parts smaller than 4532 but with reduced placing accuracy.
(2) Narrow View Camera
The field of view for the narrow view camera is up to 9 mm x 9 mm.
This camera can handle parts from as small as 0603 to 3216.
The narrow view camera takes a small part and magnifies the picture so that high
accuracy placement can be carried out.
The narrow view camera can handle parts larger than 3216, but since it computes highly
accurate placing coordinates, vision processing on larger parts takes more time.
0603 (in. 0201) Parts Compatible Camera (Option)
It is possible to mount 0603 (in. 0201) size parts by exchanging the Narrow View Camera
for the optional camera.

Cautions with software
• Use vision software V 2.94 or a later.
• A center measurement cannot be performed using a 0.4 mm nozzle with the Wide
View Camera.
• If a 0.4 mm nozzle is specified as the No. 1 nozzle in the nozzle layout table, a program
transmission error will occur. (Error Code: 11011327).
(3) Data Necessary to Use the 2 Camera System
To make use of the 2 camera system, the following data must be entered into Proper and
Part Data.
Necessary Proper Data
137. Narrow Camera: Use
Set to “Use” when using a NARROW VIEW CAMERA.
Necessary Part Data
To use the wide camera for vision processing, set this entry in vision data to
"Wide_view", and to use the narrow camera set it to "Narrow_view." Use the NARROW
VIEW CAMERA for 3216 or smaller parts.

12. Camera_type: Wide_view Narrow_view
<For F4G>
At the Environment Data’s [Camera] - [Camera Type] item, select either [Wide View] or
[Narrow View].
1. Start the VPD.
2. Open the “Part Type Data” in the relevant part data.
3. Click the [Environment] button to open the Environment Data, then select “CP643” at
the M/C Type item.
4. At the [Camera] - [Camera Type] item, specify whether vision processing is occur
using the WIDE VIEW CAMERA or the NARROW VIEW CAMERA.
Use the NARROW VIEW CAMERA for 3216 or smaller parts.
