5.2.9. MNVC (Factory-Set Option)
This is an optional function that uses a VCS to recognize a component that is picked up by
an LNC60 head, and you can use the MNVC to perform various operations such as a
coplanarity check and recognition of a general-purpose vision component.
Use of the MNVC greatly improves the productivity of a PWB on which many small
vision-centered components are to be placed.

Note 1: Any L head cannot be used to recognize a component by dividing its image.
Note 2: The component height, lead pitch, ball pitch and ball diameter that can be recognized by the
L head are same as those that can be recognized by the R head.
Applicable nozzles
− Standard nozzles: The number. 500 to 508C nozzles are applicable. Be sure that the
number. 505, 506, 507 and 508C nozzles shall be antidazzle.
− Customized nozzles: The section of any customized nozzle that is used to pick up a
component should not gleam when it is shot with a VCS except the area ± 2.0 mm from
the center of the nozzle.
The diameter of this gleaming area should be 4 mm or smaller.
This area should not gleam.
The width should be 4 mm or narrower.

5.2.10. High resolution camera (Factory-Set Option)
When a line unit that permits switching between reflection and transmission recognition and
switching among wavelengths (red, blue, and green) is combined, fine-pitch components
(leads and balls) that cannot be recognized by standard camera can be recognized.

5.2.11. Coplanarity (Factory-Set Option)
By moving a target component that is to be measured at constant speed in the direction
(Y-direction) perpendicular to the laser line (X-direction), the camera shoots the diffuse
reflection of laser beam emitted to the component and the device creates 3-D image to
measure displacement without touching the component. This device determines if a
component is appropriate or not based on the 3-D image obtained from the component
information sent by the mounter in advance (that is, checks the height of the electrode).
Colinearity check:
The colinearity check inspects “how much a side on which leads are located is bent in the
up/down directions.”
Coplanarity check:
This check can check coplanarity (uniformity of the bottom of a terminal) of a component with
the three-point method (JEDEC standard: JESD22-B108A) or the method of least squares
(JEDEC standard: JESD22-B108A).
Applicable components
- Components to be recognized with a VCS only.
- BGA, FBGA, connector, and lead components (SOP and QFP) whose respective pitch
is the same and whose respective lead width is the same
-
*1. If you do not enter the correct lead width and electrode size of a component whose
lead width is less than 0.3 mm on the “Component” data screen of the Program Editor,
the system may not be able to detect its terminal correctly.
◆Component height 12.0mm or less (HC spec.：20.0mm、EC spec.：25.0mm）
A product whose laser class is 3b is used in the coplanarity sensor.
- Key switch
The front section of the machine is equipped with a key switch. Only when the key
switch is set to ON, you can use the coplanarity function.
- Cover open
Regardless of the key switch state, any laser is not emitted when the cover opens.
