6-1-3 Laser Sensor Specifications
The chart below shows the laser sensor specifications for the Coplanarity Checker.
Items Specifications
Lead height detecting accuracy
±5μm
Laser wavelength 650nm
Laser maximum output power 4.8mW
Laser class 3R
Laser measurement range
30±5ｍm
Note: In case that leads are bent horizontally, the Coplanarity Checker may not be able to detect the
bent leads correctly.
Note: The laser sensor works only when the mounter handles the components which Coplanarity
Check function is selected and activated while the mounter is running. When the mounter
pauses, the laser sensor pauses either.
When handling Coplanarity Checker, pay careful attention to it as hereafter.
• Do not soil the surface of laser transmitting/receiving windows with water, oil, or
fingerprints to prevent it from beam refraction. Keep the laser transmitting/receiving
windows away from dirt or dust to prevent it from blocking the beam as well.
• Do not let sunlight or ambient light such as the same wavelength light directly into the
receiving window.
• Do not look at laser beam directly and also do not look at laser reflected by a mirror.

6-1-6 Available Components for the check
Coplanarity Checker can handle QFP, LQFP, TQFP, SOP, SSOP, TSOP, TTSOP, and connectors.
But it is not possible to handle ball components or odd-shaped lead components.
The maximum component size is equal to the specifications of your mounter.
Maximum number of leads: 400 leads
Missing leads: Supported
Thick lead: Not supported
Components that have any wider leads than the others
cannot be checked. (inside the red circles)
Connector’s lead: One side/both sides leads connectors are supported.
(with some limitations)
6-1-7 Pass/Fail Criteria
Pass or Fail is resulted comparing Lead offsets in Z-axis direction (coplanarity) to Assumed
plane of the component.
6-1-8 Restriction for production
The maximum number of Coplanarity Check data for a program;
The maximum number of Image Libraries with Coplanarity Check data for one program is 99
records.
In case of the component like the left drawing,
leads at both sides (inside of red circle) cannot
be checked.

6-2 Data Settings
Note： To enable Coplanarity Check function, it is necessary to select System> User Parameter>
[Coplanarity Check] and check on the [Coplanarity Check] box.
For details, refer to Chapter 11, Parameter Setting.
6-2-1 Procedure to create Coplanarity Check data
Coplanarity Check data consists of several data settings such as Component Shape, Threshold,
etc.
Coplanarity Check data are registered in each Image Library code (SOP/QFP/Connector).
[Steps]
1) Open Image Library window.
2) Do Image Test.
Note: Before creating Coplanarity Check data, pickup offset should be corrected.
Do Image Test before checking coplanarity.
i: Open [Prearrange] window and pick up a component with a nozzle.
Confirm component pickup angle so that it should be as same as when actual production.
And Take care not to have much offset between component center and nozzle center.
For detail operations of [Prearrange] window, see Chapter 5 > Library > Prearrange.
ii: Click [Image Test] and execute component image test.
Repeat [Image Test] until you will get OK in [Result].
iii: The result of Image Test will be used for coplanarity check in the next step. Keep the
component attached to the nozzle and go to the next step hereafter.
3) Open [Coplanarity Check data].
Click [Coplanarity Check data] icon in [Image Library] window. (See the figure below.)
Coplanarity Check data is automatically produced when [Coplanarity Check data] screen” is
opened from an Image Library data. Thus, in order to create new Coplanarity Check data, open
the Image Library data first, and then open the [Coplanarity Check data] screen”.
