12.14.8 Production
The machine runs a coplanarity check during PWB production, trial production and dry run
operation.
A coplanarity check does not inspect a component actually during dry run operation.
12.14.8.1 Procedure for a coplanarity check
① Picking up of a target component
② Moving to a VCS position
③ Recognition of an image of a component with a VCS
④ Moving to the measurement start position of the coplanarity sensor
⑤ Checking to see if the machine can run a coplanarity check for a component
⑥ Position correction according to the result of recognition of an image
⑦ Coplanarity check of a component
⑧ Determination of acceptance of a component based on the result of measurement with the
coplanarity sensor
[Process to be executed after determination of acceptance of a component]
⑧-1 Discarding of a component
⑧-2 Placement of a component on a board
⑧-3 Pause
See the process flowchart
(flowchart of a coplanarity check)

Flowchart of a check with a coplanarity unit
Note 1: Coplanarity check of a BGA or an FBGA is run according to the least-square method
only.
Note 2: The machine does not run a colinearity check for a unidirectional lead connector.
Note 3: A coplanarity check for a unidirectional lead connector is equivalent with a colinearity
check at the present.
BGA?
Run a coplanarity
check
(see Note 1).
Unidirectional lead
connector?
END
END
Run a colinearity
check
(see Note 2).
Yes
Run a coplanarity
check
(see Note 3).

12.14.9 Error handling
If an error occurs while the machine is running a coplanarity check, the error log is displayed on the
screen.
- When you select the <Put into trash box> button (see Section 7.4.4).
- When you select the <Pause> button (see Section 7.4.4).
