Figure 4.12.5.2 Operation flow for performing a coplanarity check
4.12.5.4 Methods for checking coplanarity
The system exercises a series of controls over the vision centering function, and
then coplanarity check according to the settings of Component data, and checks to
see if no error occurs.
4.12.5.5 “Executing coplanarity inspection” dialog box
When you click the <INSP> button on the “Coplanarity inspection” dialog box, the
system executes a coplanarity check function, and the following dialog box appears
while the system is executing a coplanarity check function.

4.12.5.6 Overview of obtaining the coplanarity parameters
The operation flow for obtaining the coplanarity parameters is shown below.
Figure 4.12.5.4 Operation flow for obtaining the coplanarity parameters
4.12.5.7 Methods for obtaining the coplanarity parameters
If the system cannot perform a coplanarity check stably, change the threshold value
of the electrode brightness and the scanning position offset value (applicable for a
lead component only) to obtain the parameters that stabilizes measurement
operation. How any times the system measures a component becomes a multiple
of a value you entered in the “Number of times” field, and may become up to 20
times of the value you entered.

4.12.5.8 “Parameters are under acquisition…” dialog box
When you click the <Acquire> button on the “Coplanarity inspection” dialog box, the
system obtains the coplanarity parameters, and displays the following dialog box
while the system is obtaining the parameters.

4.12.5.9 Dialog box for showing the parameters obtained
When the system obtains the optimal coplanarity parameter, the system displays the
obtained electrode brightness threshold and scanning position offset on the screen.
The parameters set before the system obtains new ones are displayed in
parentheses. When you click the <OK> button, the system updates these
parameters to the obtained ones. When you click the <Cancel> button, the system
maintains the parameters set before obtaining new ones.
