Using various functions
6.1 PCB badmark and block badmark
PCB badmarks and block badmarks are specified for the PCB data and
registered in the PCB information.
• PCB badmark
A PCB badmark is affixed on a PCB and used to determine whether or
not the machine searches for block badmarks on the PCB. For example,
when a multi-block PCB with no faulty blocks (no block badmarks) is
fed to the machine, it is a loss of time to search for block badmarks on
that PCB. The PCB badmark function permits the machine to search for
block badmarks only when the PCB badmark is detected. If no PCB
badmark is detected, the machine mounts components on all blocks of
the PCB without searching for block badmarks. (See the operation flow
in 6.1.1.)
• Block badmark
A block bad mark is affixed to each block which is defective. The
machine mounts components only on blocks with no badmark affixed.
For example, if Block B is defective in a multi-block PCB consisting of
4 blocks (A, B, C and D), affix a block badmark on Block B so that the
block badmark function allows the machine to skip mounting on Block
B. Components will be mounted only on Blocks A, C and D. (See the
operation flow in 6.1.1.)
c
CAUTION
The block badmark function can only be used for the PCB data which are registered in
the Blk Repeat Info. (multi-block PCB data using the block repeat function).

6.1.2 Registering the badmark information
c
Caution
The following procedures for setting badmark functions are explained, assuming that
you already have the complete PCB data needed for component mount. If you are not
yet finished with creating the PCB data, complete the PCB data first (see Chapter 5).
1 Register the badmark data.
Open the Mark Info. screen of the PCB data for which you want to use the
badmark function and register the badmark data. For detailed information,
see “6.3 Creating the badmark information” in this chapter.)
2 Open the PCB Info. screen and set the local fiducial and
block fiducial functions..
Set the “PCB Fiducial” and “BLOCK Fiducial” parameters on the “PCB
Info.” screen as follows.
Mark : Enter the badmark data No. you have
registered in the mark on the Mark Info.
screen.
X1, Y1 : Enter the XY coordinates of the badmark in
millimeters relative to the PCB origin (for the
PCB badmark) or the block repeat No. 1 (for
the BLOCK badmark).
Skip : Set to “Exec”.
