Case Solution
If component is not placed on land
without APC correction
Check placement coordinate and parameters.
Specified component has a certain
amount of misalignment
Check if coordinates and relative positions of the placement
coordinate data and the gerber data for mask solder printing are
correct, and also check that the data is matched to the data actually
used for production.
●When both data sets are merged by DGS, the relative relation
between the placement coordinate and solder position is recorded,
and the correction position is calculated based on that data.
If a flat offset is applied to all PCBs
Check if the PCB recognition coordinate is correct. Also, check that
the relative position is correctly matched (the center coordinate of
two solder centers for a chip component should be matched to the
placement coordinate of the component) when the placement
coordinate data and the gerber data are merged by DGS.

If a placement position is misaligned before reflow
1)
1) The design value shall be used for the placement coordinate data and PCB recognition coordinate data.
After data creation, if the data of the placement coordinate is edited based on the actual component, APC
correction may not perform properly.
The production method by using the APC system corrects the data to produce conforming PCBs with
considering influence on solder misalignment caused by PCB and mask deformation, and other factors.
Because component variation is correctly measured, the design value must be used for the placement
coordinate data and the PCB recognition coordinate data.

Number of placement points: Max. 10 000 points /machine
(Placement coordinates, recognition mark coordinates, bad
mark coordinates and PCB height measurement points are
included.)
* In the case of production in dual lane mode, it is the total
number of placement points in the front and rear lanes. In
the case where the number of placement points is more
than 10 000points/line, please consult with us separately.
Also, about the line mixed with the CM/DT series, please
consult with us separately.
