1) When part placement is possible but placement accuracy is poor

At least two fiducial marks are required within a placement area,

but if there is only a single fiducial mark within a placement area,

this equipment can use the fiducial mark to calibrate just the X

and Y coordinates, but cannot calibrate the theta coordinates.

Therefore, the two or three-level placement method is not

recommended for IC parts, which require a high level of

accuracy.

 When the array or block fiducial mark is overlapping across

two placement areas

 When there are only two panel fiducial marks

2) When part placement is not possible

 When there is a bad/accept mark or a 2D barcode in the

second placement area

If the bad/accept mark or the 2D barcode cannot be

recognized in the first placement area, you cannot use the

bad/accept mark or the 2D barcode.

 When a part with lower placement priority exists in the first

placement area

You must set the placement level of the parts if there is any

interference with the placed parts nearby depending on the

placement order. When a part with lower placement level

exists in the first placement area, a cycle NG error will occur

and the PCB program cannot be created.

Memo The specifications of the buffer that can be used in the

equipment are as follows.

 <8. Handling> group

Set the data necessary for PCB operation.

 <Move Z>

After the part is picked up, set the head moving height with the surface of the PCB

being “0” when moving the head.

The default value is 4mm. However, if the placed part height is higher than 4mm,

input the height part in mm unit when it is placed on the PCB.
