11.8 Unmountable areas on board
As illustrated below, the board includes areas where no components can be mounted due to the interference
with the conveyor rail, particularly with the board clamp claws.
Additionally, 30mm-straight zones expressed by "A" to "D" are required for the board edge to halt against
the stopper. The stopper is installed at a position of "A" to "D" depending on the machine configuration
determined by the conveyor type, board transport direction, and conveyor reference.

11.9 Applicable board thickness
0.4 to 3.0mm
11.10 Applicable board weight
0.65kg or less per sheet
* Consult us for board weights exceeding 0.65kg.
11.11 Recommended board material
Glass fiber reinforced epoxy resin
* Consult us for other materials.
11.12 Allowable board warp
0.5mm
1.0mm
Upward warp: 0.5mm or less
Downward warp: 1.0mm or less
* Warps which exceed the above values (particularly the upward warp) may significantly reduce the
component mounting accuracy. An excessive warp may cause interference with the head, nozzle,
or camera, so use caution.
11.13 Board slits and holes
The conveyor is equipped with sensors (light transmission type) to check the position of boards being
conveyed. The position of the boards may not be detected correctly if they have slits and holes.
Consult us when using such boards.
