10. Adjustment of P.C.B. Horizontal Clamping
When a thin P.C.B. is used and the horizontal clamping force is strong,
it may be warped. To avoid this, adjust the force with the pressure re-
ducing valve which is located at the front left (operator side) of the L
conveyor.

• Refer to the following table for the relation between the P.C.B. thick-
ness and air pressure.
The values indicate the pressures to be applied, assuming that a
P.C.B. (Dimensions: "150
100 1.5 (t)") is used without a P.C.B.
stopper.

11. Vacuum Source
• The blower-type vacuum source is provided and used for the vacuum-
type P.C.B. clamping unit and the automatic cleaning (suction type).
(1) Adjustment of Vacuum Suction Force
• The vacuum force can be adjusted with the vacuum control valve.
When the valve is turned clockwise, the suction force weakens.
Turning it counterclockwise strengthens the suction force.

• The vacuum control valve is factory-adjusted to the condition
that it is opened (turned 9 times counterclockwise) from the "Max."
position (fully-closed position).
