close to the board edge.
The adjustable snugger plate, rear rail guide and fixed snugger plates are
interchangeable with similar units to facilitate differences in board thickness.
This system caters for 0.8mm, 1.0mm and 1.6mm board thickness.
To clamp the board in position for the printing process, the board is gripped
between the fixed and adjustable snugger plates by action of the pneumatically
operated piston. Pneumatic operation utilizes the existing board clamp circuit,
(via a 24V switched solenoid 16SOL10 from the machine controller).
On completion of the print stroke the pneumatic solenoid is de-activated allow-
ing the actuator pistons (sprung loaded), to retract the adjustable snugger plate
away from the board.

Foil-less Clamps This option is used on thin boards which are populated with components too
close to the edge of the board for traditional board clamps. The board is
secured during the print stroke by the use of vacuum. The clamps are
perpendicular to the board maintaining a good gasket between the board and
