A. Standard analog switch/button/dial controls.
B. Heavy duty base frame keeps machine vibration free at all speeds.
C. Aluminum print table with honeycomb construction and vacuum hole size 1.5 mm with pitch 20x20mm. Optional custom vacuum hole size is 1 mm with pitch 14x14mm and a center hole in-between four holes to ensure that substrate has higher surface contact with print table throughout printing cycle. Recommended for thin films / substrates.
D. Heat dissipating turbine vacuum offers powerful suction and blowback. Vacuum and blowback micrometers are independently controlled and numbered for repeatability. Blowback function allows substrate lift when gripper holds the leading edge of substrate to avoid scratching when print table returns to operator.
E. German SEW-Eurodrive motor powers four-post head lift on linear bearings and guide rails. Includes synchronized transmission shaft, double chain, encoders and photo sensors to control screen up / down position.
F. Variable gripper release to synchronize with print table return includes dwell timer to ensure level drop off onto conveyor belt.
G. Mechanical peel-off and off-contact is built into 4-post design.
H. DC driven squeegee and flood travel on precision linear bearings and cog toothed belt.
I. Utilizes special ball bearing micrometer design instead of thread bolt type adjustment. This is designed to prevent stripping out and offers play-free registration without backlash during setup.
J. Print table X / Y movements adjusted via precision scaled micrometer controls for fine registration with numbered value for repeatability and standardization.
K. Print table motion cycle driven by top-class servo motor, using swivel arm system guided by linear rail for consistent repeatability.
L. Pneumatic frame locking system with check valves / airlock and four-sided frame holding assembly ensures rigidity and high stability.
M. Pneumatically controlled squeegee and flood coater equalization allows precise pressure and ensures even ink deposit. Adjustments include numbered fine-tuning depth, skew-angle (snowplow feature), and swivel-angle of squeegee and flood coater.
N. No-peel flood coater function.
O. Squeegee / flood high-park capability facilitates faster setup and changeover.
P. Choice of flooding before the print stroke, flooding after the print stroke, or higher cycle speed-flood while screen lifts to full up position.
Q. Select the number of print cycles necessary for printing job and the machine will stop running automatically upon completion of the set amount.
R. The control system for compressed air supply is an oil free FRL unit to prevent oil mist pollution, particularly applicable in clean room environments.
S. To protect operator two safety bars are located in front of the sliding table. When safety bars are in the open position, the table cannot return back to home position until they are closed off. Meets and exceeds all European and US Safety requirements.
Options:
Dripless squeegee system (rotary type), Cleaning roller, Anti-static bar, Registration pins, Optic sensors for substrate alignment, and Custom vacuum hole size 1.0 mm with a pitch of 14x14mm and a center hole in-between four holes to ensure that substrate has higher surface contact with print table throughout printing cycle, and ideal for thin films/substrates.
