MACHINE PERFORMANCE
Carry out a machine capability check and compare the results with the check
completed prior to transportation.
Machine Capability Load the product file named 265test1 from the hard disk and with a DEK
alignment board loaded ensure that the following parameters are correct:
• Screen - Calibration/Dry Align
• Squeegee - Length to suit board / ProFlow - Empty Transfer Head
• Front & Rear Print Speed - 25mm/sec (squeegees) / 70mm/sec (ProFlow)
• Front & Rear Pressure - 5kg (squeegees) / 3kg (ProFlow)
• ProFlow Paste Pressure - 2.0 bar
• ProFlow Idle Pressure - 0.2 bar (ProFlow with SCAR)
• Separation Speed - 1mm/sec.
• Under Board Clearance - 20mm
• Paste Dispense - 0
• Under Screen Rate - 0
• Transport Mode - Left to Left
• SPC Data Output Rate - Every Cycle
• SPC Data Mode - Disk
• SPC Format - Windows
• SPC Align Inspect Mode - Pre & Post Print
Use nine magnetic tooling pins to fully support the board, apply a small amount
of paste or suitable lubricant (enough to lubricate squeegees). Record >100 full
machine cycles and setup QC-Cal program as follows:
1. Start the QC-Cal program.
2. Select Statistics, Cpk - Process Capability.
