Features for Precision

• Solder paste printing is the most important process in SMT
• Go Printers bring on highly precise print
• Designed for accurate and repeatable printing
• For any electronic application while maintaining low investment costs

Camera Guided Stencil to Pad Alignment

• Dual LCD display mounted on the top of the upper frame provides a view of the solder pads on the PCB
• LED illuminates the target area for a crystal clear view through the stencil apertures
• A laser source attached to each camera speeds up navigation and camera positioning during setup
• This feature is especially helpful when locating specific stencil apertures to be used as alignment targets on densely populated electronic assemblies

Robust Synchronized Table Separation

• Slow motion results in perfect shape
• Programmable separation speed matches thixotropy of any solder paste
• Robust design minimizes stencil vibration
• Pure mechanical synchronization for strictly parallel motion of the table
• Outstanding print quality, edge definition, and homogeneous solder paste distribution

Process Control Features

• Full range of adjustable parameters assure repeatibility of results
• Go series provides a level of touchscreen programmability and parameter control uncommon in benchtop SMT stencil printers

Intuitive Touchscreen Interface

• PLC controller allows password-protected programming
• Wide range of parameter settings can be stored as files for various applications
• Programmable settings include print speed, print head front and rear stroke positions, snap-off speed, snap-off distance, PCB thickness, and a correction factor that compensates for stretch as the stencil begins to wear
• The software includes both an automatic mode and a manual/setup mode
• Step-by-step control of each segment of a print cycle, as well as a counter that keeps track of processed boards
• Storage and retrieval of up to 100 programs

Seperation Speed and Distance

• Succesfull snap-off depends on solder paste thixotropy
• Solder paste thickness and dynamics of separation movement
• Slow speed for precise separation is programmable as well as the necessary distance
• The separation accellerates to minimize PCB removal time

Squeegee Pressure

• Squeegee pressure is manually adjustable according to gauge
• Test print to prove correct setup is always recommended

Print Speed and Stroke

• Programmable print speed is a key parameter dependent on specific solder paste reology
• Optimal print speed assures correct paste deposition volume
• Programmable print stroke saves time and solder paste especially during quick product changeovers

Flexibility

• Go printers come complete with a full supply of magnetic PCB mounting hardware
• Wide range of squeegees available
• Quick and simple frame size adjustment and wide angle opening
