Micro-Z Small Dot Pneumatic Controller
The NEW DieMark Micro-Z Small Dot Pneumatic Controller is designed to work with both the Manual and Motorized Micro-Z Inkers along with the NEW A4 Ink Cartrtidge to produce small, 3-5mil ink dots.
The Micro-Z Pneumatic Controller underwent the same evaluation and re-design as the Inker Assemblies in order to maximize small dot performance, and includes the following improvements.
Isolated Shuttle and Cartridge Valve Air Supplies
In previous Pneumatic Controllers, the Shuttle Valve Cartridge Valve shared a single air supply input. In order to eliminate any minor pressure changes that may affect the air input to the Shuttle and Cartridge valves the Micro-Z controller has two (2) regulated air inputs. Each is dedicated to either the Cartridge Valve or the Shuttle Valve to ensure the air supply to each valve and its output is unaffected by the other's operation.
New Digital Cartridge Valve
The Cartridge Valve that supplies air to the ink cartridge to place an ink dot has been replaced with a new digital valve that can be controlled more accurately than the valve used in previous controller models.
New Controller Firmware
The controller has new firmware which controls the "puff pulse" sent to the ink cartridge depending on the position of the toggle switch on the back of the controller. For small dot production using the A4 ink cartridge, place the toggle switch in "A4" position. For other cartridge types, use the "A5-A8" position.
Z-Step and Micro-Z Step
The Motorized Micro-Z inker has a motor driven Z-stage adjustment. When this controller switch is in Z-Step mode the shuttle is adjusted up or down in 0.0005 inch increments with each up or down button press. When in Micro-Z Step mode, the shuttle moves in 0.00005 inch steps up or down with each button press. This allows extremely accurate positioning of the cartridge tip to the wafer surface, which is key to placing uniform, repeatable, small ink dots.
