Product Description
MDC E-VAP Programmable Sweep Control (Vacuum Deposition System Controller)
This is an MDC E-VAP programmable sweep controller, a specialized instrument used to automate and control sweeping or rotating substrates in vacuum deposition systems (e.g., thermal evaporation, e-beam evaporation). Designed for precise thin-film coating uniformity, this controller is sold AS IS for parts, repair, or integration into a compatible vacuum coating setup.
Key Features (Based on MDC E-VAP Series):
-
Function: Controls the speed and pattern of rotary feedthroughs, planetary rotators, or substrate sweeps inside a vacuum chamber
-
Programming: Likely features programmable sweep profiles, speed ramping, and dwell times for complex coating sequences
-
Display/Interface: Digital readout with keypad or dial controls
-
Output: Drives DC or stepper motors via compatible feedthroughs
-
Connectivity: May include RS-232, analog I/O, or relay contacts for system integration
-
Applications: Thin-film deposition for optics, semiconductors, research coatings, and decorative finishes
Potential Uses:
-
Vacuum System Repair: Donor unit for restoring an identical MDC-controlled evaporation or sputtering system.
-
Component Salvage: Stepper motor drivers, power supply, display, precision potentiometers, and connectors.
-
Custom Coating Projects: Repurpose for DIY thin-film deposition, planetary rotation control, or automated substrate manipulation.
-
Educational Display: Example of industrial vacuum process control for engineering or materials science programs.
Important Notes:
-
Compatibility Required: This controller is only functional with matching MDC (or compatible) rotary feedthroughs and motors.
-
Configuration Unknown: Programming, calibration, and communication settings are not provided.
-
Technical Expertise Needed: Suitable for vacuum engineers, coating technicians, or experienced hobbyists.
