MDC E-VAP programmable sweep control

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.
