Electronics & Power Supply Refurbishment
for vacuum coating systems
When a power supply, controller, or vacuum coating electronic assembly has become unreliable, obsolete, unstable, or repeatedly repaired, YTI refurbishes it from the inside out. Our in-house electronics lab rebuilds high-voltage e-beam supplies, DC and RF sputtering power supplies, sweep and emission controls, ion-source electronics, thermal source controls, and legacy process instrumentation so the unit returns clean, calibrated, load-tested, documented, and ready for service.
When repair is not enough
Refurbishment for aging, obsolete, and mission-critical electronics
A single repair can fix a known fault. Refurbishment goes deeper. It is the right path when the unit is aging, drifting, intermittently failing, difficult to calibrate, damaged by heat or contamination, or too important to production to keep running on patched electronics.
YTI evaluates the full assembly, not just the failed part. We inspect boards, connectors, relays, capacitors, cooling components, high-voltage sections, output stages, control loops, interlocks, and instrumentation. Then we rebuild what is worn, repair what is damaged, replace age-sensitive parts, recalibrate the unit, and test it under realistic operating conditions before it returns.
Refurbishment is especially valuable for discontinued and legacy vacuum coating electronics, including power supplies and controls that are no longer supported by the original manufacturer. If the problem is a specific fault only, start with electronics & power supply repair. If the electronics are only one part of a larger coating problem, start with vacuum coating troubleshooting & field service.
Power supplies, controls & instrumentation
Electronics and power supplies we refurbish
From high-voltage deposition power to process controls, YTI refurbishes the electronics that keep vacuum coating systems stable, repeatable, and productive. If your exact unit is not listed, send the make, model, photos, and fault history and we will confirm coverage.
E-Beam High-Voltage Power Supplies
High-voltage and emission control sections refurbished for 270° bent-beam electron-beam sources, single-hearth, multi-hearth, and Ultra Source configurations.
DC & RF Sputtering Power Supplies
Magnetron and diode cathode power supplies rebuilt for stable output, reliable strike, clean control response, and repeatable deposition performance.
Sweep & Emission Controllers
Beam sweep, emission control, rate feedback, and source-control electronics refurbished so the source tracks setpoint and supports uniform films.
Glow-Discharge & Ion Source Supplies
Power and control electronics for plasma cleaning, ion sources, densification, and surface treatment rebuilt for reliable ionization output.
Thermal & Resistance Source Controls
Thermal evaporation and resistance source controls refurbished for stable heating, repeatable output, and dependable process control.
Instrumentation & Process Controls
Vacuum gauging, rate and thickness monitors, valve controllers, relays, interlocks, and process logic repaired, refreshed, and recalibrated.

Signs it is time to refurbish
Problems refurbishment is built to solve
Refurbishment is the best fit when the unit still has value but reliability has started to fall. These are the issues YTI is often called in to correct before they become repeated downtime events.
Repeat Failures
The same unit keeps coming down, or new faults appear after each repair, pointing to aged components or deeper system wear.
Output Drift & Instability
Voltage, current, sweep, emission, rate control, or feedback response drifts out of spec and is difficult to bring back into calibration.
Arcing Under Load
High-voltage supplies, e-beam controls, and source electronics arc, trip, or shut down when real process load is applied.
Obsolete or Unsupported Units
Legacy electronics with discontinued boards, unavailable replacement parts, or no factory support can often be rebuilt or replaced by YTI.
Heat, Contamination & Aging
Dust, heat, process contamination, weak fans, aging capacitors, and brittle wiring are corrected before they trigger the next failure.
Intermittent Board Faults
Hard-to-repeat faults, thermal failures, connection issues, and unstable control behavior traced, repaired, and verified.
What is included
A deeper rebuild than a standard repair
Every refurbishment is scoped around the unit, its age, condition, and role in your process. The goal is to restore dependable performance, not simply clear one alarm.
Disassembly & Cleaning
Internal inspection, cleaning, contamination removal, connector review, wiring checks, and documentation of visible wear or damage.
Aged Component Replacement
Age-sensitive components such as capacitors, relays, fans, wiring, connectors, and weak power-stage parts replaced as needed.
Board-Level Rework
Damaged traces, solder joints, board faults, control circuits, and output-stage problems repaired at the component level.
Calibration & Control Verification
Outputs, setpoints, control loops, sweep behavior, emission response, and interlocks verified and calibrated to support stable operation.
Load Testing & Burn-In
The refurbished unit is tested under realistic load conditions, then verified for stable operation before it ships or goes back online.
Documentation & Warranty
Each refurbishment is documented with findings, corrective work, test results, and recommendations to extend service life.
From unstable to verified
How electronics refurbishment works
Evaluate
Tell us the unit, fault history, process symptoms, and urgency. We review the condition, support status, and whether repair or refurbishment is the better path.
Refurbish
The unit is opened, cleaned, inspected, repaired, and rebuilt. Age-sensitive parts, damaged components, weak connections, cooling issues, and board faults are corrected.
Test & Calibrate
Outputs, setpoints, interlocks, feedback loops, and operating behavior are verified. The unit is load-tested so it is proven before it returns to your chamber.
Document & Support
Every refurbishment is documented and warrantied, with notes on the work completed and recommendations to prevent future downtime.
Depot refurbishment at our Ashford, Connecticut electronics lab is ideal for deep rebuilds, obsolete electronics, and units that need controlled bench testing. For production-critical systems, YTI can also provide on-site troubleshooting and emergency response within 48 hours. See full service details →
