Electronics & Power Supply Repair
for vacuum coating systems
When an e-beam supply arcs, a sputtering source won’t strike, or a sweep controller drifts, YTI repairs it — down to the board and component, not just a box swap. Our complete in-house electronics laboratory repairs and recalibrates power supplies, controllers, and instrumentation for virtually any vacuum coating platform, on-site or at our depot, with 40+ years behind every fix.
Board-level repair, not box swaps
Expert repair for vacuum coating electronics & power supplies
The electronics behind a coating process are where a lot of downtime starts — high-voltage e-beam supplies, DC and RF sputtering power, sweep and emission controllers, glow-discharge and ion-source supplies, and the instrumentation that ties it together. YTI’s complete in-house electronics laboratory diagnoses these at the component level and repairs the actual fault, so you get the unit back working and verified rather than a parts-swap guess.
We’ve repaired vacuum coating electronics since 1984 — including legacy and discontinued units that other shops won’t touch, and Polycold and Telemark electronics. Bench repair turns around fast at our Ashford, Connecticut lab, and for production-critical systems our field engineers repair on-site, with nationwide emergency response within 48 hours. Every repair is load-tested and recalibrated before it ships, and backed by a documented warranty.
Repair is one option; a full rebuild is another. When a unit is past economical repair or you want like-new reliability, see electronics & power supply refurbishment. If the symptom is in the coating itself rather than a known-bad box, start with coating troubleshooting & field service, and browse stocked components & replacement parts.
Power supplies, controllers & instrumentation
Electronics & power supplies we repair
From high-voltage deposition power to process controls, YTI repairs the electronics that keep a coating system running. If your unit isn’t listed, send the model — we service virtually any vacuum coating electronics, including legacy hardware.
E-Beam High-Voltage Power Supplies
High-voltage supplies and emission control for 270° bent-beam electron-beam sources — single-hearth, multi-hearth, and Ultra Source guns. Arcing, emission loss, and HV faults repaired.
DC & RF Sputtering Power Supplies
Magnetron and diode cathode drives for RF and DC sputtering — output instability, won’t-strike faults, and matching/control issues diagnosed and corrected.
Sweep & Emission Controllers
Beam-sweep controllers and emission/rate control electronics repaired and re-tuned so the source tracks setpoint and lays down a uniform film.
Glow-Discharge & Ion Source Supplies
Glow-discharge power supplies and ion-source electronics for substrate cleaning, densification, and surface treatment — restored to reliable ionization output.
Thermal & Resistance Source Controls
Power controls for thermal evaporation and resistance sources — repaired for stable, repeatable heating of metals, organics, and dielectric films.
Instrumentation & Process Controls
Vacuum gauging, rate/thickness monitors, valve controllers, and relay/PLC process logic — repaired and recalibrated so your readouts match reality.

In every repair
What our repair process delivers
A YTI repair isn’t finished when the fault clears — it’s finished when the unit is verified to spec and documented. Here’s what’s behind every repair we return.
Component-Level Diagnosis
We trace the fault to the actual failed component, not just the suspect board — so the repair fixes the cause, not the symptom.
Full Load & Function Testing
Repaired units are tested under realistic load on the bench before they ship — no “works on the meter” surprises back at your facility.
Recalibration & Verification
Outputs, setpoints, and control loops verified against spec so the unit performs the way it did when it was new.
On-Site or Depot
Bench repair at our CT electronics lab, or on-site field repair for production-critical systems — emergency response nationwide within 48 hours.
Stocked Parts & Components
Power supplies, controllers, feedthroughs, and supplies in stock — tested, compatible, and ready to ship to keep turnaround short.
Find components →Documented Warranty
Every repair is documented and backed by a clear warranty, with notes on what failed and how to prevent a repeat.
From fault to verified fix
How an electronics repair works
Diagnose
Tell us the unit and the symptom and remote triage starts the same day. On the bench or on-site, we isolate the fault to the component level before any part is replaced.
Repair
We repair the actual fault in our in-house lab using stocked parts, or fabricate a replacement when a board or supply is obsolete.
Test & Calibrate
The unit is run under realistic load and recalibrated to spec, so it’s verified working before it leaves — not after it’s back in your chamber.
Document & Warranty
Every repair is documented and warrantied, with recommendations to prevent the next failure and extend the life of the electronics.
For production-critical systems, on-site repair minimizes downtime and shipping; bench repair at our lab is ideal for deeper faults and obsolete-unit work. We recommend the right path during diagnosis. See full service details →
