Technology & Applications Pages
In this section, you will find a number of easily understood technical briefs that have been developed to assist anyone working with vacuum technology. These briefs are not meant to take the place of formalized vacuum training or one of the many good textbooks which are currently available. If there's something you'd like specific information about, contact us and we'll do our best to assist you.
The Hidden Cost of Operating Obsolete PVD & E-Beam Power Supplies
We see them all the time…30, 40 and 50 year old DC power supplies used by commercial companies in sputtering and electron beam evaporation processes. It’s a sad fact that users of obsolete power supplies do not always understand the real cost (i.e. risk) associated with very old equipment. Electronic components in the aged power supply circuits are no longer operating within the performance envelope they were designed for. As a result, circuits designed to deal with shorts and spikes in the process are compromised. The consequence is that the power supply is not protecting itself or ensuring a smoothly running process.
What are you to do when a power supply failure occurs or when it becomes obvious that it is no longer ensuring a smoothly running process?
If the manufacturer still exists (and some are no longer in business), it’s unlikely they will support a repair, because in many instances, the electronic components are no longer available. Assuming you have (or can obtain) schematics, you are then on your own to troubleshoot the problem and conduct the repair, or find the semi-retired 80 year old who may know how to repair old power supplies…with questionable components from his bone pile.
Because you don’t have a viable alternative, your production is at a standstill.
Some questions for consideration:
1. What is an erratic process costing the company in rejects, rework and scrap?
2. What is each day’s lost production costing the company?
3. Are there better and cost-effective solutions to these power supply problems?
We can answer question 3 in three words: High Voltage Concepts.
Unlike manufacturers for whom DC power supplies for sputtering and electron beam deposition represent a tiny portion of their overall business, the vast majority of High Voltage Concepts’ business is derived from the manufacture of these products. They have the backs of their customers.
Thus, HVC –
Is equipped to optimize the way their products are designed, engineered and manufactured.
Is privately held, and free to make customer-focused decisions.
Knows the importance of building reliable products that are attractively priced and fully warranted.
Manufactures and supports its products in the USA. You never wait weeks or months.

How Accurate Are My Vacuum Gauges?
We know that vacuum processes can and do drift over time. When that happens, our scrap rates increase and the bottom line shrinks.
As vacuum gauges age or become contaminated, measurement inaccuracy creeps into the process envelope, until we're no longer operating within the tolerances of the process. The result is scrap, not salable product.
The obvious point is to know when to service or replace vacuum gauges that are no longer dependable.
The solution is to have a Certified Master Gauge whose sole purpose is to have its reading compared to that of the 'working' gauge installed in the process equipment.
Thyracont offers many models of self-contained vacuum measurement instruments that are proving their worth in hundreds of unique applications around the world. These instruments feature bright LCD displays, are easy to use and delivered in rugged foam-lined carry cases with everything needed to be Certified Master Gauges.
Certified Master Gauges are available in the following instruments:
VD81 - Handheld Vacuum Meter / Data Logger - Range:1200 Torr to 1 Torr
VD85 - Handheld Vacuum Meter / Data Logger - Range: 900 Torr to 0.5 MilliTorr
VSR Transducer - Range: 900 Torr to 0.5 MilliTorr
VSM Transducer - Range: 760 Torr to 5 x 10-9 Torr
All Thyracont Instruments carry a Two Year Warranty and are CE Marked.
