Are there any quality issues I should know about?

INTA Technologies is ISO 9001:2000 certified and takes quality very seriously. Our QMS and QP are strictly adhered to and we undergo frequent internal audits and periodic external audits. One of our quality goals is to eliminate customer returns and we use continuous improvement and monitor quality. Documentation and identification are two keys to INTA’s quality success. All parts are clearly identified and traced via software and paper trail from the moment the material enters the facility until the moment it exits the loading dock.

What is INTA’s stance on SEM?

SEM (supplier ethics management) is critical to the success of INTA Technologies’ business model. Since 1978, INTA has been providing quality products and services to the community and part of our commitment to the community includes SEM. All of our suppliers are closely monitored by our purchasing agent Chet Dwyer. A scorecard is kept and ratings are made based on certain criteria. SEM is important because ultimately INTA is responsible for the finished goods. INTA stays in close contact with suppliers and periodically checks documentation such as material certifications and inspection records.

How does INTA protect customer supplied property?

INTA supplies many materials such as machined components, copper tungsten and metallized ceramic but many customers supply their own materials to INTA for processing. In this case, INTA is responsible to store and properly care for the customer owned property. To ensure adequate steps are taken INTA performs the following steps:

Documents incoming material

Keeps inventory

Identifies materials clearly at all points in the facility

Stores material in an approved container and environment

Pack material in protective packaging for shipping

Other

What is the standard lead time for feedthroughs?

Lead times vary but please allow at least four (4) weeks for simple projects if INTA is to supply all materials. If the customer is to supply all the machined components, please allow at least two (2) to three (3) weeks for tooling and manufacturing. Lead times are found on quotations. To request a quotation send the drawings, specifications, desired quantities, target pricing and other notes to sales@intatech.com

What materials should I use for my feedthrough design?

Some common materials include:

Alumina (96% min Al2O3)

Kovar (iron-nickel-cobalt)

Stainless steel

Copper (Cu101 or Cu102)

Other

 

Some other less common materials include:

What type of plating is ideal for vacuum?

Many types of plating work well in vacuum, it really depends on the substrate, surface finish, level of vacuum, coating structure and other factors. The designer may wish to avoid coatings with low melting points such as Indium and Tin because they may evaporate if the temperature rises above 156 deg C for In and 231 deg C for Sn. Metals with higher melting points are preferred. Better options include:

 

Rhodium

Platinum

Gold

Nickel

Silver

Copper

Palladium

Are there any good references relating to vacuum and similar technologies?

Check your local library and VT&C Magazine (Vacuum Technology and Coating).

 

Keep in mind, for gold-plated items, INTA recommends 300u" min thickness to avoid pinholes and possible subsequent outgassing. For more detailed information regarding ceramic applications in vacuum, please review INTA’s entire website and also visit the homepage of Superior Technical Ceramics. INTA Technologies Corporation and Superior Technical Ceramics are sister companies. If you need help with a specific question, please contact B.Kneedler, Manufacturing Engineer 408-748-9955 x113 or blake@intatech.com
