Products : Substrates for microelectronics circuits
Most applications for microelectronics circuits having to face high temperatures, retain dimension stability, or guarantee high electrical insulation, call for the use of alumina substrates in view of their interesting quality-cost-performance ratio. But aluminium nitride, quartz or sapphire substrates will be chosen when high thermal conductivity or when specific dielectric properties are required. Microcertec offers substrates that are manufactured by U.S-based company Accumet Engineering Corporation which has a 40-year recognized expertise in this field, and a wide range of equipment capable of delivering R&D as well as production quantities.
Applications
The main application for these substrates is the manufacturing of electrical circuits on one or two faces for such various fields as :
- the automotive and consumable goods
- industrial sensors
- medical equipment
- airborne microelectronics devices for the aerospace and defence.
Products
Microcertec offers customized substrates manufactured by Accumet Engineering Corporation in terms of thickness, flatness and roughness. Depending on customers' application we can offer :
- lapped substrates in 96 % alumina for thick-film metallized circuits
- polished substrates in fine-grain 99,6 % alumina for thin-film metalized circuits to be used in low to medium power RF and microwave devices
- aluminium nitride substrates that can be lapped or polished depending upon the metallization process for use in high-power RF and microwave devices
- fused silica substrates for high-frequency thin-film metallized circuits requiring low loss performance
- sapphire substrates that require optimum thermal dissipation.
Materials
The following materials can be processed :
- alumina 96 % (Al2O3)
- fine-grain alumina 99,6 % (Al2O3)
- aluminium nitride (AlN)
- fused silica
- saphirre
- beryllium oxide
- titanates
Accumet have a solid experience with these materials. Their expertise in lapping and polishing of substrates allows them to achieve very high levels of finish as regards to roughness, flatness, parallelism and thickness. For additional technical information please download our data sheets.
