DuPont MCM Introduces New Low Temp Co-Fired Ceramic
DuPont Microcircuit Materials (MCM) of Research Triangle Park, SC, USA has announced the introduction of the DuPont™ GreenTape™ 9K7 low temperature co-fired ceramic (LTCC) material system, designed for advanced high frequency, microwave and millimetre wave electronic circuit applications within the aerospace, automotive, military, consumer electronics and telecommunications industries.
DuPont™ GreenTape™ 9K7 LTCC material is a lead-free (in this context meaning that lead is not an intentional ingredient in and is not intentionally added to the referenced products but trace amounts however may be present) glass-ceramic dielectric tape, and is available with compatible gold and silver conductive materials as well as co-fired embedded resistor materials. MCM continues to expand its portfolio of LTCC and other materials systems which combine superior performance with preferred environmental properties.
“DuPont™ GreenTape™ 9K7 is ideal for electronic system designs which need to deliver a high-density, low-loss, cost-effective interconnect and packaging solution that performs with exceptionally high reliability,” said Scott Gordon, Americas regional marketing manager – DuPont Microcircuit Materials. “It’s also more robust in processing, with a stable dielectric constant even when refired, which for fabricators translates into greater consistency and higher yields for final circuits. These properties make GreenTape™ 9K7 a unique solution for leading-edge applications requiring RF and microwave frequencies, such as bluetooth, automotive safety radar systems and transceivers.”
LTCC technology has long provided circuit designers with the ability to further miniaturise high-density interconnect circuits but the development of a new proprietary crystallisable glass, with alumina fillers for added mechanical strength, has been a significant technical breakthrough with GreenTape™ 9K7. With this system, circuit designers and LTCC fabricators now have the ability to design and build high frequency microwave circuits up to 100 Gigahertz and beyond, using electronic materials that are improved over other commercial tape systems, demonstrating superior dielectric properties and improved process capability. All components of the new system are compatible, to facilitate their introduction into the manufacturing process.
DuPont Microcircuit Materials has over 40 years of experience in the development, manufacture, sale and support of specialised thick film compositions for a wide variety of electronic applications in the photovoltaic, automotive, biomedical, industrial, military and telecommunications markets.
