Hind High Vacuum Advanced Technologies (HHVAT), a subsidiary of the Bengaluru-based HHV group, has announced that its Hybrid Micro Circuit (HMC) Lab has once again bagged the prestigious qualification validity certification from the Space Applications Centre (SAC), Indian Space Research Organisation ( ISRO) for its metallisation and lithography processes on alumina substrates for space flight applications.
SAC, one of the major centres of ISRO, focuses on the design of space-borne instruments for ISRO missions and development and operationalisation of applications of space technology for societal benefits. The applications cover communication, broadcasting, navigation, disaster monitoring, meteorology, oceanography, environment monitoring and natural resources survey.
The HHV Group has been associated with ISRO for the last six decades and has built and supplied India's first space simulation chamber. From providing machines and components for various applications, HHVAT has a long history with various ISRO units.
HHVAT's HMC lab is capable of two-layer and three-layer Thin Film Metallised Circuits (TFMC) with a line accuracy of 40 micron using photolithography process. The lab is equipped with three production sputter coating systems, a stylus profiler for measuring the thickness of the coatings, a four-probe sheet resistance metre to qualify the sheet resistance of the coatings, a laser writer for mask fabrication, UV exposure and aligner system for carrying out the photolithography process, an etching room with a chemical wet bench, dicing machines to cut metallised substrates to required sizes, and high-performance microscopes and profile projectors for inspection and measurement of the plain and patterned substrates.
The HMC Lab is housed in an ISO 7 clean room and has ISO 5 laminar flow stations for substrate handling. With these facilities the HMC lab can produce annually 25,000 numbers of 1 inch sq. metallised substrates for space and defence applications.
"HHV works closely with scientists of ISRO on these Hybrid Micro Circuits in realising various Flight Mode projects. The Chandrayaan-3's landing on the moon has made India proud and put a feather on the cap of HHVAT for its contribution towards Make in India. We are proud to be a part of this successful journey of ISRO and India" said Prasanth Sakhamuri, Managing Director, HHVAT.
