Indian Scientists have indigenously developed toxic-free and superior multilayer technology that packages together electronic components like resistors, capacitors to produce multilayer circuits.
Details of new technology
- These technologies, known as Low-Temperature Cofired Ceramic (LTCC) and High-Temperature Cofired Ceramic HTCC substrates with applications as satellite communication components, are currently being imported in India.
- The indigenous development can plug the money drain through import substitution and support the country’s strategic sectors.
- Low orbit satellites satellite systems which are in demand today need a sustainable technology supporting reduced satellite volume and mass, besides reduced production time and affordable cost.
- Hybrid microsystems based on LTCC technology (integration of passive components, such as a capacitor, resistor, inductor, resonator and filter, etc., into a multilayered ceramic module) is an interesting solution in future communication satellites due to their outstanding performance and moderate cost.
- Currently, the LTCC products are being imported from vendors like DuPont, Ferro etc., and hence country’s revenue is getting drained owing to the exorbitant price of these products.
- They have dielectric properties or the ability of storing electric energy in an electric field that are comparable to the commercial tapes, whereas thermal conductivity is better than them.
- An aqueous tape casting technique has been developed, which is relatively health hazard free since it does not employ volatile organic components like xylene and methyl ethyl ketone.
- The technology developed is a glass-free LTCC tape casting composition, which can address the brutality issues of tapes.
Application
These tapes find application in various satellite communication components at the Space Application Centre, Ahmedabad (ISRO), which require thousands of microwave substrates every year as also in Deference Research laboratories and BHEL.
