Since 1996
 SUN MEDIA has installed Microfab Inkjet Printer (Jetlab 4 XL ) for printed electronic devices like Solar cells and thin film transistors and also a new Xenon Photonic Curing System ( Sinetron 2000-S ) for Sintering of Nanoparticles at IIT Powai, Bombay.     
An Electron Beam is a versatile tool whose effect is primarily based on a short-duration, localized input of heat into a substrate material. An important advantage of electron beam welding is the ability to be able to weld materials down to considerable depths: although strongly absorbed by the material, the electron beam is able to penetrate deep into the material due to the deep-weld effect. This makes this technique an ideal tool for joining combinations of materials.
