A rare metallic element, discovered in certain ores of zinc, by means of its characteristic spectrum of two indigo blue lines; hence, its name
Atomic number 49 on the Periodic Table of Elements Indium is a silvery metal that is very soft and malleable It has a low melting temperature and very good cyrogenic (very low temperature, well below the freezing point of water) properties We use indium to make bumps on our substrates for flip chip bonding (See Bump or Flip Chip Bonding above )
A metallic element with the symbol "In" and atomic number of 49 It is used in the manufacture of transistors and as a bonding material for acoustic transducers
In appearance it resembles zinc, being white or lead gray, soft, malleable and easily fusible, but in its chemical relation it resembles aluminium or gallium
Chemical symbol In Grayish-white minor metal obtained by treating smelter flue dusts and slags or other residue of base metal concentrates Capable of marking paper (just as lead does), indium is used in low-melting alloys, solders, electrical contact coatings, infrared detectors, nuclear reactor control rods, and various electronic components
