What is the metal encasement around military and civilian aircrafts#92; missiles microcercetry. I know its a possable gold alloy? It is heavy, gold in color and contains incredably small microcercetry. Each encasement is square, with a very thin lid on one side. All encasement material is gold in color including the lid wich is the same square shape of the encasement .There are slit openings down the sides of these encasements wich are full of pinns in a row to recieve wiring harness pluggs. I Need to know what the metal is made of. Heavy.each component or microcercetry encasement is about the size of a tick- tack box and about the same shape and has mounting holes raised of the corner edges for screws. These encasements are noticably Very high tech looking and very heavy for such a small item! The metal is not coted with gold as they scratch and are solid. They are stamped with numbers in purple ink RAYTHEON What are these metal encasements made of?????????
It means OMG. People just use it because E sounds like G. People do that so that some people that might be looking get confused.
I can't tell from your description what the package looks like. Does it have little flat wires (leads) extending from the package? On two sides or four? Do the leads come out from the middle of the package, and are encased in glass, or are they brazed to the top, side, or bottom of the package? In general, hermetic (non-plastic) integrated circuit packages are made of multilayer alumina ceramic. The conductors, including a ring on the top or bottom surface of the package to solder the lid, are screened conductive tungsten based ink. After the packages are fired in a high temp furnace, they (technically just the exposed conductive ink) are electroplated with gold. The lid used to be made from Invar, or Kovar, but is now likely Alloy 42. All three are nickel alloys that have limited thermal expansion with temperature and form oxides to which you can bond. The lid is electroplated with pure gold. The lid comes from the supplier with a gold-tin eutectic solder ring on it, and is put in a furnace to reflow the solder [no flux required, as the gold doesn't oxidize (much)]. I think the lid is about 0.010-inch thick, I can't recall off hand. If you think the lid is solid gold, try using a magnet on it. Only Nickel, cobalt, and iron are ferromagnetic among the elements. If it sticks to the magnet, that is proof it is not gold. This stuff is not secret; Kyocera is the largest manufacturer, you can look up their products, they probably have an online catalog now. I'm not sure about your microwave shielding theories. I worked on digital circuits, pretty much immune to interference. Low signal analog signals would be sensitive to interference though. I would expect magnetic material to be great for minimizing interference for most frequencies.
