WHY DO SOME PEOPLE BUY OLD AND DAMAGED IC, LSIC AND TRANSISTOR?
It is because IC, Large scale IC, Very large scale IC like our computer CPU and Transistors have fine gold wire inside them. Gold is use to connect or bond all the outside pins of an IC and transistor to their inside part, like gate, emitter, and base of a transistor. CPU LSIC consist of millions of transistors and related parts in about a 1 3/4 X 1 3/4 package. Without fine gold wire you can not soldered the exact point. They are sold in grams I guest and not a good thing to collect!
