Thanks for the article, its very informative...!!

May i know the working of COB chip how it converts the signals into DC in the keyboard...??

Friend.The COB(Chip On Board) is just any IC or microcontroller covered by epoxy coating.This reduces the cost of packaging.I think it should be any encoder circuit that converts signals from the keyboard into ASCII codes.


What is the technical name of the plastic sheet which use inside of the keyboard?
