Fine Line Etching of Lead Frames

Fine Line Etching of Lead Frames Lead frame manufacture has become onc of the fastest growing segments of the photo-chemical machining industry teday. Much of the interconnect circuitry and components lhat used to go on the printed circuit board now goes directly on the chip and the chips themselves are getting smaller. In short, electronic designers are saving space on the printed circuit board surface by putting some of its functions in the chip. This means, however, that more chips are being used which in turn means more lead frames are needed to make the interconnection with the circuit card which communicates with all the other chips. The growth in demand in the past three years has been phenomenal and several large manufachirers in Asia estimate that they will have to expand their production eight times by the year 2000 to keep up.
