Introduction to the development of printed circuit boards

    PCB circuit board, also known as printed circuit board, is an important electronic component that has developed from single-layer to double-sided, multi-layer and flexible, and still maintains its own development trend.
    With the continuous development of science and technology, due to the continuous development in the direction of high precision, high density and high reliability, continuous reduction of volume, cost reduction and performance improvement, printed boards still maintain a strong role in the development of electronic equipment in the future. vitality.
    A summary of the development trends of future printed board manufacturing technology at home and abroad is basically the same, that is, to high density, high precision, fine aperture, fine wire, fine pitch, high reliability, multi-layer, high-speed transmission, light weight, The development of thin type, in production, is to improve productivity, reduce costs, reduce pollution, and adapt to the direction of multi-variety and small batch production. The technical development level of printed circuits is generally represented by the line width, aperture, and board thickness/aperture ratio on the printed circuit board.
