Semiconductor continually refined reduction techniques, many of the original packages need to use more discrete components in order to constitute the circuit, but now live can use a highly integrated chips to replace, so some people gradually bearish printed circuit board technology. Theory is true, but the actual development is at odds with the theory of … …
Some people believe that printed circuit board (known as the Mainland of China: printed circuit) technology will become increasingly important, mainly because there is a 2:1, with the semiconductor process technology continues to improve, which requires multiple chips can be achieved effectiveness of, and now stars as long as the 1,2-integrated chip can be completed, as in the past need chipset (Chipsets) circuit can be achieved, but now available SoC (System-on-a-Chip; SoC) to achieve, so so that the number of wiring between chips declining.
Another reason is to speed up data transfer between chips, past parallel-type transmission interface is constantly being replaced by serial transmission interface, today’s high-speed serial multi-frequency approach includes mining can enjoy quickly transfer data, and the than those without parallel transmission crosstalk (Crosstalk) problem. For example, ATA into SATA, PCI into PCIExpress, SCSI into SAS, RapidI / O parallel version of the serial version of the conversion … so are examples.
So we should consider the printed citcuit board technology is also very impotant, we can’t leave it in our life.
