    Abstract: Disclosed is a method of forming electroless metal plating layers on one single surface of a plastic substrate and the product thereof. The method includes steps of degreasing or pre-etching the material for forming the substrate, etching the material, adding catalysis, activating, drying, spraying non-conducting paint on a first surface of the material, accelerating, forming an electroless copper plating layer on a second surface of the material, activating, forming an electroless nickel plating layer on the second surface of the material, sealing, dehydrating, drying, inspecting, and packing. Wherein, the steps of spraying non-conducting paint and drying give the material a beautiful painted appearance on the first surface thereof. The non-conducting paint on the first surface of the material facilitates easy formation of smooth electroless copper and nickel plating layers on the second surface of the material. Therefore, a product of the method can be used in electronic products requiring high sensitivity.

    Abstract: A single chip replacement upgradeable/downgradeable data processing system capable of operating with different types of central processing unit (CPU) chips. The system has a first socket for registration of a first CPU chip and a second socket for registration of a second CPU chip. Circuitry is provided for preventing possible signal contention between the first and second CPU chips and for synchronizing clocks for operating a CPU with the system clock. Circuitry is also provided for interfacing with a coprocessor associated with the different types of CPU chips as well as for adjusting the signals to and from the CPU chips to the signal width of the system.
