A plurality of main circuits (103) is located on the circuit board, and a plurality of electrically conductive second vias is defined in the circuit board, and is electrically connected with the main circuits respectively. A plurality of resistors is removably connected between corresponding main circuits and terminal circuits. A method for redefining terminal connections of the expansion card is also provided.
Claims13
An expansion card, comprising:
- a circuit board defining at least two electrically conductive first vias and at least one electrically conductive second via;
- at least two terminal circuits located on the circuit board, the terminal circuits electrically connected with the first vias respectively;
- at least one main circuit located on the circuit board, the main circuit electrically connected with the second via;
- and
- at least one resistor removably connected between the main circuit and one of the terminal circuits.
A method for redefining terminal connections of an expansion card, the method comprising the steps of:
- removing a first resistor connected between a first main circuit and a first terminal circuit of the expansion card;
- providing a first electrical conductor;
- and
- electrically connecting the first electrical conductor between an electrically conductive second via electrically connected with the first main circuit and an electrically conductive first via electrically connected with a second terminal circuit which needs to be redefined.
A method for redefining terminal connections of an electronic part, comprising the steps of:
- assigning a plurality of predefined terminals of an electronic part to a plurality of corresponding main circuits of said electronic part respectively;
- setting up a removable electrical connection between each of said plurality of terminals and corresponding each of said plurality of main circuit so that said each of said plurality of terminals and said corresponding each of said plurality of main circuit are capable of being electrically disconnected by removing said connection;
- providing an electrically connecting means for said each of said plurality of terminals and said each of said plurality of main circuits;
- and
- reassigning a user-selected terminal out of said plurality of terminals to a newly corresponding main circuit out of said plurality of main circuits by means of disconnecting said electrical connection between said user-selected terminal and an originally-assigned corresponding main circuit, and electrically connecting said user-selected terminal with said newly corresponding main circuit via said electrically connecting means thereof.
