| 46 | Low-cost keypad encoding circuit | US10359405 | 2003-02-05 | US07391342B1 | 2008-06-24 | Daniel SauFu Mui |
| A keypad encoding circuit contains a voltage dividing network and an integrated circuit. The voltage dividing network includes a string of resistors that generates an encoding signal voltage. The integrated circuit converts the encoding signal voltage into a digital value indicative of which of the keys has been pressed. The cost of the voltage dividing network is reduced by forming the resistors from a layer of conductive carbon and avoiding the cost of providing discrete resistors. Each resistor has the same resistance even where the dimensions of the conductive carbon patches that form the resistors vary. Providing the resistors does not involve additional manufacturing cost because the resistors are made in the same step as are the landing pads of the voltage dividing circuit. Manufacturing costs associated with etched printed circuit board layers are avoided because inexpensive printed layers are used to realize the required traces and resistors. | ||||||

| This invention discloses a preparation method for precious metal switching contact components by means of plating masking, plating and etching processes. The plating masking process is performed by using a plating mask ink with or without a photo exposure machine. Plating of precious metals is performed by electroless plating or electro plating methods. Etching is carried out with etching solutions containing weak organic acids, weak inorganic acids or acidic buffering agents. Improvement of the etched surface gloss and prevention of the side etching are realized with the sulfur-contained compounds. The dust- and oil stain-resistances of the switch contacts are improved by increasing the etching depth. The switch contacts made by this invention are featured with the advantages of good reliability, good resistance to dust and oil stain, short contact bounce time, long service life, low cost of raw materials and so on. | ||||||
