Description

Technical Field

[0001] The utility model relates to an improved structure of a composite gold resistor, which mainly provides a resistor structure assembled with a printed circuit board, so as to provide a stable current flow by a certain ratio value between the overall width and the width of the composite gold piece. Background Art

[0002] According to the current application of printed circuit boards, they have become one of the indispensable components in electronic products. In order to better apply printed circuit boards, they must be matched with appropriate resistance components to enable the current to flow stably and smoothly.

[0003] At present, the combination of printed circuit boards and alloy resistor components is usually carried out in the form of solder pads. The alloy resistor is mainly used to hinder the flow of current and is used to feedback the changing current in the circuit. The resistance value only depends on the resistivity of the conductive material and its thickness, size, etc. Therefore, the circuit performance can only be achieved by impedance matching to keep the signal stable during high-speed transmission; although the alloy resistor has the characteristics of low resistance, high stability, and high power, the strong metal conductivity of the alloy resistor can easily cause the performance of the entire board to be unstable, thereby increasing the time waste of the operation procedure and adjustment. Therefore, it is necessary to consider the stable alloy resistor mode in the operation to control the impedance value within a certain range. Therefore, it is necessary to propose specific improvement plans to meet the needs of industrial progress and further provide users with more choices. Utility Model Content

[0004] The main purpose of the utility model is to provide an improved structure of a composite gold resistor, which forms a certain width ratio between the composite gold piece and the metal piece to achieve a stable output of the impedance value and achieve the purpose of meeting the product quality.

[0005] In order to achieve the above-mentioned purpose, the utility model specifically implements the following technical means and solutions:

[0006] An improved structure of a composite gold resistor comprises: a composite gold piece, which is rectangular in shape and has a rectangular notch at the bottom; two metal pieces, which are arranged on two sides of the composite gold piece and are arranged correspondingly to form a composite gold resistor, wherein the overall width of the composite gold resistor is A value, the width of the composite gold piece is B value, the height of the metal piece is C value, and the height of the rectangular notch is D value; the ratio of the aforementioned A value: B value is 1.8:1, and the ratio of the aforementioned C value: D value is 4:1.

[0007] The ratio of the overall width to the composite metal width is set to provide a stable current flow. When the composite metal resistor device is assembled on a printed circuit board for current flow, it has the effect of reducing energy consumption and stabilizing voltage.
