Embodiment 1
[0045] Embodiment 1: as figure 2 An ultra-low resistance chip resistor of a typical chip resistor model 6432-1 is shown. The resistance value of the ultra-low resistance chip resistor is 1 milliohm. The manufacturing method includes the following steps:
[0046] Step 1) Take a pure nickel strip with a thickness of 0.05mm, the weight percentage of nickel is Ni≥99.9%, take a pure copper strip with a thickness of 1.0mm, and the weight percentage of copper is Cu≥99.9%, and take a thickness of 1.5mm precision resistance alloy strip, the material of the precision resistance alloy strip is one of manganese copper or copper nickel or constantan or nickel-chromium resistance alloy, and its typical grades are 6J8, 6J12, 6J13, 6J40, 6J20, 6J22, 6J23, CuMnSn, germanium-manganese-copper, etc. In this example, the typical grade of 6J8 manganese-copper alloy strip is selected. After the surface is cleaned and cleaned, the nickel strip is used as the upper layer, the copper strip is used as...
Embodiment 2
[0054] Embodiment 2: as image 3 As shown, an ultra-low resistance chip resistor of a typical chip resistor model 3216-3, the resistance value of the ultra-low resistance chip resistor is 3 milliohms, and its manufacturing method includes the following steps:
[0055] Step 1) Take a pure nickel strip with a thickness of 0.05mm, the weight percentage of nickel is Ni≥99.9%, take a pure copper strip with a thickness of 1.0mm, and the weight percentage of copper is Cu≥99.9%, and take a thickness of 1.5mm precision resistance alloy strip, the material of the precision resistance alloy strip is one of manganese copper or copper nickel or constantan or nickel-chromium resistance alloy, and its typical grades are 6J8, 6J12, 6J13, 6J40, 6J20, 6J22, 6J23, CuMnSn, germanium-manganese-copper, etc. In this example, a copper-nickel alloy strip with a typical grade of 6J40 is selected. After the surface is cleaned and cleaned, the nickel strip is used as the upper layer, the copper strip is...
