Embodiment 1
[0026] A method for preventing an electroplated tin layer from being oxidized, comprising the following steps
[0027] 1) Select a suitable size tank, add pure water to the size of the tank;
[0028] 2) Weigh the alkylphenol polyoxyethylene ether phosphate, and dissolve it in the purified water of step 1) to obtain a solution, wherein the concentration of the alkylphenol polyoxyethylene ether phosphate is 0.2g / L;
[0029] 3) Pour the solution obtained in step 2) into the use tank to build a bath, and at room temperature, soak the tinned device for 60 seconds and then wash it with water.
[0030] Further, in the step 2) after weighing the alkylphenol polyoxyethylene ether phosphate, dissolve it in a small amount of pure water at a temperature of 40°C to obtain an aqueous solution of the alkylphenol polyoxyethylene ether phosphate, and then pour it into Purified water in step 1).
[0031] Further, the alkylphenol polyoxyethylene ether phosphate is octylphenol polyoxyethylene e...
Embodiment 2
[0039] A method for preventing an electroplated tin layer from being oxidized, comprising the following steps
[0040] 1) Select a suitable size tank, add pure water to the size of the tank;
[0041] 2) Weigh the alkylphenol polyoxyethylene ether phosphate, and dissolve it in the purified water of step 1) to obtain a solution, wherein the concentration of the alkylphenol polyoxyethylene ether phosphate is 0.4g / L;
[0042] 3) Pour the solution obtained in step 2) into the use tank to build a bath, and at room temperature, soak the tinned device for 60 seconds and then wash it with water.
[0043] Further, in the step 2) after weighing the alkylphenol polyoxyethylene ether phosphate, dissolve it in a small amount of pure water at a temperature of 45°C to obtain an aqueous solution of the alkylphenol polyoxyethylene ether phosphate, and then pour it into Purified water in step 1).
[0044] Further, the alkylphenol polyoxyethylene ether phosphate is octylphenol polyoxyethylene e...
Embodiment 3
[0052] The difference between embodiment 3 and embodiment is that a method for preventing the electroplated tin layer from being oxidized comprises the following steps
[0053] 1) Select a suitable size tank, add pure water to the size of the tank;
[0054] 2) Weigh the alkylphenol polyoxyethylene ether phosphate, and dissolve it in the purified water of step 1) to obtain a solution, wherein the concentration of the alkylphenol polyoxyethylene ether phosphate is 0.4g / L;
[0055] 3) Pour the solution obtained in step 2) into the use tank to build a bath, and at room temperature, soak the tinned device for 40 seconds and then wash it with water.
