The application of tinned copper busbars can now be said to be very extensive. So, does everyone have an understanding of the manufacturing process of tinned copper busbars? Generally, it first involves sanding with sandpaper and then rinsing. This sanding step is also quite crucial as it affects the subsequent tin-plating effect. NextCopper bus manufacturerI will give everyone a detailed introduction to the specific operations and precautions of tin plating by brushing.

1. Tin Plating:

1. Voltage 3~8V, it is recommended to use 3.5V, connect the brush plating pen to the positive pole, and the copper busbar to the negative pole;

Electroplate until a uniform tin layer appears, with a thickness rate of approximately 8 μm/min per three times the contact area;

If the movement speed is too fast, the coating will be thin; if too slow, it will burn black. Recommend 20cm/s, which can also be practiced and summarized.  

2. For running water washing, it is recommended to use a spray head for cleaning.  

3. Wipe dry with a clean cotton cloth or blow dry with a compressed air gun.

II. Usage method of brush plating pen:

Place a layer of degreased cotton approximately 1 centimeter thick on the plating brush working surface (applicable for single-sided or double-sided); wrap it with a cloth (with the fuzzy side out), then sew or tie it with thread or straps, and soak it fully in the plating solution before use. During use, intermittently dip it in the solution to ensure the cotton remains fully saturated. The plating brush should be disassembled and cleaned once a day, discard the degreased cotton, and the outer cloth can be washed and used again.

3. Precautions:

If the tin layer turns black, there are three reasons: a. The copper surface is too dirty or the plating layer is too thin; b. After brushing tin plating, the washing is not thorough; c. The degreasing cotton in the brush is too old and hard or too thin and needs replacement.

After each piece is completed, dry it in the sun, blow it dry with a compressed air gun, and do not wipe it with a dirty cloth.

This process is neutral and suitable for long copper busbar tin plating. If other brush plating processes such as tin or silver are required, please contact us.

The above covers all the details regarding the specific operation process and precautions for brush plating. The step of brush tin plating is quite a test of the operator's skill, and mastering the right degree requires continuous practice and summarization. Only in this way can relatively fine tin-plated copper busbars be produced.
