What are the precautions for soldering chip capacitors? Since some chip capacitors are very small, in order to avoid damage to the chip capacitors during soldering, editor Zhi Shengxiang talks about the precautions when soldering chip capacitors:

1. Precautions for reflow soldering

1. The ideal amount of solder should be 1/2 or 1/3 of the thickness of the capacitor.

2. Too long solder dip time will damage the solderability of the capacitor, so the soldering time should be as close as possible to the recommended time.

Two, wave soldering precautions

1. Ensure that the capacitor has been fully preheated.

2. The temperature difference between the capacitor and the molten solder cannot be greater than 100°C to 130°C.

3. The cooling method after welding should be natural cooling as much as possible.

4. Capacitors specified to be only available for reflow soldering cannot be used for wave soldering.

Three, manual welding matters needing attention

1. The maximum diameter of the tip of the soldering iron used is 1.0mm.

2. The soldering iron cannot directly touch the capacitor (wave soldering).

Use reflow soldering as much as possible for soldering chip capacitors, or wave soldering. If you do not choose, you must use manual soldering. Remember that the soldering iron cannot directly touch the chip capacitors, because the high temperature of the soldering iron can easily damage the components. Large-size MLCCs can be fully preheated by the stage.
