Production Notes
1. The soldering time should not be too long, 1-3 seconds, otherwise the copper sheet will fall off. If it is not soldered once, remove the soldering iron and solder it again. Be sure to be optimistic about the production pictures and text, distinguish the positive and negative poles, and pay attention to the white silk screen welding of the corresponding components when welding;
2. The vibration switch must be close to the circuit board, and cannot be high on one side and low on the other;
