Is it Safe to Solder Li-Ion Battery Wires to PCB?
When working on a small form-factor wearable device powered by a 120mAh single-cell Li-Ion battery, the question arises: is it safe to solder the wires from the integrated PCB on the battery to the main PCB without using a connector?
Some suggest avoiding soldering under any circumstances, while others propose cautious soldering techniques. The debate stems from varying information in Li-Ion battery datasheets.
Given the importance of safety, especially when dealing with batteries, it’s crucial to consider the risks involved in soldering these connections. The soldering iron temperature and technique play a significant role in ensuring a secure connection without compromising safety.
Considerations for Soldering Li-Ion Battery Connections
- Keep the soldering iron temperature to a minimum
- Ensure quick and precise soldering to minimize heat exposure
- Refer to the Li-Ion battery datasheet for specific guidelines
It’s essential to prioritize safety when soldering Li-Ion battery connections to your PCB. Consulting with experts or seeking professional advice can provide further clarity on the best practices for this process.
By taking necessary precautions and following recommended guidelines, you can safely solder the wires from the integrated PCB on the battery to your PCB, ensuring the integrity of the connection and the overall safety of the device.
