One of the most common defects when soldering is insufficient wetting of the pad. This can happen for a variety of reasons, but the most common is simply not using enough solder. When you don’t use enough solder, it doesn’t flow evenly over the pad and can cause dry spots.
Too much solder can lead to accidental connections. Second, be careful when handling the soldering iron. Avoid touching the tip of the iron to anything other than the solder joint. Finally, use flux-core solder if possible. This type of solder helps prevent bridges by filling in any gaps between the metals.
One of the most common soldering defects is solder starvation. This occurs when there is not enough solder on the joint to create a good connection. This can be caused by several factors, including incorrect pad design, poor soldermask quality, or insufficient solder paste coverage. There are several ways to spot solder starvation.
A faulty pump will have ineffective suction, resulting in a severe recoil of the pump which can cause the tip to knock the iron onto the pads. Solder bridges form when excess solder connects adjacent pads or pins that should not be connected.
This movement can be an unstable work surface or human error which will cause the solder to become distressed before it has completely solidified. The result is a weak bond that might not conduct electricity reliably or hold up to physical stress.
When soldering pins, such as those on through-hole components or connectors, it’s crucial that the solder forms a good connection around each pin. If a pin isn’t properly wetted, it might not make a secure electrical connection.
I removed the battery from the board, and roughed up the top of the battery so the solder could sick. I then tried tinning it - but the solder refused to flow. It just balled up.
Discharge Battery First. Before soldering, it''s best to discharge the Li-Ion battery down to 3V. The more energy stored in the battery, the more dangerous when things go wrong. 3V is the minimal safe voltage for 18650 to …
