Original factory and top PCB

What should we do if the PCB pad is soldered off?

1. The pad falls off during  custom pcb cost fabrication soldering because the soldering time is too long or the temperature is too high due to repeated soldering, and the copper pad of the pad will fall off after repeated expansion. Pay more attention to this to prevent more falling off when soldering.
2. Cut off the land on the High Quality Prototype PCB Fabrication with a knife and cut it to the place where it did not fall off to prevent the circuit from expanding along the fall off. If your component pins are long enough, you can scrape off the insulating paint at the circuit joints after cutting. Apply good solder to solder the pins of the foresight here.
3. If your component pin is not long enough, you can use a piece of thin wire to pass the solder through the pad hole and then solder it to the component pin, and solder the other end to the pad joint and use hot melt glue to fix it to prevent reopening. Welding falls off.
4. If the Quick-turn PCB Prototypes pad falls off very seriously, you can also choose the flying lead method, solder one end of the wire to the component pin of the desoldering, and solder the other end to any solder joint connected to the desoldering pad.
5. There is another way, bridging. If there are components on the same circuit around the soldered pad component pin, you can directly solder the component pin to the pin of that component, and discard the original pad. Of course, solder Be sure to see that you can’t solder the string to prevent burnout of the components.
