How to deal with PCB solder pads that have been soldered off! Security monitoring circuit board
Release time:

When soldering a circuit board, the solder pads often fall off due to prolonged soldering time or excessive temperature caused by repeated soldering. The copper plates on the solder pads of the circuit board expand repeatedly before falling off. It is important to pay more attention to this during soldering to prevent further detachment.
When soldering a circuit board, the solder pads often fall off due to prolonged soldering time or excessive temperature caused by repeated soldering. The copper plates on the solder pads of the circuit board expand repeatedly before falling off. It is important to pay more attention to this during soldering to prevent further detachment.
The circuit board uses a knife to cut off the detached solder pads to the non detached area, preventing the circuit from expanding along the detached area. If your component pins are long enough, you can scrape off the insulation paint at the cut circuit joints and apply good soldering to solder the farsighted pins here. If your PCB circuit board component pins are not long enough, you can use a thin wire to apply good soldering along the solder pad hole and then weld it to the component pins, The other end is welded to the solder pad joint and fixed with hot melt adhesive to prevent further welding and detachment
If the detachment of the solder pads on your circuit board is very serious and not suitable for the above method, you can also choose to use a flying wire method. One end of the wire is soldered onto the pins of the soldered components, and the other end is soldered onto any solder joint connected to the soldered pads. There is also a way to bridge, if there are components on the same circuit around the pins of the soldered components on the soldered pads, you can directly solder the component pins onto the pins of that component, Discard the original solder pad, of course, it must be clearly visible during welding to prevent burning out of the components
