See some friends will ask the circuit board of the pad welding off how to do, how to deal with? Circuit board proofing manufacturers have also encountered the same situation in the production of

circuit boards, and today we will share some of the experience summed up in this situation with you.

When the circuit board is welding, the pad falls off because the welding time is too long or the temperature is too high because of repeated welding, the copper sheet of the circuit board will fall off

after repeated expansion, and more attention should be paid to this to prevent more falling off when welding.

The circuit board will be cut off the pad with a knife to the unshed, to prevent the circuit from expanding along the shed, if your component pin is long enough, you can scrape the insulation paint off

the cut circuit junction, and solder the visionary pin here. If your PCB component pin is not long enough, you can use a thin wire to solder the solder along the pad hole and weld it to the component

pin, and the other end is welded to the pad joint and fixed with hot melt adhesive to prevent it from falling off again

If your circuit board pad falls out seriously and does not fit the above method, you can also choose to fly wire method, weld one end of the wire to the detached component pin, and weld the other

end to any solder joint connected to the detached pad. There is also a way, bridge, if there are components on the same line around the pin of the welding pad element, you can directly weld the pin

of the component to the pin of that component, scrap the original pad, of course, when welding, be sure to see that the can not be welded string to prevent burning components
