When the soldering time of the circuit board is too long or the temperature of the circuit board is too high due to repeated soldering, the copper pad of the circuit board may repeatedly expand and then fall off. Pay more attention to this point when soldering to prevent more falling off. Then, the circuit board What is the remedy for the pad falling off? Follow the editor of Purifier circuit board Wholesale Price to have a simple look!

The circuit board cuts off the peeled pads with a knife and cuts them to the place where they are not peeled off to prevent the circuit from expanding along the peeling place. If your component pins are long enough, you can scrape off the insulating varnish at the circuit joints after blocking, and finish it. Solder the far-sighted pins here. If your PCB circuit board component pins are not long enough, you can use a piece of thin wire to pass the solder through the pad hole and then solder to the component pins, and solder the other end to the soldering Use hot melt glue to fix the joints of the disk to prevent re-opening and falling off
If the pad of your circuit board comes off very severely, you can also choose the flying lead method. Solder one end of the wire to the pin of the desoldered component, and the other end is soldered to the pad connected to the desoldered pad. On any solder joints. There is another way, bridging. If there are components on a unified circuit near the soldered pad component pins, you can directly solder the component pins to the pins of that component and discard the original pads. Of course, when soldering, you must see clearly that you cannot solder the string to prevent burnout of the components.
The above is the editor of Purifier circuit board Wholesale Price: about the remedy of the circuit board pad falling off.
