Repairing missing pads with the soldering lug no longer requires the complex jumping wire. The soldering lug itself already features pads with various shapes and sizes, simplifying the traditional repair way. The soldering lug can be placed directly on the missing pads, which is efficient and convenient with stable soldering.<\/p>\n\n\n\n In addition, the soldering lug is suitable for different sizes of pads and the handwork requirement is much lower than the jumping wire.<\/p>\n\n\n\n Next, we will share how to use the REFOX soldering lug with a repair case.<\/p>\n\n\n\n Peel off the copper foil and there are pads with different sizes and shapes. The thickness of the pad is only 0.02 mm, which can be used to repair all kinds of motherboard and IC.<\/p>\n\n\n\n First of all, we need to find pads with the same size. Scrape to show the circuits of the missing pads with Sculpture Knife<\/a> blade 11.<\/p>\n\n\n\n Apply some middle-temperature Solder Paste and heat with Hot Air Gun<\/a> at 340 \u00b0C to form solder balls.<\/p>\n\n\n\n Please be noted that solder balls must be soldered firmly with uniform size. If the size is too small, the pads can\u2019t be soldered firmly. If the size is too big, the pads can\u2019t be soldered evenly. Clean the pads with PCB Cleaner and apply some rosin. Align the pads. To avoid blowing away the pads, set the airflow of the hot air gun to 1. Then heat with Hot Air Gun<\/a> at 340 \u00b0C and nudge the pads with tweezers. Clean the pads again with PCB Cleaner after the motherboard has cooled.<\/p>\n\n\n\n Apply some Solder Mask<\/a> evenly on the missing pads that need repair. Solidify with UV Lamp<\/a> for 5 minutes and scrape away excess solder mask with Sculpture Knife blade 11 to show the pads.<\/p>\n\n\n\n It can be seen that the repaired pads look like the original intact pads. After repairing, please measure with multimeter to make sure each pad is successfully repaired.<\/p>\n\n\n\n Next, we introduce another type of pads repair. Scrape to show the circuits connecting the missing pads with Sculpture Knife blade 11. Apply some middle-temperature Solder Paste and heat with Hot Air Gun at 340 \u00b0C to apply tin.<\/p>\n\n\n\n Clean with PCB Cleaner and apply some Solder Mask evenly on the missing pads. Align the pads and remove the excess part.<\/p>\n\n\n\n Solidify with UV Lamp for 5 minutes and apply some Paste Flux. Solder the wires with Soldering Iron<\/a> at 365 \u00b0C. Clean the pads with PCB Cleaner. Apply some Solder Mask again. Solidify with UV Lamp for 5 minutes. Scrape away excess solder mask with Sculpture Knife blade 11. The missing pads have been perfectly repaired.<\/p>\n\n\n\n The above repair shows us that REFOX soldering lug is different from the jumping wire. REFOX soldering lug not only avoids the complex operation of curling wires but also makes the repaired pads look like the original good one. You can now purchase the REFOX soldering lug<\/a> on REWA shop. For more details, please contact our customer service team. What do you think of the REFOX soldering lug?
