How do you fix a lifted pad on a circuit board?
Repairing a Lifted Pad It may not be pretty, but a lifted pad can usually be repaired. The simplest repair is to fold the lead over to a still-attached copper trace and solder it as shown to the left. If your board has a solder-mask, you will need to carefully scrape off enough to expose the bare copper.

How to remove a broken pad?
If it doesn’t come, continue to apply heat for a few more seconds and then try again. If a pad has been damaged by heat, it’s best to use a sharp knife to carefully remove it.
Does copper tape melt?
Here are a few tips and warnings about this part of the process: Copper tape melts quickly at soldering temperatures , so don’t begin until you’re certain that you can finish this part of the process in one go. Use as little heat as possible and work deliberately, but quickly, to reduce the amount of heat applied. 5.
What is solder pad?
A solder pad is the part of a printed circuit board — or PCB — that supports the pins of components like transistors and chips. Typically, when devices break or components are removed from PCBs, it can result in damaged and missing solder pads.
Can you use open air to cure a lap joint?
You can either use open air to cure it, or you can use an oven — but be sure to follow all manufacturer guidelines. Soldering the new pad/trace to the conductor: Use Kapton tape to place and hold the replacement pad. Use the appropriate solder alloy to make a lap joint.
Step 1: Cleaning
Clean the damaged are with isopropyl alcohol and blow dry with canned or compressed air or damp dry with a lint free cloth.
Step 5: Clean
Clean the area using isopropyl alcohol and dry via compressed or canned air or a lint free cloth.
Step 6: Tin the Conductor
Using the correct type of solder alloy tin the conductor area in place where the new conductor will be attached
Step 7: Sise Up and Select the Right Circuit Frame
Select the new conductor from the circuit frame. Cut out with sharp small knife.
Step 10: Clamp and Cure
Hold the replacement pad/trace in place until cured. Remove the clamp. Clean with isopropyl alcohol and inspect. I also like to perform a quick electrical continuity check at this point. In some cases I even envelope the edges of the replacement pad/trace with solder mask or epoxy and cure so that it has extra mechanical strength.
