How to Repair a Broken Printed Circuit Board
- Mix the epoxy according to the manufacturer's instructions, and apply it sparingly to one side of the PCB.
- Cut through the broken copper traces using a razor knife. ...
- Plug the soldering pencil into a 110-volt receptacle and wait for it to get hot. Clean the hot soldering tip by wiping it on a wet soldering sponge.
- Apply a fresh "tinning" coat of rosin-core solder to the clean soldering pencil tip. A properly tinned tip will be a bright silvery color.
- Apply the rosin-core solder to the bared copper traces on the printed circuit board. Use care to apply no more heat than is necessary to melt the solder.
- Cut pieces of the 18-gauge copper wire that are long enough to span the cut traces, and tin these short lengths of wire with rosin-core solder.
- Pick up a piece of tinned wire with the tweezers and lay it carefully across one of the traces where you removed a loose section.
- Reassemble the device and test it to see if it works properly. ...

What is trace in PCB?
A PCB trace or PCB track is a copper conductor on the PCB that conducts signals on the surface of the PCB. It is the flat, narrow portion of the copper foil that is left behind after etching. The electricity that flows through the copper traces generates a significant amount of heat.
How do you fix a fried circuit board?
To actually get it off the board you can heat up each lead one at a time and use the solder sucker to get the majority of the solder away, then gently (Very gently) pry up on that lead you've melted and sucked away the solder on, and allow it to cool while you're holding it away from the board.
What is PCB trace?
First things first, let us introduce you to PCB trace. In a nutshell, it is a network of different parts and pieces that make a printed circuit board. Some of these are wires, insulation, copper, fuses, etc. Now, each of these parts can malfunction, so figuring out what the problem is can take a lot of time.
Know the board
Before you even start working on solving the problem, you need to get familiar with the printed circuit board down to the last detail. First of all, you need to know all the parts and pieces that it includes. Secondly, you need to explore their dimensions.
Is the repair necessary?
Even though we said that a trace on a printed circuit board could be fixed, it still doesn’t mean that there aren’t some instances when you should just go and purchase a new one. What are some tell-tale signs that the PCB can still serve you?
How to fix it?
Naturally, the first thing you can do is locate the damage. Unless you know exactly what you are doing, this may take some time. If you want to be more efficient, you should read more about circuit traces to get the knowledge you need to proceed. Once you have managed to do this, you need to remove the green coat from the damaged trace.
Things to consider
Now that we have introduced you to two different techniques you can use to repair a trance on a printed circuit board, we have to tell you about some additional things. Firstly, and most importantly, you have to be careful with the electricity when testing the board.
Wrapping up
Considering that a printed circuit board is an essential part of every device and also that it can be easily damaged, this short guide should help you deal with the issues. As you can see, there are two techniques and different tools you can use. However, you have to analyze the problem thoroughly to understand which method is appropriate.
How to fix a broken PCB?
Step 1. Mix the epoxy according to the manufacturer's instructions, and apply it sparingly to one side of the PCB. Press the two halves of the broken board together, and hold them until the epoxy takes hold. The epoxy will set in a few seconds, but you should wait for thirty minutes before proceeding to the next step.
How to tell if a traces is broken?
The easiest way to identify broken traces is to use a digital multimeter and take readings between adjacent terminal points on the board. Simply set the multimeter to the "Ohms" function and touch the probes to the traces. A bad trace will show as an "O.L." on the multimeter. A good trace will read 0.00 to 0.5.
How to clean a soldering pencil?
Plug the soldering pencil into a 110-volt receptacle and wait for it to get hot. Clean the hot soldering tip by wiping it on a wet soldering sponge. Make sure to remove all the dirt and oxidation from the tip.
How to remove copper traces from a sanded sandpaper?
Cut through the broken copper traces using a razor knife. Remove all of the loose traces, and then carefully use the emery cloth to sand the traces from which you removed the loose sections. Sand the ends of these traces until the bright copper shows clearly.
How to fuses copper wire?
Pick up a piece of tinned wire with the tweezers and lay it carefully across one of the traces where you removed a loose section. With the piece of wire lying across the gap, touch the soldering pencil's tip to the top of the wire until it fuses to a copper trace on the board. Repeat this step with the remaining wires.
What is a low wattage soldering pencil?
A low-wattage soldering pencil is an important tool for repairing broken PCBs.
How to check if a solder connection is faulty?
if the device doesn't function as it should, check your repair job by taking meter readings from the next point on the circuit breaker on each side of the repair. This will show any faulty solder connections.
How to get solder resist off PCB?
Scrape a little of the solder resist off with a knife, sharp screwdriver or fine sandpaper. Ensure that the exposed track is clean and shiny. It is also a good idea to clean any residual burnt PCB material off, to allow the tape to stick well.
What happens if a PCB is overheated?
If a PCB is overheated the most likely outcome is that the copper layer will de-laminate from the fibreglass board. This usually leads to broken joints and a non-working circuit. It is possible to repair some faults using adhesive copper tape and solder. Ask Question.
What is a PCB made of?
Printed Circuit Boards (PCB) are made from layers of fibreglass and copper, glued together. Whilst the glues used are very heat resistant it is possible to overheat a PCB and damage it. Kitronik PCB designs use large tracks and pads to help make this a rare problem, the larger amount of copper helps to dissipate the heat.
Can copper tape be cut?
The Copper tape can be cut to size with scissors, craft knife etc. Once a repair has been made it is also possible to trim the excess tape. If this is done exercise caution, as the repair is more fragile than the original PCB track, and may become unstuck again.
Does copper tape melt?
Carefully solder the joint (s) where the repair has taken place. Most copper tape adhesive melts at soldering temperatures, so be quick and use as little heat as possible. When the tape cools the adhesive will usually remain sticky.
