Are you looking for reliable and professional printed circuit board repair services? As a leading pcb manufacturer, Huaxing understands the importance of these boards to your business. From consumer electronics to advanced industrial systems, PCBs are at the heart of modern electronic devices. However, even the best-designed and manufactured boards can fail. Failure may occur as the result of use, or it may result from an electrical overload or aging components. Our printed circuit board repair services will help you reduce costs while increasing your ability to return your board to service.
When a printed circuit board fails, it will affect not only your product but also your workflow and productivity.
Often the decision comes down to whether you’ll repair boards or replace them. In most cases, it’s cheaper and faster to repair the board in question.
The research shows that printed circuit board repair is a far better decision in most cases than board replacement. It is true that not all PCBs are repairable. If the components on the board are beyond repair, you will need a replacement. But a leading PCB repair company like Mermar Electronics will always investigate all board repair options completely prior to coming to that conclusion. There are several reasons that PCB repair is a better decision than replacement:the increased complexity of current boards;the ability to use specialized equipment and tools to repair boards; andthe cost of staffing to repair and replace boards.
Ultimately, there will be situations where replacement is the best or only option, but the research we have been able to locate shows that printed circuit board repairs will often save 50 to 75% of the costs associated with replacement with a new board. This is a significant impact to your profitability in the long run.
Cost Savings: Repairing PCBs is always cheaper than replacing them, particularly for specialized or custom boards.
Reduced Downtime: Fast repairs mean your business can get back to normal more quickly without having to wait weeks for a replacement board.
Environmental Responsibility: By repairing instead of discarding, you are also contributing to reducing electronic waste—a win-win for both the company and the environment.
Understanding why PCBs fail is key to effective repairs. Below are some common issues we handle:
Over time, components like capacitors or resistors can degrade or fail due to electrical overload. For instance, electrolytic capacitors often dry out over time, leading to failure.
Traces are the copper pathways on PCBs that connect various components. Traces can break due to stress or corrosion, often leading to interrupted connections that make the board inoperative.
Dust, moisture, or extreme temperatures can damage the board. Moisture is particularly common and can lead to trace corrosion or component failure.
Voltage surges or excessive current can burn components or traces, often caused by power supply issues or unexpected usage conditions.
For a PCB repair company to be reliable, the shop must possess the tools to perform the necessary repair services and do them competently. You expect all functions of your PCB to work after a repair. You can’t always assume this because there are different levels of PCB repair services available. A leading board repair company like Mermar Electronics uses the appropriate tools to repair, replace, or rework your printed circuit boards. It means that the technicians have the training and knowledge to repair the problems you’re experiencing.
Tools you may need include:
soldering and desoldering stations;hot air rework stations;multimeters and oscilloscopes;rework stations for BGA devices; and microscope inspection systems.
Each of these tools and techniques impacts specific printed circuit board designs and problems you’ll encounter. Let’s talk about a few of these issues and the tools necessary to correct them.
Soldering and Desoldering Tools
Soldering and desoldering tools are must-have resources for any PCB repair shop. You must be able to secure new components to the board, and you must be in a position to remove failed parts. It is important to use proper soldering techniques to fix printed circuit boards accurately without causing annoyance to the end-user.
When looking to repair printed circuit boards, you need to ensure that you properly prepare boards. Soldering involves several steps to accomplish the task correctly and with the minimum amount of time. You rely on your sophisticated tools and equipment, but to prepare the board correctly, you must carefully follow the process required to install each component piece properly. Again, this preparation and precision are why you need a company that knows what it’s doing. You’re not trying to repair boards so that things sort of
work. You want all functions restored after board repair, and you want them to stay that way. As a manufacturer, you and your customers demand systems work correctly. Otherwise, a poor track record can result in terminations and lost contracts, which have a significant impact on your bottom line and business viability.
Here is our approach to efficient board repair:
1.Locate and identify the faulty component.
2.Select the appropriate removal method based upon the lead configuration.
3.Remove the defective part.
4.Select the replacement device.
5.Replace the component.
6.Verify operation.
It sounds simple, and if you have a standard mass-produced board with 1980s-era technology, it is. But as you know, those boards aren’t what we deal with now. Today, you find highly complex circuits with hundreds of minutesized components packed onto the circuit board.
Below is a comparison of how we help you decide between repairing or replacing a PCB:
| Attribute | Repair | Replacement |
| Cost | Lower, especially for custom or complex boards | Higher, especially for specialized boards |
| Downtime | Shorter if parts are available | Longer, especially for custom production |
| Environmental Impact | Positive, reduces e-waste | Negative, more waste generated |
| Complexity | Requires skilled technicians | Relatively simple but requires production setup |
In most cases, repair is the wiser choice—saving costs, reducing downtime, and minimizing waste. However, skilled technicians are key, which is why our Huaxing team is committed to providing professional repair solutions.
If the cost of replacing a PCB exceeds the cost of repair, repair is usually the best option. This is particularly true for older or custom boards, where replacement costs can be very high.
For custom or obsolete boards, repair is often the only viable solution since manufacturing a new custom PCB is both time-consuming and expensive.
When time is critical, repair is the fastest option—especially when replacement boards are not easily available. Our fast, professional repairs can restore your system's operation without long delays.
Huaxing provides professional PCB repair service to get your application back in service without all the drama. The question often arises about how you can incorporate this into your existing board fabrication activities. It’s not difficult to do if you have a partner willing to help you. Many companies are happy to work with you when you want to purchase boards from them, but if something goes wrong, you fight them for support. That’s not good. You need a provider that helps solve problems. That’s one of the differentiators for Huaxing. We love to work with you. We appreciate our customers, and we do everything possible to help you succeed. It goes beyond haggling over price.
The selection and uses for printed circuit boards will continue to increase.
Demand for PCBs will expand tremendously as environments like Artificial Intelligence (AI), the Internet of Things (IoT), Industry 4.0, and wireless technology continue growing at geometric expansion rates. Your business needs a PCB supplier with vast board manufacturing capabilities. While many board companies exist, Huaxing is a leading PCB manufacturer that provides an enormous selection of all types of PCBs. Huaxing works with customers to design, build, manufacture, deliver, and repair quality, high-performance printed circuit boards. Because we are in a competitive world, our board manufacturer always seeks to provide the highest quality products, services, and value proposition for your business.
