CONTROL BOARDS • PCBs • BOARD-LEVEL REPAIR
Defective circuit boards, control boards and printed circuit boards in industrial plants quickly lead to machine downtime, production losses and high consequential costs. Often it is not the entire machine that is defective, but a single electronic assembly, a damaged component, a cold solder joint, a faulty relay, a capacitor, a conductor track or a control board within the system. Retrofit GmbH handles circuit board repair, technical fault analysis, the repair of electronic assemblies and the replacement of defective components. Where an assembly cannot be repaired economically, we support you with the procurement of suitable replacement boards. Our goal is to reduce downtime, minimise production losses and avoid costly new purchases wherever possible.
Maximum performance, minimum downtime
In many production facilities, machines operate reliably for many years. These systems often remain mechanically efficient while individual electronic components fail. A new original circuit board, however, is not always readily available. In some cases control boards, printed circuit boards or machine boards are already discontinued, difficult to obtain or expensive. We have summarised the risks around discontinued components in industry and how to avoid buying the wrong part in a separate article. Professional circuit board repair helps keep existing systems running and avoids costly modifications. Retrofit GmbH tests defective circuit boards independently of the manufacturer.
Test, don't guess
A professional circuit board fault analysis is the first step towards a reliable solution. The goal is to isolate the defect technically and determine whether a repair is possible, economically viable and suitable for continued system operation. When you have a circuit board tested, we always consider the defective assembly in the technical context of the machine, because faults often originate from peripheral components and reappear after a component swap alone.
Targeted component replacement of circuit boards such as relays, capacitors, ICs, transistors, resistors and replacement of electronic components.
Repair of cold solder joints by resoldering, as well as precise conductor track repair in case of thermal breaks or interruptions.
Gentle circuit board cleaning using ultrasound to remove dust, oxidation and repair moisture damage.
Control board and PCB repair
We repair control boards from machine tools, production lines and special-purpose machinery. Where the assembly belongs to a higher-level controller, we test it together with the repair of the PLC control system, because fault patterns frequently originate in the periphery and reappear after a component swap alone.
Whether a printed circuit board can be repaired depends on the condition of the substrate. Individual broken conductor tracks can usually be saved; a board that is extensively charred or delaminated cannot. In that case PCB replication is the alternative, rebuilding the assembly to the same function.
Circuit board repair for older machines and the repair of printed circuit boards for existing systems offer a manufacturer-neutral way to keep industrial electronics and production systems running cost-effectively. This applies beyond the control electronics: boards from operator panels are handled as part of HMI panel repair, mainboards from control computers as part of industrial PC repair. Our references from industry show how this looks in real projects.
A structured process ensures that your defective circuit board is tested and repaired quickly, professionally and manufacturer-neutrally, to minimise downtime.
SUBMIT AN INQUIRY
You send us information about the defective circuit board, photos, nameplates, error messages and machine details.
INITIAL ESTIMATE
Based on your information, we will check whether sending the item in for a detailed repair assessment or an exchange solution makes sense.
DIAGNOSIS AND TESTING
The circuit board is examined in the laboratory: components, solder joints, conductor tracks, connectors and overvoltage damage are analyzed.
REPAIR & FUNCTIONAL TESTING
Replacement of defective components, repair of conductor tracks and subsequent functional and final testing of the circuit board using metrological methods.
Key information at a glance
Circuit board repair refers to the technical testing, fault analysis, and repair of defective printed circuit boards, control boards, or electronic assemblies. This can include component testing, component replacement, resoldering, trace repair, or cleaning.
Circuit board repair is often worthwhile if the board is hard to find, expensive, or discontinued. Especially with older machines and existing systems, a repair can be more economical than purchasing a new one or upgrading.
Depending on the type of damage, control boards, circuit boards, industrial boards, machine boards, power supply boards, power boards, relay boards, communication boards, HMI boards or industrial PC mainboards can be tested and repaired.
Common causes include thermal stress, aging, moisture, corrosion, overvoltage, defective components, damaged conductor tracks, cold solder joints, vibrations or mechanical damage.
Depending on the condition of the circuit board, cold solder joints can be inspected and repaired. Whether this is possible and advisable depends on the type of damage and the assembly.
Depending on the extent of the damage, a circuit trace repair may be possible. It must then be verified whether the electrical function can be reliably restored.
When circuit boards are charred or burned out, it’s necessary to assess the extent of the damage to the board and surrounding components. In some cases, repair is possible; in others, replacement is more practical.
Depending on the assembly and technical capabilities, a functional test or a final inspection of the circuit boards can be performed. Specific testing options depend on the device and the application.
Retrofit GmbH operates independently of manufacturers. The focus is on finding the right technical and economic solution for your system.

Costs depend on the damage and the testing effort involved. The main factors are the effort required to locate the fault, the availability of the components needed, the extent of the repair and the amount of testing carried out afterwards. Replacing a single component sits well below an extensive conductor track repair. After diagnosis you receive an assessment of effort and cost before the repair begins.
