Control engineering: We diagnose, repair, guarantee
At the heart of every automated production line lies a critical component: control systems. When they fail, operations stop. At Comter México, we specialize in being the high-level technical resource that reactivates those systems. We don't just repair hardware—we understand the logic, software and interconnection that make it work.
Our team is trained to the highest industry standards, with years of experience working directly with the specifications of world-class OEMs and EMS such as Molex, Flex and Sanmina. We approach every control as an engineering challenge, not a simple repair.
Control repair
PLCs & industrial controllers
We repair CPUs, power supplies and I/O modules from leading brands (Siemens, Allen-Bradley, Mitsubishi, Omron). We diagnose at component level, including communication port issues.
Variable frequency drives (VFDs)
We restore AC and DC drives. We work on control boards and power stages, identifying and replacing faulty IGBTs, capacitors and gate circuits.
Servo drives & robots
We address the complex electronics of servo drives and robot controllers. We repair encoder boards, feedback circuits and high-precision power stages.
Industrial power supplies
We diagnose and repair switched, linear and industrial UPS. We solve noise, regulation and burned-component issues to restore system reliability.
Motherboards & logic boards
Specialists in custom control board and industrial equipment motherboard repair. We rebuild traces, replace BGA and physically damaged microcontrollers.
HMI interfaces & displays
We repair operator panels, touchscreens and displays. From backlight issues to digitizer or control logic failures.
Our engineering method
For guaranteed results.
Advanced diagnosis
We don't rely on assumptions. We use equipment such as digital oscilloscopes, VI curve analyzers, thermal cameras and high-precision multimeters to locate the fault, even if intermittent.
Precision repair
Our IPC-certified technicians perform the intervention under a microscope, using micro-soldering techniques, BGA reballing and circuit reconstruction, ensuring board integrity.
Post-repair functional test
The most critical step. Whenever possible, we test the repaired control on a simulation bench or, if logistics allow, we validate its operation directly on your equipment before considering it complete.
Beyond repair, we secure your operation
Drastic reduction in downtime (MTTR)
Our fast diagnosis and repair capacity minimize the time your machine is stopped.
Access to critical and obsolete components
We have a supplier network and component warehouse that allows us to source difficult or discontinued parts.
Guaranteed repair
We stand behind our work. Our warranty reflects the confidence we have in our processes and our technicians.
Technical documentation
We deliver reports and traceability so you know exactly what was done and how.
