ESD: The difference between reliable repair and latent failure
A spark you cannot see, feel or hear. That is the most treacherous enemy of modern electronics: Electrostatic Discharge (ESD). In a sensitive component, a discharge of just 30 volts can be enough to degrade or destroy it, and the human body does not even perceive it until it exceeds 3,500 volts.
At Comter México, we know that the real risk of ESD is not immediate catastrophic failure, but latent failure: the component that is "wounded" and months later, already on your production line, stops working without apparent explanation. That is why our commitment to ESD control is absolute. It is not an option; it is the foundation of the reliability we offer to partners like Molex, Flex and Sanmina.
ESD control in every repair
A controlled environment. No exceptions.
Protected work area (EPA)
Our entire repair workshop is configured as an EPA. Tables, floors, workstations and storage shelves are connected to a common ground point, creating a "zone zero" where potential differences simply do not exist.
Universal ground connection
We have a dedicated and verified ground network. Each workstation has multiple connection points for wristbands, and all equipment (soldering irons, magnifiers, testers) is properly grounded. We periodically measure the resistance of these points.
ESD-safe tools and consumables
We do not use conventional tools. Everything that touches a board in our facilities is ESD-safe: dissipative-coated tweezers, grounded soldering tips, dissipative mats, and metallized or anti-static storage and shipping bags.
Staff discipline
Every technician is trained in handling sensitive components and uses their anti-static wristband connected to ground daily. Before starting any repair, the connection is verified. It is a non-negotiable habit.
Our EPA in action
In our facilities, the protected work area is not a concept—it is a reality. Floors, tables and stations are connected to a common ground point, creating the safe zone that every repair demands.
Every station, connected
Each workstation has connection points for wristbands and equipment. Periodic measurements ensure that ground resistance is correct at all times.
Tools and discipline
ESD-safe soldering irons, tweezers and consumables, plus the routine of verifying connection before each repair. This is the standard we work with for you.
What does latent failure mean for you?
Know the difference.
Without ESD control
When you trust the repair of a critical control to a workshop that does not control ESD, you are assuming a risk you cannot see. A component damaged by a discharge may pass all immediate functional tests, but its useful life will be drastically reduced. The "repaired" unit could fail at the worst moment, in your plant, stopping your production.
With Comter México
We eliminate that risk. When you receive a unit repaired by us, you have the guarantee that it has been handled in an environment that protects its long-term integrity. It is not a promise; it is our operating standard.
Our ESD control has backing
Our ESD control program follows international standards such as ANSI/ESD S20.20 and recommended practices for handling sensitive components. Combined with our ISO 9001:2015 certification, we ensure that every repair leaving our hands has been treated with the same rigor as on the production lines of our most demanding clients.
At Comter México, the invisible is controlled. Your equipment is protected.
