Welcome to BestESD Technical Services – leading ESD/EMI/EOS specialists for the global electronics industry! If you ended up here, most likely you are looking for a solution to a problem with ESD, electrical overstress (EOS) or EMI.  You came to the right place.

ESD, EOS and EMI issues facing us in design, manufacturing and use on grow more challenging every year. Component sensitivity to ESD and electrical overstress (EOS) are on the rise, and EMI susceptibility in the process is becoming more critical. Planning, building and maintaining a safe and manageable ESD/EOS/EMI environment is not only increasingly important, but requires more specialized expertise than ever before. 

BestESD provides professional problem-solving and technical guidance for every ESD/EOS/EMI consideration in design and production today – from electromagnetic compliance of emerging products, to resolving interference and immunity issues in challenging production facilities, to ensuring a safe ESD and EOS environment for sensitive components and assemblies. 

Electrical Overstress (EOS)

"EOS is the number one source of damage to IC components" according to Intel*. Industry standards as IPC-A-610 set acceptable voltage levels for sensitive components to no more than 0.3V peak. ​

Perhaps the most damaging aspect of EOS is that often the damage is "latent," i.e. when the device or the board which is "wounded," not outright "killed" by excessive voltages and currents, passes the test, but then fails in actual use due to the weakened internal structure. Not only this adds to the cost and aggravates customer relations, it also threatens applications where a "failure is not an option."

Electromagnetic Interference (EMI)

Electromagnetic interference (EMI), or  unwanted high-frequency signals, are common in almost any environment, especially where there are plenty of noise-generating equipment. EMI manifests itself in a number of ways:

  • Outright equipment lock-up

  • Tools do things they weren’t supposed to do

  • Software errors

  • Erratic response

  • Parametric errors

  • Measurement inaccuracy and lack of repeatability

  • Component damage

All of that causes equipment downtime, loss of productivity and product defects.

Electrostatic discharge (ESD) is one of the key factors impacting quality, reliability and yield in electronics manufacturing. Increasingly sensitive circuits mean that even the best-engineered process can and will produce serious, avoidable defects if proper ESD management is overlooked.

ESD is not merely an internal issue- it’s a critical component of business relationships. Ties between suppliers and customers are often strained by defective parts, and electronics manufacturers are facing stronger pressure to ensure consistency and quality.
