Test unit controls access to ESD protected areas

25 September 2019 Circuit & System Protection

In the electronics manufacturing industry, an electrostatic discharge (ESD) can cause irreparable damage to electronic components. This micro-lightning bolt can burn holes through insulating layers and metal of microcircuits, causing it to malfunction. A discharge as miniscule as 60 V can destroy electrical components and negatively impact revenue streams.

An electrostatic protected area (EPA) is the designated space where no items or activity are able to cause ESD damage. The EPA consists of a grounding ecosystem where various conductive and dissipative materials and components work together to control static charge build-up. These components include wrist straps, grounding cords, dissipative flooring, ESD clothing and footwear, as well as testing equipment.

The SmartLog Pro is a static access control and testing unit that verifies the functionality of an operator’s grounding devices to ensure it is functional and compliant before entering the EPA. If the operator fails the static compliancy test, SmartLog will not allow access into the EPA.

“This is a next-level access control unit. It not only provides ESD testing, but offers time management of personnel as well. It makes auditing much easier. It is easy to install and can form part of a turnstile, sliding door, or function as a standalone item. SmartLog can operate on biometrics and a card system with adjustable settings for different people who need to access the EPA,” explains Actum Group ESD specialist, Nick Sibanda.

This testing unit features a five-inch colour touchscreen with an intuitive user interface for easy test operation and a clear indication of test results. The operator average test time is only two seconds. It can generate and e-mail automated reports to track short-term and long-term corrective actions.
