Have you ever thought of electronic products beyond their application? How are they made, and what does it take to manufacture such complex equipment with utmost precision?
Well, just like manufacturing pharmaceutical products requires a clean, sterile environment, electronic production units also need sterile conditions that include protection from electrostatic discharge (ESD). Although ESD is one of the most overlooked hazards in electronic cleanrooms, it is the source of compromised product quality and product recalls. This makes ESD protection a crucial function of a cleanroom in an electronic manufacturing unit.
What is Electrostatic Discharge (ESD)?
Electrostatic discharge is the sudden transfer of static electricity between two objects with different electrical potentials. Though these tiny sparks are imperceptible to humans, they are powerful enough to damage electronic components and contaminate controlled environments.
How Are Static Charges Generated?
Walking across floors, handling plastic materials, removing protective packaging, or even friction between garments and the human body generates static charges. In dry environments, static charges accumulate more easily because there is less moisture in the air to dissipate the electrical build-up. In the absence of proper grounding or protective clothing, personnel themselves become a significant source of ESD.
Risks Across Critical Industries
The impact of ESD varies depending on the industry but poses challenges in maintaining a sterile cleanroom.
- Pharmaceutical manufacturing: Static discharge attracts airborne particles.
- Laboratories: Sensitive analytical instruments and precision measuring equipment experience inaccurate readings
- Electronics manufacturing: It impacts the precision and functioning of devices, integrated circuits, printed circuit boards, and other high-value electronic components
Impact on Equipment, Products, and Manufacturing Processes
ESD can cause production downtime, product defects, costly rework, reduced product reliability, and significant financial losses. Apart from that, ESD-related contamination and equipment malfunction lead to compliance issues and product recalls.
Why Cleanrooms Require ESD Control Measures
As the name says, cleanrooms are designed to limit contamination. While these controlled environments are created to maintain a sterile environment, personnel movement is one of the major contributors to contamination. Cleanrooms are aimed at controlling airborne particles, temperature, humidity, and personnel movement but low humidity often results in static charge accumulation. ESD can be effectively controlled by installing grounded workstations, conductive flooring, ionization systems. Beyond all these infrastructural incorporations, ESD safe garments for the personnel forms plays an important role in contamination control in cleanroom.
The Role of ESD Garments
ESD garments are specifically engineered using conductive fibres woven into high-performance fabrics. These garments don’t let the static charges to accumulate on the wearer, instead it is dissipated to the ground. Also, such garments reduce particle shedding from the personnel making them ideal for cleanroom environments.
The Importance of a Complete ESD Garment System
The ESD protection extends beyond wearing an ESD coat or coverall. An effective ESD is a combination of coveralls or lab coats, conductive footwear, gloves, head covers, and face masks. Together, these components provide continuous grounding and protection against electrostatic charge generation.
