Static Electricity Prevention: Making Electronic Component Production Lines Fearless
Static electricity can damage certain electronic components. Electrostatic discharge (ESD) causes economic losses of tens of billions of dollars annually. Implementing and maintaining ESD control programs can prevent ESD damage to today's increasingly sensitive electrical or electronic components, assemblies, and equipment, improve overall process performance and product control, reduce failure rates, minimize rework, save costs, create a competitive advantage, and enhance market competitiveness.
Simply put, ESD control is related to electronic components on the production line. Taking effective measures can save costs, reduce the problems of low product yield and high failure rates caused by ESD damage to sensitive components, and improve product quality. The main difficulty in controlling ESD is that it is invisible yet can still damage electronic components. A discharge that can be heard with a "crackling" requires the accumulation of a relatively large charge of approximately 2000 volts, while 3000 volts can be felt as a small shock, and 5000 volts can be seen as a spark.
Therefore, as a major source of ESD hazards, all personnel entering the ESD protection area for electronic component production must take safety precautions to prevent any charge accumulation and ESD discharge.
The primary product used to prevent ESD (Electrostatic Discharge) is the wristband. An ESD wristband is a device worn on the wrist to discharge accumulated static electricity from the body. It comes in wired and wireless types, featuring a combination of metal rings and elastic conductive wire loops. The spring-loaded grounding wire can withstand over 30,000 wrapping tests without breaking. The wired ESD wristband's adjustable buckle effectively protects zero-resistance components from static interference and discharges static electricity from the body. The inner layer of the elastic band is woven with anti-static yarn, while the outer layer is woven with ordinary yarn. The principle of the ESD wristband is to conduct static electricity from the body to the ground through the wristband and grounding wire. During use, the wristband must be in contact with the skin, and the grounding wire must be directly grounded to achieve maximum effectiveness.
In addition, personnel entering the electrostatic discharge (ESD) protected area must wear anti-static clothing and shoes, and corresponding protective measures should be formulated according to the anti-static level required by the product. In short, ESD is a systematic project, from anti-static grounding, anti-static flooring, anti-static workbenches, anti-static work clothes, anti-static gloves, anti-static wrist straps, anti-static shoes and other protective products to EPA area division, monitoring, training and other projects, all of which require professional ESD engineers and managers to establish and maintain.
