Operations and dispatch? Operations: Wear anti-static wrist straps (during assembly), ensure the workbench is earthed; Dispatch: Anti-static bags + cushioning + outer carton. Operational standards must comply with ESD standards.
Static electricity is the ‘invisible killer’ of electronic products: invisible to the naked eye, it can damage a chip with the mere movement of a hand — hence, no room for complacency when selecting materials or labelling for ESD-protected packaging. This article clearly explains the key aspects of ESD protection; clients involved in electronic packaging may refer to it as required.
How to select anti-static bags? Anti-static bags (shielding bags / mesh bags): shielding (protection against external static electricity) and dissipation (prevention of static build-up); the ‘surface resistance’ (specification) must be verified against standards. The selection of anti-static bags should be based on the principle of ‘shielding + dissipation’.
How to use mesh bags? Mesh bags (anti-static bubble wrap): cushioning + anti-static protection, suitable for ‘fragile electronic components’; ‘opening and sealing’ (sealing) provides protection against moisture and dust. The specific requirements for mesh bags should be determined by the product’s risk profile.
How should labelling be carried out? ESD labelling (ESD symbols): ‘Anti-static’ (warning) should be printed on the bag surface; ‘Do not touch with bare hands’ (operational instruction) should also be printed. The key principle for labelling is that it must be ‘visible and legible’.
First, identify what needs protection. The scope of electrostatic protection includes: anti-static bags (packaging materials), earthing (operating environment) and labelling (warnings). Determine whether the ‘product is sensitive to static electricity’ (chips, motherboards) or the ‘environment requires anti-static measures’ (workshops, warehouses) before finalising a plan. — Packaging protects against handling; the environment protects against accumulation.
The economics of electrostatic protection: anti-static bags provide shielding, mesh bags provide cushioning, and labelling establishes standards — by clearly understanding ‘what the product is vulnerable to’, expenditure on electrostatic protection is directed to the critical areas.
