Resistance Testing Methods for Semiconductor Cleanroom Gloves: A Practical Guide
Based on ANSI/ESD SP15.1-2011, this article explains the complete resistance testing method for semiconductor cleanroom gloves: the distinction between intrinsic material resistance and in-use resistance, the required equipment, environmental and sample requirements, the operating steps for the bare-hand baseline and three voltage levels, result interpretation ranges, and common pitfalls. It can be applied directly to on-site acceptance and incoming inspection.

Application Value of Cleanroom Mops in Pharma Industry
Pharmaceutical cleanrooms shall comply with GMP requirements to control particulate matter and microorganisms. Traditional cotton mops tend to shed fibers and harbour bacteria, which carry risks of product contamination and non-compliance during audits. Medical-grade cleanroom mops are made of continuous filament polyester / microfiber with ultrasonic edge-sealing technology. They feature low particle generation, resistance to a wide range of disinfectants, sterilizability and strong particle adsorption, suitable for GMP Grade A/B/C/D cleanrooms, microbiology laboratories and other areas. Disposable sterile mop heads are selected for Grade A/B zones, while re-sterilizable types are adopted for Grade C/D zones. Colour-coded zone management can reduce product rejection and the risk of out-of-specification environmental monitoring. Complete supporting validation documents facilitate incorporation into SOPs to meet drug regulatory inspections. Selection based on cleanroom classification, proper storage and periodic testing are required in use. Such mops serve as critical cleaning consumables for pharmaceutical manufacturers to control cleanroom environments, ensure drug quality and maintain GMP compliance.

AMEC Chairman Yin Zhiyao: Equipment is the "lifeline" of the semiconductor industry — AMEC responds to industry consolidation with a platform-based strategy.
"Chip design and manufacturing sit at the head of the industrial chain, driven by end-user applications. Semiconductor equipment, by contrast, is the very foundation of the industry, extending downward to components and materials. For a nation's semiconductor development, equipment, components, and materials are the chokepoint," Yin Zhiyao said.
