| ESD swab Descriptions: Purestat® ESD clean swabs are provided with high quality and great cleanliness, and usually used in cleanroom and industry of wafer, display, harddisk driver, pharmacy/boilgical technology, optics/photoelectricity etc. The swab's head is designed elaborately, can remove particle and residuce with out any abrasion. Unique thermal bonding and cleaning process ensure a minimum of particle shedding from swab head. The handle is made from patent inherently dissipative polymer to provide clean and permanent ESD protection without contributing particulate contaiminated to the cleanroom. Features: 1. Compressed, 100 PPI open-cell structure with excellent absorbency; 2. Thermally bonded head; 3. No contamination adhesives; 4. Available for cleaning small slotted and groove areas; 5. No silicone oil, amide, DOP, etc; 6. Low particle generation 7. Low nonvolatile residue 8. Compact ESD-safe handle, permanent ESD protection. Parameters: 1. Nonvolatile Residue Test: IPA extractant ≤0.40 mg/swab DI extractant ≤0.15 mg/swab 2. Ion: chloride ≤ 0.9 μg/tip; sulphate ≤ 0.4 μg/tip; total anion ≤ 1.3 μg/tip. 3. LPC test: particle( ≥0.5μm): <25000 counts/ tip; no silicone oil, DOP, amide ESD characteristics: Handle resistivity: 1×106≤RS≤1×1010Ω Triboelectricity charge voltage: <10 volts Decay time(1000V~50V): <2s Size: | head width | head thickness | head length | handle width | handle thinkness | handle length | total length | Packing | | 3.20mm | 2.00mm | 10.00 mm | 2.40 mm | 2.20 mm | 61.00 mm | 70.00 mm | 100pcs/pack |
