The SW-847B is a rounded polyester tip cleanroom swab designed for precision cleaning in electronics, optical component manufacturing, and medical device production environments. The swab head is constructed from knitted polyester with an open-cell fiber structure that adsorbs and retains particulate matter during wiping, reducing the risk of particle redistribution onto adjacent cleaned surfaces.
The rounded polyester tip measures 17mm in length, 6.8mm in width, and 2.8mm in thickness. The round tip geometry provides a consistent contact profile across both flat and slightly curved surfaces, and the relatively wide head allows efficient coverage of component surfaces without requiring multiple wiping passes. The polyester fabric is lint-free and exhibits low particle generation, maintaining compliance with cleanroom cleanliness requirements during routine use.
The swab head demonstrates strong wear resistance and tear resistance under normal wiping pressures and repeated solvent exposure. Chemical resistance allows compatibility with IPA, acetone, and other common cleaning solvents used in semiconductor assembly and optical surface preparation. The low NVR characteristic of the polyester material ensures minimal chemical deposit remains on substrates after cleaning.
The polypropylene handle is bonded to the polyester head through a hot-press process rather than adhesive bonding, eliminating adhesive-derived ionic contamination as a process risk. Handle dimensions of 100mm total length with 3.2mm width and thickness provide stable control during both dry wiping and solvent-assisted cleaning operations. Antistatic properties of the handle material make the SW-847B suitable for use in electrostatic discharge-sensitive manufacturing zones.
This swab is used in semiconductor industry cleanrooms, optical cleaning processes, PCB manufacturing, precision electronics assembly, pharmaceutical cleanroom operations, and medical device production. Application scenarios include optical lens cleaning, printed circuit board surface preparation, sensor cleaning, and hard-to-reach area cleaning in assembled instrument housings. Each package contains 100 pieces.
