The SW-836D is a small flexible tip foam cleanroom swab with a soft polyurethane foam head engineered specifically for cleaning applications where contact surfaces are irregular, recessed, or fragile enough to be damaged by a rigid swab tip. The defining feature of this model is the flex tip configuration — the foam head is constructed to bend under light pressure and return to its original profile, allowing it to conform to curved surfaces, slot interiors, and component contours without applying concentrated mechanical stress.
The swab head measures 12mm in length, 3.6mm in width, and 3.2mm in thickness. The flexible polyurethane foam material delivers high absorbency while maintaining a lint-free, low-particle-generation surface in contact with the substrate. IPA compatibility and solvent resistance make this swab suitable for standard wet-cleaning procedures used in semiconductor packaging, PCB rework, and optical component preparation.
The flex tip design differentiates the SW-836D from standard pointed or rectangular head swabs in scenarios where cleaning inside curved housings, around component leads, or within cylindrical channels is required. The foam compresses and rebounds rather than dragging across delicate bond structures or coated surfaces, reducing the risk of surface damage during the cleaning pass.
Low NVR characteristics ensure that solvent residues do not remain on cleaned substrates after evaporation, which is critical for processes requiring low ionic contamination levels, such as wafer-level packaging and optical fiber splicing preparation.
The polypropylene handle measures 72mm in total length with 2.8mm width and thickness, optimized for precise manual control in tight working areas. Industries served include semiconductor manufacturing, PCB manufacturing, optical cleaning, precision electronics, medical device production, and laboratory cleaning. Use cases include hard-to-reach area cleaning, optical lens cleaning, sensor cleaning, and precision instrument maintenance. Packages are available in 100-piece small packs and 500-piece large packs.
