Precision Tweezers
Tweezers
Precision tweezers are hand tools for gripping, positioning and inspecting small components in electronics manufacturing, laboratories and precision engineering. Tip geometry follows the Swiss pattern system (00, 0, 1, 2, 2A, 3, 3C, 4, 5, 5A, 7, 7A, AA, OO, SS, MM), where digit and letter define tip width and bend. ESD versions are dissipative to IEC 61340-5-1 and keep resistance within 10⁶ to 10⁹ Ω, so electrostatic sensitive devices are not damaged during handling. The range covers 550 articles, with Bernstein, Weller, Knipex, Piergiacomi and Lindström as the leading brands.
| Shape | Tip geometry | Typical use |
|---|---|---|
| 00 | medium fine, sturdy | general gripping during assembly |
| 2A | flat round, 2 mm wide | positioning flat components |
| 3C | slim, straight | standard shape for fine assembly |
| 5 | needle fine | wires and miniature parts |
| 7A | curved, fine | work at a viewing angle |
| SS | very slim, extra fine | microscope work on the finest structures |
Typical applications: SMD rework and fault finding under a stereo microscope; placement and repair of printed circuit boards in EPA areas; sample handling in laboratory and analytics; precision mechanics, optics and watchmaking; assembly of stranded wires and connectors; visual and incoming goods inspection of small parts.
