Tweezers

1. Overview

Tweezers are precision handheld tools designed to grasp, hold, or manipulate small objects inaccessible to human fingers. Modern tweezers integrate advanced materials and ergonomic designs to meet demands in electronics, healthcare, laboratory research, and industrial manufacturing. Their importance lies in enabling precise handling of components at micro and nano scales, critical for semiconductor assembly, surgical procedures, and material science applications.

2. Main Types and Functional Classification

Type	Functional Features	Application Examples
Anti-Static Tweezers	Conductive carbon fiber composite, ESD protection	PCB assembly, IC handling
Carbide-Tipped Tweezers	Hardened tungsten carbide tips, wear-resistant	Automotive sensor manufacturing
Smooth Tip Tweezers	Polished stainless steel, non-marking grip	Optical lens alignment
Spring-Loaded Tweezers	Automatic opening mechanism, fatigue reduction	Micro-surgery procedures
High-Temperature Tweezers	Chrome-cobalt alloy, 1200 C resistance	Metallurgical sample handling

3. Structure and Components

Typical construction includes:

Jaws: Angled or straight tips with precision-ground surfaces
Shaft: Hollow or solid design with length ranging 75-150mm
Material: Medical-grade stainless steel, titanium alloys, or polymer composites
Surface Treatment: Electropolishing, diamond-like carbon coating
Ergonomic Features: Bi-material handles, textured gripping zones

4. Key Technical Specifications

Parameter	Importance
Tip Hardness (HV0.1): 550-1800	Determines wear resistance and longevity
Parallelism Tolerance: 5 m	Ensures uniform gripping force
Thermal Stability: -196 C to 1200 C	Enables extreme environment operation
Surface Roughness (Ra): 0.05 m	Prevents particle contamination
Spring Force: 0.5-5.0N	Optimizes handling precision

5. Application Fields

Key industries include:

Electronics Manufacturing: SMT component placement, BGA rework
Medical Devices: Stent assembly, ophthalmic instrument calibration
Life Sciences: Cell manipulation, histology sample handling
Aerospace: Composite material repair, avionics maintenance
Photonics: Fiber optic alignment, laser component assembly

6. Leading Manufacturers and Products
