Wire wrap is an electronic assembly technique that creates electrical connections by wrapping insulated copper wire around terminal posts. This method ensures gas-tight connections with high mechanical strength and electrical conductivity. Despite advancements in surface-mount technology (SMT), wire wrap remains critical in prototyping, repair, and low-volume production due to its reliability and flexibility.
| Type | Functional Characteristics | Application Examples |
|---|---|---|
| Manual Wire Wrap Tools | Handheld devices requiring operator control | Prototyping, field repairs |
| Automatic Wire Wrap Machines | Programmable systems with high-speed wrapping | Mass production, automotive electronics |
| Semi-Automatic Tools | Combination of manual control and automated wrapping | Custom cable assemblies |
| Wire Wrap Removal Tools | Specialized devices for de-solderless wire removal | Maintenance, design iterations |
Typical wire wrap tools consist of: - Handle/Ergonomic Housing: Provides grip and houses internal mechanisms - Wrapping Head: Contains precision gears and collets for wire control - Wire Cutter: Integrated mechanism for precise wire length control - Motor/Manual Drive: Either electric motor (automatic) or manual trigger system - Control Interface: For programmable parameters in automated systems
| Parameter | Importance | Typical Range |
|---|---|---|
| Wrapping Speed | Directly affects production efficiency | 50-500 wraps/min (automatic) |
| Wire Diameter Range | Determines application versatility | 0.1-1.0 mm |
