Selecting the wrong type of enameled wire in the manufacturing of electronic transformers and motor windings can reduce production efficiency. This article analyzes the core differences between solderable and non-solderable enameled wires to help you precisely match application scenarios, reduce costs, and improve efficiency.
✅ Solderable Enameled Wire
No scraping required before soldering. The enamel coating automatically decomposes at temperatures above 360°C. Solder flows directly upon contact with the soldering iron.
Representative products: Polyurethane enameled wire, self-soldering enameled wire.
✅ Non-Solderable Enameled Wire
Requires scraping or insulation removal before soldering. The high-temperature-resistant enamel coating does not decompose and requires mechanical/chemical removal for soldering.
Representative products: Polyester enameled wire, polyamide-imide enameled wire, high-temperature-resistant enameled wire.
| Property | Solderable Enameled Wire | Non-Solderable Enameled Wire |
| Soldering Efficiency | ★★★★★ Instant soldering without pretreatment | ★★☆☆☆ Requires additional insulation removal step |
| Temperature Rating | ★★★☆☆ Max 155°C (Class F) | ★★★★★ 180–240°C (Class H/C) |
| Suitable Wire Gauge | ★★★★★ Ideal for ultra-fine wires <0.1mm | ★★★☆☆ Recommended for standard wires >0.1mm |
| Mechanical Strength | ★★★☆☆ Moderate | ★★★★★ Extremely high scratch/abrasion resistance |
| Typical Applications | Electronic transformers / SMD inductors / Drone motors | Industrial motors / New energy vehicle motors / Power transformers |
Suitable scenarios for solderable enameled wire:
✓ Automated production lines
✓ Soldering micro coils (≤0.1mm)
✓ Avoiding wire damage from scraping
✓ Fast-repair scenarios
Suitable scenarios for non-solderable enameled wire:
✓ Operation in 200°C+ high-temperature environments
✓ Strong chemical corrosion resistance required
✓ Ultra-high insulation reliability needed
✓ Cost-sensitive bulk procurement
1.Low soldering yield for micro inductors?
→ Recommendation: Solderable polyurethane enameled wire
Direct soldering without scraping for 0.05mm ultra-fine wire. Increases yield by 40% and eliminates breakage risk!
2.Motor overload burning the enamel coating?
→ Choose: Non-solderable polyimide enameled wire
220°C heat resistance + double coating. Breakdown voltage >8kV. Eliminates high-temperature failure!
