- Moderate chemical resistance
APPLICATION
- Small power transformer, high-frequency inductors
- Household appliance control board miniature coils
- Micro motor winding, vibration motor coils
- Sensor coils, electromagnetic valve coils
- Consumer electronics coil components adopting low-temperature soldering process
FAQ
Q1: Can this wire be soldered directly without stripping enamel?
A1: Yes. It adopts low-temperature solderable UEW insulation system. Stable soldering can be achieved at 300–320°C. The polyurethane enamel film will fully decompose and volatilize, forming clean solder joints without chemical or laser stripping. Excessively high temperature should be avoided to prevent wire embrittlement.
Q2: Does this wire come with self-bonding coating?
A2: Yes. It is thermoplastic hot-air self-bonding enameled wire. After coil winding, apply hot air heating, the outer bonding layer will melt and bond adjacent wires together. The coil maintains fixed shape after cooling.
Q3: Can I reheat and adjust coil shape after bonding?
A3: Yes. The thermoplastic bonding layer will soften again when heated to bonding temperature. You can reshape and re-fix the coil, bringing greater flexibility for trial production.
Q4: Can this wire be customized?
A4: Yes. We offer customized wire diameters, insulation grades, bonding characteristics, spool sizes, and packaging to meet specific application requirements.
Q5: What information is required for a quotation?
A5:. To provide an accurate quotation, please share the wire dimensions, insulation type, thermal class, required quantity, packaging requirements, and destination country.
