Supply chain

Shenzhen and Dongguan make large numbers of soldering stations and benchtop soldering robots. Direct soldering of enamelled wire needs about 380–420 °C to strip the film — check heating power at that temperature and tip life, and confirm joints by cross-section or pull test.

Buyer FAQ

How do I select a soldering robot for enamelled-wire joints?
Direct soldering through solderable enamel runs at about 380–420 °C, so choose a high-power heater (typically 90–150 W) that recovers temperature quickly between joints. Look for tip temperature stability of about ±5 °C, positioning repeatability of about ±0.02 mm and a solder feeder with adjustable pre- and post-feed. Trial-solder your own coils before ordering.
How do I verify the solder joints?
Inspect wetting visually against IPC-A-610 criteria, then confirm by cross-section that the enamel is fully removed inside the joint and by a pull test on the wire. Watch for copper dissolution on fine wire below about 0.1 mm, which thins the conductor at high temperature; limit dwell time and consider a tin-copper alloy with higher copper content.
What consumables and running costs should I expect?
Tips wear fastest: lead-free solder at 400 °C erodes plating, so tip life is much shorter than at normal electronics temperatures and should be tracked by joint count. Budget for flux-cored solder wire, tip-cleaning materials and fume-extraction filters. Proper extraction is required because enamel and flux fumes at these temperatures are irritating.
