Power through ground-plane joints without losing your set temperature.
The YIHUA 939D+ IV Soldering Station pairs a 90W heating core with digital control, so temperature recovers in under 3 seconds under heavy load instead of drifting mid-joint. Built for SOP, DIP, and SOIC soldering and desoldering, where a standard 40-60W iron struggles.
Top Features
- 90W High-Power Core: Fast recovery and even heat penetration cut down on cold joints.
- Dual-Readout LCD: Set and actual temperature shown side by side, with °C/°F conversion.
- 3-Stage Memory: Store your go-to temperatures and switch between them instantly.
- Smart Sleep with Shake-to-Wake: Sleeps after 0/5/10/30 minutes idle, wakes with a gentle shake of the handle.
- Password-Locked Settings: Stop temperature settings getting knocked out of place on a shared bench.
