How the S-205 Fits into PCB Assembly
- High-frequency heating provides fast heat-up and rapid recovery for lead-free solder.
- Digital calibration, password-protected temperature lock, and auto-sleep help maintain process quality.
Key Selection Parameters for Buyers
- Confirm local voltage (standard: AC220V/50Hz).
- Choose tip geometry to match your component mix (an 8 mm tip is the usual working size).
- Define ESD, tip-to-ground, and temperature-lock requirements for process control.
ROI Perspective
Stable tip temperature reduces cold joints and rework at hand-soldering stations. Southern Machinery offers application support and spare parts for a long service life.

FAQ
What temperature range does the S-205 support?
50–600 °C with ±2 °C stability, covering lead-free alloys.
What is the max power of the S-205?
150 W high-frequency heating, normally used with an 8 mm tip.
Does the S-205 have temperature calibration?
Yes, digital calibration is built in.
Can the S-205 protect process settings?
Yes, password-protected temperature-lock mode prevents unauthorized changes.
Is the S-205 for BGA rework?
No. BGA rework stations (SR-430A, T-870A) cover BGA rework; the S-205 is a hand soldering station.
