Did you know? 217 °C

SAC305 is 96.5 percent tin, 3 percent silver and 0.5 percent copper. It melts around 217 degrees Celsius, some 34 degrees above the old eutectic tin lead alloy.

Soldering stations

OKI soldering technology

OKI MFR-series soldering and rework stations use RF temperature control based on the Curie effect. Single-channel models (MFR-1110, MFR-1120) accept one handpiece each; 2-channel models (MFR-2210 to MFR-2241) allow simultaneous use of two handpieces, combining a soldering iron with a tweezer or deploying two identical tools. Each station is shipped with a matching handpiece as standard.

Model	Channels	Handpiece(s) included
MFR-1110	1	MFR-H1-SC2 iron
MFR-1120	1	MFR-H2-ST2 iron
MFR-2210	2	MFR-H1-SC2
MFR-2211	2	2x MFR-H1-SC2
MFR-2220	2	MFR-H-ST2
MFR-2222	2	2x MFR-H2-ST2
MFR-2240	2	MFR-H4-TW tweezer
MFR-2241	2	MFR-H4-TW + MFR-H1-SC combination

⚡ RF Curie temperature control - tip maintains set temperature without external feedback loop; fast thermal recovery after each solder contact

⚙ 1 channel vs. 2 channels - MFR-1110/1120 for single-tool workstations; MFR-2240/2241 for parallel soldering and tweezer work

✓ Pre-selected handpiece kits - MFR-2211 (2x SC2) for dual soldering benches; MFR-2222 (2x ST2) for identical two-station configuration

📦 Expandability - 2-channel stations accept a second handpiece later; all MFR upgrade kits (MX-UK1-5) compatible

Typical applications: SMT hand-soldering and rework in electronics manufacturing with high thermal demands, rework on fine-pitch components and in BGA environments, precision soldering in medical and instrumentation applications, and R&D laboratory workstations configured with two handpieces for simultaneous soldering and tweezer work.
