To confirm Jean-Paul¡¯s post, I also use a Metcal iron with no problems when dealing with these terminal strips. The ability to have the heat source right at the tip with the internal ferromagnetic element eliminates any thermal resistance between the heating element and the tip. This provides continuously regulated heat at the tip to quickly flow the solder and reduce contact time with the part.
It¡¯s also nice to be able to select the right tip size for the job.
