The SFV-CNL04 is a 0.4 x 13.6mm Soldering Tip for heavy-duty applications. FR4/glass fibre substrate material for most standard applications. The SxV tip is for use with the soldering tip handpiece of the PS and MFR platforms. Fixed temperature cartridges and tips offer users a fully safe and thermally effective solution to their lead free soldering needs as well as complete process control. SmartHeat? Technology is unique in that it senses the specific thermal demand directly at the solder pad and delivers the precise quantity and flow of thermal energy during both flux activation and intermetallic bonding phases without any adjustment and calibration.
