Recommended reflow profile.

 

Reflow soldering, vapour-phase soldering. A maximum soldering temperature of 260ºC during 10 s should not be exceed for (see recommended soldering profile with maximum and minimum temperature-time).

 

 

The reflow condition recommended is according to the machine used by our company. Big differences will arise as a result of the type of machine, reflow conditions, method, etc used.

  1. Rated Inductance LR: Measured at frequency fL, with impedance analyser WK3260 with 3MHz installed.
  2. Q Factor Qmin: Measured at frequency fL, with impedance analyser WK3260 with 3MHz installed.
  3. Self-resonance frequency fmin Measured at frequency fL, with impedance analyser WK3260 with 3MHz installed.
  4. DC resistance RmaxMeasured at 20ºC ambient temperature, measuring current <IR.
  5. Sensitivity: Measured with Helmholtz coils 5 turns, 160mm ∅, + waveform generator Agilent 33120A + oscilloscope Agilent 54622A. Contact PREMO RFID for complete measurement specification.
