They are widely used for temperature compensation but can also (typically 260°C / 30 s). achieve temperature control of printed circuits. Its silver - palladium - platinum metallization provides a high degree of resistance to dewetting of the terminations during soldering |**Types**

NB products are compatible with a wide range of soldering conditions consistent with good manufacturing practice for surface mount components. This includes Pb free reflow processes with peak temperatures up to 270ºC. Recommended profiles for reflow and wave soldering are shown below for reference.

- a) The visual standards used for evaluation of solder joints will need to be modified as lead free joints are not as bright as with tin-lead pastes and the fillet may not be as large. - b) Resin color may darken slightly due to the increase in temperature required for the new pastes. - c) Lead-free solder pastes do not allow the same self alignment as lead containing systems. Standard mounting pads are acceptable, but machine set up may need to be modified. **==> picture [167 x 98] intentionally omitted <==** **----- Start of picture text -----**
