Free QuoteSolder should instead be applied directly to the tip of the iron and then touched to the solder pad, allowing solder to flow around the lead and into the lead to pad interface. In addition, for “N style”, through-hole, leaded capacitors, solder should be applied to the opposite side of the board from the capacitor.
Capacitors with nickel barrier terminations, which have a solder coat over the nickel, (or solder coated terminations) are restricted to the reflow temperature of the solder. Temperature cycling causes a change in the mean interatomic spacing of the atoms in the crystal lattice, due to variations in thermal energy.
The leaded components should be assembled after the SMD curing step. Leaded film capacitors are not suitable for reflow soldering. In order to ensure proper conditions for manual or selective soldering, the body temperature of the capacitor (Ts) must be ≤120 °C.
When SMD components are used together with leaded ones, the film capacitors should not pass into the SMD adhesive curing oven. The leaded components should be assembled after the SMD curing step. Leaded film capacitors are not suitable for reflow soldering.
Capacitors with such terminations will survive molten solder at 260°C with no discernible leaching effect for several minutes versus less than twenty seconds for the best Pd-Ag alloys (since nickel is relatively insoluble in Sn, Pb or Ag and therefore acts as a barrier to solder leaching).
One recommended condition for manual soldering is that the tip of the soldering iron should be <360 °C and the soldering contact time should be no longer than 3 seconds. Even when suitable solvents are used, a reversible change of the electrical characteristics may occur in uncoated capacitors immediately after they are washed.
