Select a tip with an inside diameter larger than the lead diameter and an outside diameter aqpproximqately the same size as the pad.
Choosing the correct Series
The SP440 features high durability SDC desolder cartridges, designed
for high heat transfer, making desoldering on multi-layer boards
much easier. Desolder cartridges are available in two temperature
ranges (600 and 700 series). A typical board usually requires a
700 series tip. Try a 600 series tip first for thermally sensitive
components or small, single-sided boards.
