If you enjoy soldering SMD components such as 0805 and 0603 size diodes and transistors alongside other components, as well as some surface mount items such as USB connectors and capacitors, DL12 is well suited to normal SMD operation . Not too big like Hakko Hoof Tips and not too small or chunky (tapered tips) to solder into. For even higher density circuit boards, such as those used in cellular phones and compact communications devices, purchase Hakko's curved tips. They work wonders on their dense boards.
