How to use Shape I and examples
Having the very fine tip end, this shape is best for soldering micro components such as 0603, etc and for repairing high-density-mounting P.W.Bs. such as in cellular phones, etc. However, the heat capacity of Shape I is very small and the heat may not be transferred to workpiece sufficiently, which caused the insufficient solder (It’s called Red Eye generally.).

Soldering at the narrow pitches
|It is easy to work with Shape I at the narrow pitches in which the tip end of Shape B touches the nearby ICs.
* The tip in the photo is T12-ILS.
T12 series has the most variation of Shape I in HAKKO products:
T12-I, T12-IL and T12-ILS.
