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.).
Shape I has the special application of Heavy Duty Type.
|Very fine tip end makes it easy to solder a tiny chip.|
|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.
