Soldering at the narrow pitches

The following tip shapes are recommended. Please select the best shape by following each feature.

* Click icon and jump to each tip shape details.

Shape BCM/CM Shape BC/C Shape B Shape D Shape I Shape J Shape K SMD Type : Shape Quad SMD Type : Shape Tunnel SMD Type : Shape Spatula Shape A Shape H Shape R Narrow-pitch Soldering Type : Shape S Shape SB Special Applications Type Shape Concave

Feature Remarks
Shape I This shape has a thin conical end and is an ultrafine tip. It is best suited for soldering at narrow pitches. -
Shape K This shape has a shape like a knife. It is also available for correcting bridging and drag soldering. These shapes are recommended when unmolded solder caused by insufficient heat capacity with Shape I
Shape S This shape is changed from Shape B, C, D and I by the special shape which prevents tip end to touch the nearby ICs.


Use Shape I

This shape has a thin conical end and is an ultrafine tip. It is used for soldering a tiny chip at narrow pitches.

Use it for 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.


Use Shape J

This shape differs from Shape B and I by bending the tip end and is capable of soldering by applying the tip in 2 ways: face and point. It offers other recommended usages.

Use it for soldering tiny chip parts such as 0603.
Enlarge the tip end,

You can hold the grip with the natural angle (Refer to A) while soldering with Shape J, which has the same high-angle of tip end (Refer to B) as Shape I.

Use it for soldering tiny chip parts such as 0603. Use it for soldering tiny chip parts such as 0603.
Shape J Shape I


Use Shape K

This type has a shape like a knife and is capable of soldering by applying the tip in 3 ways: line, face and point. It is used for soldering at narrow pitches, correction of bridging and drag soldering.

Use it for soldering at the narrow pitches.

Stand the blade on edge and put the tip end on the leads of the IC chip.

Zoom Viewing from the front also shows that the tip end does not come in contact with the IC.


Use Narrow-pitch Soldering Type : Shape S

This shape is derived from Shape B, C, D and I. It is used for soldering tiny chips at the narrow pitches.

Use it for soldering at the narrow pitches.

The special shape of fine tip end prevents its tip end from touching nearby chips.

When soldering with “900M-T-B”, tip end can touch the chip on the left side even if your hand shakes a little.
