Soldering at Narrow Pitches


When dealing with micro-soldering, it is common to come across workpieces with tight or narrow spacing. Check out the following for Hakko's recommended soldering tips for soldering at narrow pitches!

Tip Shape 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. Recommended when Shape I has insufficient heat capacity
Shape S This shape is different from Shape B, C, D and I by the special shape (thinner tip) which prevents tip end from touching nearby components. Recommended when Shape I has insufficient heat capacity

Shape I

Shape I Narrow Soldering

For workpieces with narrow pitches, the Shape I is the best tip to prevent touching nearby ICs.

Shape K

Shape K Narrow Soldering

Stand the blade on the pointed end on the leads of the IC chip. Ensure that the tip does not come into contact with the IC. 

Shape S

Shape SB

The special shape of the Shape SB fine tip end prevents it from touching nearby chips.

Shape B VS Shape SB

Shape J

Shape J vs Shape I

The fine pointed end of shape J enables easier soldering on narrow workpieces.

In addition, the bent tip allows you to solder at the same angle as shape I (angle B) while maintaining a more natural grip angle (angle A), reducing hand fatigue.
