T12-KR Knife Soldering Tip (T15-KR) 4.7mm 1.5mm/45° x 11mm

How to use Shape K and examples

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.

Shape K has the special application of Long Life Type.

Soldering tiny chip parts such as 0603

Put the tip to the leads while laying down the entire blade.
* Soldering tip in the picture is T30-KU with an N2 system iron for pre-heating effect.
Some IC is specified by manufacturer not to be touched electrode by tip end.

The other tip shapes are recommended.

Drag soldering

PTH

Put the tip to the leads while laying down the entire blade and drag it slowly.
Apply flux to leads and land pads before soldering. It prevents the troubles such as solder bridge.

* Lay the blade down to thoroughly transfer sufficient heat to the pattern.

QFP

Put the tip to the leads while laying down the entire blade and drag it slowly.
Apply flux to leads and land pads before soldering. It prevents the troubles such as solder bridge.

* Lay the blade down to thoroughly transfer sufficient heat to the pattern.

Correcting Bridging

If the bridge amount is small

Stand the blade on edge and drag the tip slowly.
Please operate with clean tip.

* Do not stand the blade up at too steep angle. Doing so will damage the P.W.B.

If the bridge amount is large

Lay the blade down and drag the tip slowly.
Please operate with clean tip.

Soldering at the narrow pitches

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

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