How to use Shape J and examples

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 is used for drag soldering and correction of bridging.

Lay down the end pad section and put the tip to the land.
* Soldering tip in the picture is T30-J 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

Use it for drag soldering.

Lay down the end pad section and drag the tip slowly.

Apply flux to leads and land pads before soldering. It prevents the troubles such as solder bridge.



    Check the right timing to feed solder.


Correcting Bridging

Use it for correcting Bridging.

If the bridge amount is small

Stand the tip on end and drag the tip slowly.

Please operate with clean tip.


Use it for correcting Bridging.

If the bridge amount is large

Lay down the end pad section and drag the tip slowly while putting the tip on the solder in the bridged section.

Please operate with clean tip.

Soldering at the narrow pitches

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.
