How to use Shape D and examples

This shape is capable of any soldering by placing the tip end in 2 ways: line and face. Therefore it requires soldering skill such as Shape B.

Tip Shape D Line example
Line example

Shape D is also available for soldering at narrow pitches by placing the tip end in Line.
T12 series has ten kinds of Shape D which has the variation of Line width from 0.5mm to 1.2mm.


Soldering tiny chip parts such as 0603

Soldering tiny chip parts such as 0603

Put the tip end to the land.
* Soldering tip in the picture is T30-D06 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.

Soldering chip parts

Use it for soldering chip part.

Put the tip end to the land and drag the tip slowly while feeding solder.

Drag soldering

Use it for drag soldering.

Put the tip end to the leads and drag it 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.

Drag soldering


Pre-tinning lead wire

Use it for pre-tinning lead wire.

Put the cut surface to the lead and drag the tip slowly while feeding solder.


Point soldering

Use it for point soldering.

PTH

1. Put the tip end to the land pad and PTH at one time to heat them.
2. Feed solder to form smooth fillet on the land pad.
Use it for point soldering.

QFP

Put the tip end to the leads and drag it slowly.

The other tip shapes are recommended.

Soldering cup terminals

Use it for soldering cup terminals.
1. Put the cut surface to the lead and terminal at one time to heat them.
2. Feed solder to form smooth fillets.

Get rid of gold plating of terminal and pre-tin lead wire. It makes solder spread over the terminal
easily and prevents soldering defect. For further information, see “Soldering cup terminals”.


Melting and removing coil coatings

Use it for melting and removing coil coatings.
1. Put the cut surface to the coil and terminal at one time to heat them.
2. Feed solder.

The other tip shapes are recommended.
