How to use Shape BC/C and examples

This type has a shape like a cone or column cut at a slant, which allows users to select the cut surface size depending on the workpiece.
It is used for drag soldering and pre-tinning of lead wires.

Type F, tinned surface only, is available for Shape BC/C. Try Type F when troubling with excessive solder amount or bridge to neighboring parts.
* Not suitable when heavy heat capacity is required.

Heat capacity
of tip
In Shape BC with its conical shape, the nearer to the base, the thicker the diameter. Therefore, although these types have the same diameter Φ1, Shape BC has more heat capacity.

HAKKO Recommendations for Selection of Tip Size (Diameter)

OthersIn case of a chip condenser, we recommend soldering it with Shape BC or C to form ideal solder fillet, which can be hardly formed with Shape B or D.

Shape BC/C has the special application of Long Life Type.

Soldering chip parts

Use it for soldering chip part.

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

Some IC is specified by manufacturer not to be touched electrode by tip end.


See the movie for further details,


Drag soldering

Use it for drag soldering.

Put the cut surface to the leads and drag it slowly.

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

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.

See the movie for further details,


Point soldering

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

See the movie for further details,


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.
