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.
Difference between BC/C type and BCF/CF type Movie helps you to understand it easily.
Shape BC | Shape C | ||
---|---|---|---|
Difference | Shape | This type has a shape like a cone cut at a slant. | This type has a like a column cut at a slant. |
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 ø1, Shape BC has more heat capacity. | ||
Commonality | How to select tip size | Please select the cut surface size depending on the workpiece. | |
Others | In 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. |
Soldering tiny chip parts such as 0603
Put the cut surface to the land. Some IC is specified by manufacturer not to be touched electrode by tip end. The other tip shapes are recommended. |
Soldering chip parts
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.
|
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
Put the cut surface to the lead and drag the tip slowly while feeding solder.
