Soldering Tip: Shape BC/C


How to use Shape BC/C + Examples

Shape BC and C

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.

A variation of Shape BC/C (Type F) with tinned surface only is available. Try BCF/CF when facing issues with excessive solder amount or solder bridges. Read more on the difference between BC/C and BCF/CF here.

Shape BC vs C

Differences Shape BC Shape C
Shape The tip tapers off towards the end (like a cone) The tip radius is constant (like a column)
Heat Capacity Higher Lower

NOTE: Some IC are specified by the manufacturer not to be touched on the electrode by tip end.

Soldering Chip Parts

BC Chip Soldering

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

NOTE: Some IC are specified by the manufacturer not to be touched on the electrode by tip end.

Drag Soldering

BC Drag Soldering

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

NOTE: Apply flux to the leads and land pads before soldering. It helps to prevent problems such as solder bridges. 

Pre-tinning Lead Wire

BC C Pre Tinning Wire

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

Point Soldering

BC/C Point Soldering

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

Melting and Removing Coil Coatings

BC/C Removing Melting Coil Coating

1. Put the cut surface to the coil and terminal at one time to heat them.
2. Feed solder.
