In shape BCM/CM, there’s a hollow at the tip end to enable bridging to be corrected and prevent bridging from occurring when drag soldering. Shape BC / C
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.
This shape is All-round type which can be used from any direction and it is available for any works. Therefore it is not only accessible for the soldering beginners but also suitable for the experienced.
This shape is capable of any soldering by placing the tip end in 2 ways: line and face.
Having the very fine tip end, this shape is best for soldering micro components such as 0603, etc and for repairing high-density-mounting P.W.Bs. such as in cellular phones, etc. However, the heat capacity of Shape I is very small and the heat may not be transferred to workpiece sufficiently, which caused the insufficient solder (It’s called Red Eye generally.).
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.
This type has a shape like a knife and is capable of soldering by applying the tip in 3 ways: line, face and point. It is used for soldering at narrow pitches, correction of bridging and drag soldering.
Shape A This shape is like a square pyramid and all-round tip shape such as Shape B. It is possible to solder any surface from small to large.
|Shape A Pyramid-shaped||Shape B Cone-shaped|
Shape H This shape differs from Shape J by cutting the tip end. It is suitable for drag soldering and correction of bridging. * Not available for correcting bridging by standing the tip end like Shape J.
|* Two kinds of Shape H are available.|
