Drag soldering
The following shapes are recommended. Apply flux to leads and land pads before soldering. It prevents the troubles such as solder bridge and insufficient solder.
* Click icon and jump to each tip shape details.
Shape BCM/CM having the hollow with its surface is recommended. It is also suitable for correcting bridging. | |
The various shapes are available for correcting bridging. For further details, see the following page which also introduces the causes of bridging. |
Use Shape BCM/CM
This shape has the hollow section to its cut face, providing high solder retention capability. It offers other recommended usages.
Feed solder on a hollow section and drag the tip along slowly. |
Use Shape BC/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.
Put the cut surface to the leads and drag it slowly. | |
Use Shape B
This shape is all-round type which can be used from any direction and is easy to hold at any position. It offers other recommended usages.
Put the tip end to the leads and drag it slowly. Check the right timing to feed solder. |
Use Shape D
This type has a shape like a flat-blade screwdriver and is capable of soldering by applying the tip in 2 ways: line and face. It is available for any works.
Put the tip end to the leads and drag it slowly.
|
Use Shape J
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 offers other recommended usages.
Lay down the end pad section and drag the tip slowly. Check the right timing to feed solder. |
Use Shape K
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.
PTH Put the tip to the leads while laying down the entire blade and drag it slowly. * Lay the blade down to thoroughly transfer sufficient heat to the pattern. | |
QFP Put the tip to the leads while laying down the entire blade and drag it slowly. * Lay the blade down to thoroughly transfer sufficient heat to the pattern. |
Use Shape H
This shape differs from Shape J by cutting the tip end. It offers other recommended usages.
Put the pad section to the leads and drag the tip along slowly. |
