How to use Shape D and examples
This shape is capable of any soldering by placing the tip end in 2 ways: line and face. Therefore it requires soldering skill such as Shape B.
 |
Line example
Shape D is also available for soldering at narrow pitches by placing the tip end in Line. |
The followings introduce four works by placing the tip end in Face.
Please try the tip shape showed bellow if in trouble such as bridging, faulty fillet formation, insufficient wetting, etc.
Shape D has the special application of Heavy Duty Type.
Shape D has the special application of Long Life Type.
Soldering chip parts
 |
Put the tip end 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, The other tip shapes are recommended. |
Drag soldering
 |
Put the tip end to the leads and drag it slowly. Apply flux to leads and land pads before soldering. It prevents the troubles such as solder bridge. See the movie for further details, The other tip shapes are recommended. |
Pre-tinning lead wire
 |
Put the cut surface to the lead and drag the tip slowly while feeding solder. |
Point soldering

QFP Put the tip end to the leads and drag it slowly. See the movie for further details, The other tip shapes are recommended. |
Soldering cup terminals
 |
Get rid of gold plating of terminal and pre-tin lead wire. It makes solder spread over the terminal easily and prevents soldering defect. For further information, see “Soldering cup terminals”. |
Melting and removing coil coatings
