How to use Shape J and examples
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
Soldering tiny chip parts such as 0603
![]() | Lay down the end pad section and put the tip to the land. * Soldering tip in the picture is T30-J with an N2 system iron for pre-heating effect. Some IC is specified by manufacturer not to be touched electrode by tip end. |
Drag soldering
![]() | Lay down the end pad section and drag the tip slowly. Apply flux to leads and land pads before soldering. It prevents the troubles such as solder bridge. |
Correcting Bridging
![]() | If the bridge amount is small Stand the tip on end and drag the tip slowly. Please operate with clean tip. |
![]() | If the bridge amount is large
|
Soldering at the narrow pitches
![]() | You can hold the grip with the natural angle (Refer to A) while soldering with Shape J, which has the same high-angle of tip end (Refer to B) as Shape I.
