Soldering Tip: Shape D


How to use Shape D + Examples

Shape D Line and Face

This type has a shape like a flat-blade screwdriver and can be soldered by applying the tip in 2 ways: line and face. The width (size of tip) suitable for the workpiece can be selected, and it can be used for any soldering work.

It is suitable for soldering at narrow pitches by using the line portion of the soldering tip. The T12 Series has 10 variations of shape D with line width from 0.5mm to 1.2mm

Soldering Tiny Chip Parts (0603)

Soldering Tip shape D Put the tip end to the board.
*Soldering tip in the picture is T30-D06 with an N2 system iron for pre-heating effect.

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

Soldering Chip Parts

Shape D Chip Soldering

Put the tip end 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

Shape D Drag Soldering

Put the tip end to the leads and drag the tip slowly downwards while feeding solder. Take note of when to feed solder to prevent excess 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

Shape D Pre Tinning of Wires

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

Point Soldering

Shape D Point Soldering

Pin Through Hole (PTH)

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.

Shape D QFP Soldering

Quad Flat Pack (QFP)

1. Put the tip end to the leads
2. Feed solder and drag the tip slowly outwards

Soldering Cup Terminals

Shape D Soldering cup terminals

1. Place the lead wire into the cup terminal.
2. Put the cut surface of the soldering tip to the lead and terminal together to heat them.
3. Feed solder, allow it to melt and quickly remove the soldering iron. 

NOTE: Removing gold plating of terminal and pre-tinning lead wire will make solder spread over the terminal easily and prevents soldering defect.

Melting and Removing Coil Coatings

Shape D Removing Coil Coating

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