GTH-RMA

High Performance Cored Solder

Cored solder designed for robot soldering offering high wetting with
performance for through hole PCB soldering.
Type RMA.

Feature① Possible to stable dragging soldering.

Evaluation Dragging solder test

■ Test Method： Solder by Automatic machine onto PW Board with Insert parts.
Solder Iron Tip Temp ： 350℃ Dragging Speed ： 4.5mm/s
Feeding volume ： 220mm Feeding speed ： 25mm/s
Device pin distance ： 2.54mm pitch
Board with oxidation treatment used, Test implemented after oxidation treatment （250℃、60sec.）

Feature② Better stability of wetting for point soldering.

Evaluation Point soldering test

■ Test Method： Solder by automatic machine onto PW Board with Insert parts （Point soldering）
Solder Iron Tip Temp ： 340℃
Feeding Volume ： 25mm
Feeding Speed ： 20mm/s
Cu pad size ： 5×3mm
Board with oxidation treatment used, Test implemented after oxidation treatment （250℃、60sec.）

Feature③ Reduce flux splattering in the soldering process.

Evaluation Splattering test

■ Test Method： Solder Cu plate by point soldering automatically.Cu plate is placed onto thermal paper, then number of flux splattering is counted.
Solder Iron tip temp ： 320℃、350℃、380℃
Feeding volume ： 5mm Feeding speed ： 10mm/s
Soldering points ： 20points Cu Pad size ： 90×15mm
