High Performance Cored Solder


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.
