| No-Clean Solder Wire |
| During the processing of our‘No-Clean Solder Wire’, strict quality control management and the advanced drawing process are implemented. Meanwhile, the ratio of both trace metals and impurity substances in the wires are precisely controlled and the welding flux in the wires is distributed uniformly to insure welding continuity. Besides a clean and tidy packing as well as a bright and smooth surface, our wires, in welding process, also provide excellent wettability and weldability, keeping the process in a friendly environment of few smell, few smoke, few flitting, and non-toxic environment. |

Low Melting Point Solder wire |
| The Low-melting solder wire, provided with a lower melting point and easy to operate, is one of the most environment friendly and energy saving solders for welding. It is commonly used in electronic components’ gradient welding as well as the welding of thermolabile parts such as LED, LCD, LNB, radiators, thermosensors, fire alarms, flexible plates, air-condition protectors and the parts for lightningproof and temperature control. In the solder wire, one of Compo’s unique technic known as the Metal Crystal Refinement Technology is adopted to toughen the SnBi58 wire, eliminating its brittleness, thus providing the wire with a fine, clean and bright surface. |
