| INTRODUCTION OF PRODUCTS |
| This product is a material for electric contacts. One to five thin layers of precious metal, such as glod, silver and paladium, are clad on the edge of the long tape of conductive metals.Wide selection for the size of cross-section is varied from 0.2mm to 2.0mm in thickness and from 5.0mm to 40.0mm in width and remarkable long rolls is avalable. Formerly contacts are manufactured by assembling precious metals with conductive metals by way of spot welding and brazing. Howerver, adopting this material, the manufacturing process of contacts will be simplified only to require press processing..Thus, the material can make the contacts small sized and lightweight and can simplify the assembling process. Moreover it can achieve big reduction of the manufacturing cost. |

| INTRODUCTION OF TECHNOLOGY |
| In the past days, they say it is inpossible to in bed thin precious
metal layer on the edge of conductive metal tapes because of incidental
void and limitation in thickness of precious materials layer due to the
jointing method such as welding and/or brazing. This product employs a cladding technique which does not melt any base metal and it makes this product can achieve excellent reliability and joint of customer's optional layer without any void at jointing surface with reduced cost. |
| TYPICAL APPLICATIONS |
| Hook switch, used for the multi-functioned telephone equipment, is
a part of noteworthy application of this material. According to the increase of number of functions of such equipment, more and more devices are needed for the circuits which functioned by hanging on and up the telephone equipment. This material have made manufacturers to accomplish the production of smallest and lightest hook switches at lowest cost which were achieved by former technologies. |
