The SS-47 concept eliminates individuality. To create an item for maximizing the characteristics of a cable or connector. The acoustic soldering \"SS -47\" uses tin with a high purity of 4 N (99.993% or more), which eliminates impurities to the limit. In order to improve the conductivity, pure silver was generously introduced. That amount is 4.7%, which is more than ever. In addition, 1.7% of copper, which is the second most conductive metal after silver, is blended to make a eutectic solder.
Of course, flux (yani) was also fully investigated. Based on the suppression of surface corrosion, residual chlorine is kept below 0.12%. Moreover, the flux used in SS-47 is specially formulated with substances, and the spread rate is 83%, which shows excellent workability.
These ratios are not based solely on numerical data and workability, and sound quality is the highest priority for audio solders. The prototype model with various blending ratios has been subjected to hearing tests many times to realize the "elimination of individuality," and the final sound solder is the SS-47. The SS-47 is the most powerful tool for maximizing the performance of the components used and for creating stress-free craftwork.
Material/blend ratio
Normal solder has a tin purity of about 99.9% (3N) from a cost perspective. The purity of \"SS -47\" is further improved and impurities are eliminated to the limit, and high purity tin of more than 99.993% (4 N) is adopted.
It also contains silver and copper to improve electrical conductivity and prevent solder from being eaten. In addition, in the case of ordinary alloy solder, the ratio of silver is 3 ~ 3.5%, but \"SS -47\" uses a generous amount of 4.7%.
It also contains 1.7% copper, which is the second most conductive metal after silver. This blending ratio dramatically improved the conductivity, and we succeeded in setting the eutectic point to 217 degrees.
pursuit of ease of use
Spread rate 83%. If you have a 40 W soldering iron, the solder will penetrate in a few seconds.
It also cools quickly at a eutectic point of 217 degrees, and finishes the work without causing the surrounding material to suffer from heat. And no matter your skill, you'll be amazed at the sheer workability and beauty of the finish. Electrical signals flow on the surface of a substance. This is called the skin effect, especially in the high frequency band. SS-47 has the greatest advantage of eutectic solder: the surface does not interfere with smooth finish signal characteristics.
Surface smoothing. This means that the signal is not disturbed and the distortion is minimized.
