The long-awaited acoustic solder has finally arrived!

The concept of SS-47 is the elimination of individuality. Creating items that maximize the characteristics of cables and connectors. The dedicated solder SS-47 for the sound uses tin with a high purity of 4N (99.993% or more) which is the base of the tin with the maximum elimination of impurities. Introducing pure silver generously to improve conductivity. The amount is 4.7% which is unprecedented. Furthermore in order to make eutectic solder 1.7% of copper which has the highest conductivity after silver is mixed.

Of course thoroughly study the flux. Based on the control of surface corrosion the residual chlorine is kept to 0.12% or less and the flux used for SS-47 is made of a special compound which shows a marvelous workability with a spreading rate of 83%.

These compounding ratios were not judged only by numerical data and workability but sound quality was given top priority as an audio solder. SS-47 is an acoustic solder that was finally completed by carrying out hearing tests on proto models with various mixing ratios many times to realize elimination of individuality. SS-47 is the strongest tool to maximize the performance of the materials used and to realize stress-free craft work.

Material / mixing ratio

Normal solder has a tin purity of about 99.9% (3N) in terms of cost. SS-47 has been further refined to eliminate impurities to the limit and it uses high-purity tin of 99.993% (4N) or more. It also contains silver and copper for the purpose of improving conductivity and preventing solder erosion.

Moreover in the case of normal alloy solder the silver compounding ratio is 3 to 3.5% but the amount of SS-47 4.7% was generously added. In addition 1.7% of copper which has the highest conductivity next to silver among metals is mixed. This compounding ratio dramatically improved the conductivity and succeeded in setting the eutectic point to 217 degrees.

Pursuit of ease of use

Spread rate 83%. With a 40W soldering iron the solder will penetrate in a few seconds. In addition it cools quickly at the eutectic point of 217 degrees and the work is completed without damaging the surrounding materials with heat. Whatever your skill youll be amazed at the overwhelming workability and beautiful finish.

Electrical signals flow on the surface of matter. This is called the skin effect and especially in the high frequency band. SS-47 has the greatest advantage of eutectic solder the surface is smooth and does not interfere with the signal characteristics. Smooth surface. This means that there is no signal distortion and distortion is minimized.
