The lead-free solder SN100C is an alloy of tin, copper, nickel and germanium. Its unique properties make it possible to achieve high productivity in soldering processes to produce cost effectively reliable joints. Special features include high fluidity, low copper erosion, low drossing, superior wetting and freedom from shrinkage defects. The number of companies using SN100C has grown dramatically since its first application in 1999 in the soldering of VCR boards.

Customer Feedback

Since it was first used in commercial mass production in March 1999 the number of soldering lines using Nihon Superior's SN100C stabilized tin-copper eutectic alloy has continued to grow rapidly. An opportunity for the voice of SN100C users, including some non-Japanese, to be heard in the market has been provided by a series of nine “Visit the SN100C User” articles in the leading Japanese industrial newspaper. All of these users set a high value on SN100C, because it provides good solderability and smooth, bright, well-formed fillets while providing joint reliability at least equal to that of Sn63/Pb37.
Users also point out how easy it is to recycle and the cost advantage of not containing silver contents.
These reports provide an explanation of why the use of SN100C is spreading so rapidly.

Adoption of SN100C

SN100C was used for VCR in 1999. Since then, it has been used for many product in electronics and the business is expanding rapidly.
