Nathan Trotter Announces Solder Alloy Patent Expiration


Reading time ( words)

Leading tin and solder alloy manufacturer, Nathan Trotter, in cooperation with North American master representative e-tronix, Inc., announced the availability of NT100Ge lead-free solder bar and wire products with an alloy composition equivalent to that of the well-known SN100C solder. Effective March 15, 2019, the patent US618055/EU985486/JP3152945 held by Nihon Superior Sha Co., Ltd. has expired, allowing the alloy composition of SN100C to be produced in bar and wire form without restriction. Nathan Trotter has formulated NT100Ge as a drop-in replacement for existing SN100C applications, providing expanded access to cost-effective wave solder products.

“Electronics assemblers have appreciated the performance capabilities of the SN100C alloy for some time,” says Luke Etherington, vice president of Business Development at Nathan Trotter. “Our new NT100Ge solder bar and wire will deliver an identical alloy composition and excellent wave soldering performance consistent with that of SN100C, but without the price premiums. This, combined with Nathan Trotter’s more than two centuries of metals manufacturing expertise, our broad global importing resources and high-volume production capacity, offers electronics manufacturers a robust and cost-competitive supply chain that is unmatched.”

Nathan Trotter’s NT100Ge is a lead-free alloy comprised primarily of tin, with additions of nickel, copper and germanium. Benefits of the alloy include formation of an aesthetically appealing solder joint with a bright, smooth appearance, compatibility with wave and selective soldering machine metals, and reduced copper dissolution within the soldering process. In addition to the NT100Ge performance advantages, Nathan Trotter’s ongoing investment in its bar and wire manufacturing competency and resource underscores the company’s commitment to ensuring next-generation production systems to satisfy product purity and supply requirements. The company is the largest bar and wire solder supplier in North America, providing its customers with the highest quality metals. With a production volume of approximately two million pounds per month, industrial and electronics manufacturers are assured of risk-free supply to meet production demands.

Partnering with multi-award-winning master representative, e-tronix, Nathan Trotter customers are supported by an extensive and knowledgeable North American sales and technical consulting network. The e-tronix team has a combined 60 years of electronics industry experience and in-depth process know-how to help customers select products that will maximize performance and minimize cost.

“The addition of NT100Ge to the Nathan Trotter solder bar portfolio allows electronics specialists to enjoy superior wave solder process performance at an industry-best cost,” explains Erik Stromberg, President of e-tronix. “Nathan Trotter’s metals manufacturing expertise and economies of scale along with the service and technical support of our team ensure customers can meet their demanding reliability, high-yield, low-cost objectives.”

Practical Implementation of Assembly Processes for Low Melting Point Solder Pastes (Part 1)

07/16/2019 | Adam Murling, Miloš Lazić, and Don Wood, Indium Corporation; and Martin Anselm, Rochester Institute of Technology
Since 2006 and the implementation of the RoHS directive, the interest in bismuth-tin solder alloys—whose melting point around 140°C is very desirable because it allows for the use of lower temperature laminate materials and reduces thermal stress on sensitive components—has only increased as the industry has searched for Pb-free alternatives to the chosen standard, SAC305, which melts at considerably higher temperatures than the incumbent tin-lead alloys.

Surface Treatment Enabling Low-Temperature Soldering to Aluminum

07/15/2019 | Divyakant Kadiwala, Averatek Corporation
An increasingly popular method to meet the need for lower cost circuitry is the use of aluminum on polyester (Al-PET) substrates. This material is gaining popularity and has found wide use in RFID tags, low-cost LED lighting, and other single-layer circuits. However, both aluminum and PET have their own constraints and require special processing to make finished circuits.

Failures and Reliability in Soldering

07/09/2019 | Michael Gouldsmith and Zen Lee, Thermaltronics
The definition of failure is "the lack of success in doing or achieving something, especially in relation to a particular activity." If the activity is concerning a soldering process, such a failure can have a downstream impact far beyond the actual solder joint. In this regard, it is first necessary to understand what constitutes a good solder joint because appearance is too often deemed a success.
