Joining Dissimilar Materials

The Issue of Coefficient of Thermal Expansion (CTE) Mismatch

Yes, S-Bond can join a wide variety of materials, including aluminum, copper, stainless steel, refractory metals and ceramic to metal brazing with aluminum oxide, aluminum nitride, silicon carbide and other oxide, nitrides and carbides… however, with this wide variety of materials joining capability, we have a lot of inquiries about aluminum soldering to stainless steel or aluminum oxide, graphite bonding to aluminum, titanium to silicon carbide, etc. (more…)

Ceramic to Metal Bonding

S-Bond® active solders enable ceramic to metal bonding and sapphire to metal bonding as well as to each other. S-Bond alloys have active elements such as titanium and cerium added to Sn-Ag, Sn-In-Ag, and Sn-Bi alloys to create a solder that can be reacted directly with the ceramic and sapphire surfaces prior to bonding. S-Bond alloys produce reliable, hermetic joints with all metals…including steel, stainless steels, titanium, nickel alloys, copper and aluminum alloys. (more…)

What is S-Bond® 220?

S-Bond 220 is a solder material (Sn-Ti-Ag) and a process by which most materials, including dissimilar metallic and ceramic materials can be joined. It is a new family of solders, developed and patented by S-Bond Technologies. The material is an activated solder with elements added to the alloy that react with surfaces during joining and adhere to any surface films that normally disrupt wetting and bonding. The characteristics of S-Bond 220 include: (more…)

S-Bond to Sell EWI’s Lead-free, Fluxless Solder

S-Bond Technologies and EWI have signed an agreement granting S-Bond Technologies the ability to distribute EWI’s patented lead-free, fluxless solder marketed by EWI as EWI SonicSolder®. The agreement is effective immediately. SonicSolder® is an active solder that permits the cost effective fluxless joining of aluminum, copper, other metals, glass, and ceramics without the need for plating. (more…)

Welcome to the new S-Bond blog!

We are pleased to introduce our Blog as part of our commitment to communicate effectively with our customers, our prospective customers and anyone interested in our S-Bond, active solder bonding technology. This blog will feature news, technical updates, application updates, and general discussions about bonding and assembly of components.

We look forward to you visting our website and participating in the blog. As the blog develops interest, we hope to have good discussions about the active solder joining and related bonding technology and applications. Feel free to comment in our blog space.

S-Bond Active Solder Bonding

S-Bond was developed between 1995 – 2005 during which the materials and process technology has progressed to encompass the joining of most metals, semiconductors, ceramics and many composites of metals/ceramics. Key to the success of S-Bond active solders are they contain combinations of active metals such as titanium with rare earths such as cerium. These very active solders permit fluxless joining and eliminates the need for Ni or Cu plating before solder joining. SBT has also developed methods to actively solder bond and hermetically seal ceramics such as Al2O3, sapphire, quartz and zirconia. Please review our website, www.s-bond.com and take a look at our brochure and technical literature on the site. We would appreciate if you would share this blog and our website with your colleagues and customers, as S-Bond is an excellent solution for many dissimilar materials bonding applications. (more…)
