MaterionEnvironmentally sealed connectors from Materion’s new gold-based solder for RoHS-compliant electronics, AuSn Plus, is especially designed to attach die and seal lids in packages that will subsequently be soldered with SAC (tin-silver-copper) alloys in lead-free circuit assembly processes. The addition of indium to traditional AuSn 80/20 raises its melting point from 278°C to 306°C, providing protection against secondary reflow, loss of hermeticity, and critical component shift during the SMT soldering process. AuSn Plus has comparable physical properties to AuSN, but with slightly higher processing temperatures (near 350°C, similar to high-lead solders) and, due to the inclusion of indium, which is substituted for some of the tin in the Au4Sn intermetallic compound, is slightly harder and less ductile than the original AuSn alloy. AuSn Plus is also a eutectic alloy, meaning that it has a single melting point or the narrowest pasty range possible — in this case, a melting point between 300°C and 309°C. The AuSn solder that is traditionally used to seal hermetic packages and attach die melts at 278°C. If it is used in packages that experience SnPb reflow temperatures, a 48°C thermal safety margin ensures that it will not inadvertently melt during the circuit assembly’s soldering cycle; however, if used in packages that experience Pb-free reflow cycles, the safety margin for standard AuSn solder shrinks to only 18°C. This significantly smaller margin increases the risk of secondary reflow due to conditions that can drive up peak temperatures — including improperly profiled PCBs, uncalibrated ovens, and varying thermal densities in PCB layouts — and can cause a loss of hermeticity or shift of critical component and impair the functionality and/or reliability of the device. The new process-proven, patent-pending AuSn Plus solder alloy expands the safety margin between melting points in Pb-free reflow cycles to a robust 46°C and is now commercially available for testing and qualification.

Newark, An Avnet CompanyEnvironmentally sealed connectors from Newark and Souriau, stocks SOURIAU’s 8D Series MIL-DTL-38999 Series III / EN3645 glass-sealed hermetic connectors, which deliver high-hermeticity performance in a wide range of military and aerospace applications. The series is available with robust passivated or nickel-plated stainless steel shells in nine sizes spanning #9–25; easy-to-install square flange, easy-to-replace jam nut, compact solder-mount, and weld-mount quick receptacle styles; screw coupling according to EN3645 and MIL-DTL-38999 standards; numerous orientation/polarization options; silicone elastomer seals; 3–66 gold-plated ferrous alloy signal and power contacts in six sizes spanning # 4–22D; and solder cup or PCB terminations. It is rated for 3–60A per contact, a minimum of 45dB (Class Y) or 65dB (Class N) shielding at 10GHz, 5,000MΩ insulation resistance under 500VDC, operating temperatures extending from -65°C to 200°C, and 500 mating cycles. It is also resistant to 48 (Class N) or 500 (Class Y) hours of salt spray, fluids per MIL-DTL-38999, and short immersion in gasoline, mineral hydraulic fluid, and synthetic hydraulic fluid. Other options include special fuel tank versions designed for long-term fuel immersion and maximum operating temperatures of 105°C and 230V-qualified versions designed to help reduce overall cable weight. environmentally sealed connector products
