I would try a PTFE (Teflon) wire or Teflon protected wire or you could try anodized aluminum. Its getting more and more interesting how the lead free era develops. Just a thought I wander how long its going to take the tin (not passivated with lead)

I have two industry leading customers that have specific requirements for components to survive 30 seconds above 230C. In one case I have a custom ASIC that is heat sinked on the die (to the PCB). The sink pulls heat out of the lead frame very effi

The SMTA is pleased to announce the program for the 2012 International Conference on Soldering and Reliability being held May 15-18 in Toronto, Ontario, Canada. Following on the very successful 2005 and 2006 International Conferences on Lead-free Soldering, and the SMTA International Conference on Soldering and Reliability held in Toronto since 2007, this conference will bring together the community of soldering and reliability experts. The event will be co-located with the SMTA Lead-Free Academy and the SMTA Toronto Expo.

The IPC Conference on Reliability: Assembly Process for a Reliable Product will be held November 1-2, 2011, in Irvine, Calif. The conference will address reliability issues that arise at the assembly level, dedicating half-day programs on new developments in each of three key areas: materials, processes, and test and inspection.

A designed experiment evaluated the influence of several variables on appearance and strength of Pb-free solder joints. Components, with leads finished with nickel-palladium-gold (NiPdAu), were used from Texas Instruments (TI) and two other integrated circuit suppliers. Pb-free solder paste used was tin-silver-copper (SnAgCu) alloy. Variables were printed wiring board (PWB) pad size/stencil aperture (the pad finish was consistent; electrolysis Ni/immersion Au), reflow atmosphere, reflow temperature, Pd thickness in the NiPdAu finish, and thermal aging. Height of solder wetting to component lead sides was measured for both ceramic plate and PWB soldering. A third response was solder joint strength; a "lead pull" test determined the maximum force needed to pull the component lead from the PWB. This paper presents a statistical analysis of the designed experiment. Reflow atmosphere and pad size/stencil aperture have the greatest contribution to the height of lead side wetting. Reflow temperature, palladium thickness, and preconditioning had very little impact on side-wetting height. For lead pull, variance in the data was relatively small and the factors tested had little impact.

As of today, the electronic industry is aware of the requirements for their products to be lead free. All components are typically available in lead free quality. This comprises packages like BGAs with BGA solder balls to PCB board finishes like HASL. The suppliers are providing everything that is needed. It is harder to get the old tin leaded (SnPb) components for new applications today, than lead free ones. So why has not everybody changed over fully yet and how can the challenges be overcome? A big concern in this transition process is reflow soldering. The process temperatures for lead free applications became much higher. Related with this is more stress for all the components. It affects the quality and reliability of the electronic units and products...
