We agree with Russ that you're talking palladium instead of platinum. Your wetting problem likely is not the Pd-Ag surface layers, but the underlying metal or nickel to which you need to wet. Either a base metal is: * Contaminated and poorly wettabl

Agreed. In my experience you will not wet solder to: Platinum Iron Constantine Tungsten Carbide titanium Chromalloy allomega alloy 303, 304 ...and the list goes on and on. You will either need to weld or braze. These are high temperature prcesses

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.
With the Spectrum II's new Precision Z-axis, smaller dots and thinner solder paste lines can be achieved. This capability is standard on all Spectrum II systems and replaces the Precision Z option on the older Axiom products. In order to achieve su
