AgENIG (electroless nickel and immersion gold plating over thick film silver) substrates reportedly offer performance advantages when using Pb-free, higher temperature solder required for RoHS compliance.  Are said to eliminate solder leaching; enable processing up to 260°C or higher; permit multiple SMT reflow solder cycles, touchup and repairs. Are suitable for assembly types including SMT soldering and die attach. Addition of a thin layer of palladium plating permits gold wire bonding and eutectic die attach. Products can be used up to 170°C continuous operating temperature. Pattern definition can be held to 0.006" line and spaces.

WonderMask PX temporary, peelable, latex solder mask reportedly dries in half the time of other solder masks. Is hand applicable and withstands fluxing, wave soldering and cleaning operations. Is said to effectively mask and protect open through-holes and underside components in wave soldering processes, withstanding temperatures up to 650°F. Can be used as a conformal coatings mask. Has strong tensile strength when fully cured, and peels easily, even under harsh conditions.
