Electroless Nickel on Aluminum for Solderability
I'm looking for a plating spec to apply electroless nickel to aluminum to allow soldering to the aluminum. In particular, what thickness range and phosphorus content works well? Thanks, Marty Albini Strategix IDMarty Albini

Marty, the thickness and phosphorus content really depend on the service life of the part. If you look at either the commercial or military version of the of the Electroless Nickel spec. Mil-C-26074 [link by ed. to spec at TechStreet] it will break down the various classifications. We have customers that like both high and medium phosphorus content coatings....the latter being brighter, faster and less corrosion resistant. Low phosphorus coatings are usually reserved for low resistivity applications. Contact a supplier of Electroless Nickel chemistry and they'll be able to give you some ideas this too.
