This is an old topic, but keeps coming up. Solderability and reliability issues with SMT gold plated terminations when used with tin/lead solder paste/hassle finish PWB. I need to know which standard (mil, IPC, J-STD??) tells you all about the probl

Well, if it "keeps coming up", let's take a pass at keeping down. For: * Requirement that gold be removed from components, pads, etc. is J-STD-001C, 5.4.1 * Context of that requirement [J-STD-001C, 5.4.1] and 6 or 7 references are in IPC-HDBK-001.

Interconnection technology relies very heavily on the ability of the conductors on a printed wiring assembly to maintain reliable signal integrity. Harsh environmental factors can precipitate a loss of conductivity due to oxidation and corrosion. Connections are typically soldered or inserted using pressure fitted connectors to obtain enough surface contact to meet the electrical conductivity requirements. In pressure contacts, surface integrity is especially critical where the abrasive effects of retraction and insertion can wear off the metallic finish from the contact area. This can expose the underlying copper or nickel and lead to increased resistance at the contact points. These types of conductors are frequently found in card edge connectors where the terminations are plated with a layer of nickel and gold (frequently referred to as gold fingers). A hard gold is typically used containing very small amounts of nickel and cobalt to increase the wear resistance.

There are many things that can go wrong when soldering to gold plate over nickel surfaces. First of all, we know that gold and solder are not good friends, as any time solder comes into contact with gold, something seems to go wrong. Either the solder bonds to the gold and eventually pulls off as the tin and gold cross-migrate, leaving voids; or the solder completely removes the gold and is expected to bond to the metal which was under the gold.
