However, the gold layer should be as thin as possible to avoid issues like gold embrittlement and reverse corrosion since gold is a non-reactive element during soldering. But if the gold layer is too thin, it won't fully cover the nickel layer, which can lead to oxidation and soldering problems if the board sits in storage for too long.
