Gold thickness in immersion gold board is more than that in a gold plating board. Immersion gold board is more yellow than a gold-plating board, that’ because gold-plating board has the color of nickel. 2. Their crystal structures are different. Comparatively speaking, immersion gold is easier to be soldered with less poor solder issues.
Gold-plating thickness is a critical and often misunderstood tenet of gold soldering. In gold soldering, the physical bond is between the underlying nickel layer and the solder itself, with the gold layer serving as a barrier to help maintain the solderability of the nickel layer.
