I opened a two product boxes which are similar and have PCBs. The PCB in one box is gold plated. Can anyone explain why it needs gold plating? Thanks in advance

Assuming you are talking about solderable surfaces: People specify various materials to protect the solderability of the pads on the board. Gold, actually, Electroless Nickel - Immersion Gold [ENIG], is popular. * Board fabricators like it because

The gold plating on PCB has a 40% higher resistivity, and it is much more expensive. So gold is not used instead of copper for conductors. Last month I purchased some PCB from Cplfpc and Greatpcb.

What is the use of gold plated boards?

1. To protect the nickel and copper under gold plating from oxidization before soldering. Gold plating can extend the PCB self-life and improve the solderability for 2nd re-flow. 2. Provide a good bonding strength. For Chip on Board process that Gol

Flatness is only half of the advantage. Gold doesn't corrode. There are other flat surfaces but do not last as long as gold.

Back in the 50's, 60's and 70's gold plated boards were all the rage for high reliability. test equipment, milspec etc. Nowadays only edge connectors are gold plated. Immersion plated gold is also used but it doesn't last the distance like gold plate

We've made the decision to move towards Gold Immersion on our PCBs to eliminate flatness issues with QFNs and BGAs. Land/component pad geometry, population density, and other factors, have made it necessary to ensure a near perfectly flat surface tha

I'm not 100% sure which type of gold you're asking about, but if you're talking about hard gold plating, I think the most common use is to provide a durable surface for things like membrane switch contacts because it resists abrasion and other mechan
