Immersion gold VS gold plating

Posted:05:56 PM September 13, 2021 writer: G

The distinction between immersion gold as well as gold plating


Gold plating: Gold plating is an approach of transferring a slim layer of gold onto the surface area of additional steel via the layering method. The gold fragments affixed to the pcb, as solid bond likewise referred to as tough gold. The gold finger of memory financial institution is tough gold as well as abrasion immune.
Immersion gold: Immersion gold via chain reaction to make gold bits connected to PCB. As a weak bond, it is likewise referred to as soft gold.


Why utilize gold plating?


As IC comes to be increasingly more incorporated as well as IC pins are additionally denser. This brings problems to SMT positioning. Additionally, the life span of the HASL board is really brief, so the gold plating board addresses these issues:
Nevertheless, as the circuit lines end up being denser as well as it brought short circuits. And also as the regularity of the signal come to be higher, the result of the skin that impacts signal top-quality comes to be much more evident.
Skin impact: High-frequency rotating existing, the current will certainly have a tendency to focus on the surface area of the cable.


Why utilize immersion gold?


In order to fix the above issues of the gold layering board, so take on immersion gold modern technology:

  • 1. As a result of the distinction of crystal framework in between Immersion Gold and also Gold Plating, Immersion Gold is simpler to bond than Gold Plating as well as will certainly not create negative welding. The stress and anxiety is extra convenient to manage.
  • 2. Because just pads have nickel-gold, the signal transmission in the copper layer in skin impact and also will certainly not impact the signal.
  • 3. Difficult to oxidation.
