Immersion gold electrolyte for ENIG
Gobright® TLA-77 is a special neutral immersion gold electrolyte. It is suitable for ENIG plating on PCB and ceramic substrates. The gold concentration in the electrolyte is just 0.4 g/l. This means a dramatically cost saving potential by reducing dragout gold volume. This process also has excellent solder joint characteristics due to its lower corrosion attack on electroless nickel.
The electrolyte needs one concentrate for make up and an additional component for replenishment.
