Thick or thin gold layers - or is the colour the criterion?
If you want to deposit thicker layers of up to 10 µm, then a JE250 gold plating bath is the right choice.
If you only want to deposit thin layers of gold, but want to achieve a certain colour tone, then there are various coloured gold baths available.
Choose between the cold colour gold baths (these work at room temperature) and the warm colour gold baths (these work at 60°C).
