Short answer

Standard Micro-Metallizer pens build up to 1.5 to 1.8 µm; heavy-duty pens reach 3 to 3.6 µm. On a 1 in² copper surface, a gold pen deposits about 0.5 µm in 2 minutes. Each pen holds 10 ml of solution and covers roughly 300 square inches. Operating voltage ranges from 5 to 12V DC depending on the pen.

Maximum thickness and coverage

  • Standard pens: 1.5 to 1.8 µm maximum
  • Heavy-duty pens: 3 to 3.6 µm maximum
  • Each pen: 10 ml of concentrated solution, roughly 300 square inches of coverage

Operating voltage by pen

Power comes from the Micro-Metallizer variable DC supply (110V/60Hz or 220V/50Hz input) or your own variable DC supply up to 12V at 0.1A. The part connects to the negative lead and the pen to the positive lead.

Frequently asked questions

How thick can brush plating get?

Standard Micro-Metallizer pens reach 1.5 to 1.8 µm. Heavy-duty pens reach 3 to 3.6 µm.

How fast does a gold plating pen plate?

About 0.5 µm in 2 minutes and 0.8 µm in 3 minutes on a 1 in² copper surface. The heavy-duty gold pen does about 0.8 µm in 2 minutes.

How much area does one plating pen cover?

Each pen holds 10 ml of concentrated plating solution and plates roughly 300 square inches.

What voltage does brush plating use?

Between 5 and 12V DC depending on the pen: 10 to 12V to degrease, 5 to 6V for nickel and silver, 6 to 8V for gold, copper, tin, zinc and palladium, 8 to 10V for rhodium and black nickel.
