Electroplating a thick layer of gold on copper

Dear sir,

As I wrote, I am a Msc. Student. I need to electroplate a thick layer of Gold on copper, about 60 microns thickness it should have. But I only could gain layer of 10 microns in using Cyanide free bath. Now I would be very grateful if any body could help me with my problem. I look forward to hearing from you as soon as possible.

Regards,
