Hey guys, I need any tips you have learned on immersion gold plating using Caswell's 24ct gold plating solution and 24ct gold anode (or using the S/S anode).
I have Caswell's manual (version 4) however, would like some first hand information/tips from anyone who has been doing this for awhile.
I have been nickel plating very small electrical contacts (about .125 to .250 Sq. In. in surface area) for the medical company I work for.
This is a "no brainer" job for me and have been doing it for years.
Today I was approached about the possibility of gold plating them (instead of nickel).
Reason? These new contacts will be in a highly magnetic environment (used in an MRI bore) which dictates not using any magnetic material, thus no nickel permitted (will show up as artifacts on MRI films) and the production plating company wanted $160.00 each to gold plate them in the small quantities and fast turn-around that we require.
I will be immersion plating them on a small electrically charged rotating hanger rack which holds (6) contacts each.
Anode: 24ct gold (for now at least, let me know your thoughts using the S/S anode)
Base Material: Beryllium copper.
Part area: .18 Sq. In. (each contact)
No nickel strike coat allowed since they will be used in a MRI bore.
Total quantity of parts to be plated: 24 pieces.
I already have the P.O. cut for the gold solution and anodes from Caswell, will be ordering the supplies on Monday and need any info fast since these must be finished by next Thursday (Feb. 17th).
