Electroplating is a straight-forward process with five steps:
safeTy preCauTions
Plating solutions commonly involve acids and other hazardous substances. these hazards can be mitigated with
proper planning, but they must not be taken lightly.
Read through the material safety data sheets for all chemicals used. MSDS’s for MG Chemicals’ products can
be found at www.mgchemicals.com/msds, where all of our MSDS are listed by part number.
Proper planning must be done to ensure that there is adequate ventilation in place prior to beginning the pro-
cess. a fume hood is recommended. at all times airborne concentrations must stay below the maximum allowed
levels listed on the related MSDS. When adequate ventilation is not available, use a half mask with a cartridge
suitable for acidic and organic vapors (available at your local industrial safety supply store).
Protective gloves and eyewear must be worn at all times, and a lab coat is strongly recommended because a
drop of some of these solutions will easily create a hole in clothing.
Ensure the workplace is a low traffic area and there is no chance of containers being knocked over or bumped.
CalCulaTinG The reQuired CurrenT
Before placing your board into the tank you will need to
calculate the amount of current required.
Start by calculating how much copper area you want to
electroplate on your board.
18 amps is required per square foot of copper to a
achieve a thickness of 0.001” (1.0 mil or 25 microns)
in one hour.
the current (i) required to plate a different area of cop-
per to the same thickness is directly proportional to this,
so i = (18 amps) * a /(144 in2), where a is the surface
area to be plated in square inches.

Example
What is the current required to plate a 5” x 3” board,
with the circuit covering approximately 40% of the sur-
face area of the top side of the board and 30% of the
bottom side of the board?
1. Calculate the surface area being plated
a = 5” x 3” x 40% + 5” x 3” x 30% = 10.5 in²
2. Calculate the required current
i = 18 amps x 10.5 in² / 144 in² = 1.3 amps
