E-nickel coating tolerance



(-----) 2006

I have a part that we manufacture the called out to be "Electroless nickel plated to spec 2404 .0003 thick" What thickness tolerance should I expect my plater to achieve. Plus or Minus ?

It really depends on the quality of the plating shop and the operator on that day, plus what you are paying for the job. Tighten the tollerances and you will pay more at most shops due to the increased QC.
Any decent shop should be able to hold a =/- 0.0001" on the parts. Size and geometry affect ease of handling, racking and processing which will have an effect of quality in most shops.

+- .0001" is easy, +- .00005" is doable.

You must expect that he will interpret an apparently open or vague specification in his favor. And that generally means less plate (less time, chemicals, labor, etc.).
It seems that the specification is what isn't up to the expectations.
