Probably 10 years ago our boards were predominately HASL leveled tin/lead.
We performed a Taguchi experiment with one of our suppliers and were able to
optimize the process so the thickness/height and the shape of the height.
We were able to optimize the controls and establish a spec. Most all our
boards now are Ni/Au for SMT. We also found that by performing the Taguchi
we were able to do all this in probably 4-6 weeks. Most of that time was
planning, travel, and confirmation. Our supplier worked with us on the
project and the result was a win-win for everyone involved, ITT, the
supplier, and the ultimately the customer. A well planned Taguchi or DOE
would allow you to optimize your process in a timely manner.
