Hi, That's good news, and we did outs with SN100C as well on Wed, however we are still working hard on getting a good profile. We have some large BNC connectors, and they are hard to profile. We also have wave palettes, and these might be too thick

If the only difference is the layer count, check the profile as stated above. If you dont have a profiler you can probably get the local Kic or Mole rep to do a demo on that board. I believe I was the one who stated in an old post that prying the lea

Hi, Thanks, and we are doing that today. After spending the day playing with all the usual things that used to work, we are focusing today on profiling and data to get things right. The only worry I have is did we get a wave that can handle this, a
