Tenison, The cost to build may very well remain the same, it would depend upon the amount of process controls in place at the fabricator as well as what type inspections/testing are currently being performed on that type product. You may find that many fabricators are capable of providing product that meets the requirements of class 3 and not even know it. Keep in mind that the testing/acceptance criteria is far more critical for a class 3 then for class 1 but that does not mean your current fabricator, or any fabricator may not already be performing those added process or inspection steps today. The extensive testing often required of class 3 is often the price changer... I'd ask your fabricator what their thoughts are... Franklin D Asbell Network Circuits, Inc.
