Jim, Thanks for your reply. In your observations, why are there so many problems with this process. I am in the investigating stages, so Im trying to minimize my work. From what I hear from others, even the ones who support this process, that it is buggy. Where are people going wrong? Is it the customers fault for not following procedures, is it the equiptment makers fault for not making the equiptment right, or is it the chemical suppliers fault for not informing all the parties involved on what it takes to make this work. I realize with any new process there are some hurdles to encounter, but from what some of the people selling this are saying, it is a process that has wide acceptance. With this, I would assume some of the growing pains would have been overcome. Is it better in Europe or Asia? I believe this process orginated outside the US, so is the problem with the licencees, maybe not having all the info? I am a small shop, with little enginering support. Any info on this process yay or nay would be helpful. Thanks for your reply Richard Jim Kenny <[log in to unmask]> wrote: > There ar few if any true drop in processes out > there.
