Jami, what the original post implies is that the fabricator had some issue with being able to etch the board in a manner that met the specified requirements. Those requirements have not been spelled out for us, nor do we know the limitations or concerns of the fab shop. Therefore we are discussing this topic theoretically which can tend to exagerate the discussion.
In short my comments would thank the fabricator for being honest and showing integrity for whatever reason they felt that they couldn't fabricate the board as is. There are all manner of fabricators out there, I know I have run into all the types over the years. Some have tight controls, some have virtually no controls. Some have plastic tubs of etchant, some have no aggitation, some have bubbling to aggitate etchant, some move the boards through the etchant and some use spray etchers of all descriptions, some have completely automated lines. Some do your boards alone in the tank, some do 5 companies boards at a time in the tank. Maybe that is where the problem lies but we don't know for sure. We can just be thankful that this fabricator shows minimal integrity in admitting that they felt they could not fab the board as it was laid out. That is not a problem with the fabricators etching methodology, it is a limitation that they acknowledge. A major asset in a board shop in my opinion. Sincerely, Brad Velander. -----Original Message----- From: JaMi Smith To: Protel EDA Forum Cc: JaMi Smith Sent: 08/10/2002 7:53 PM Subject: Re: [PEDA] OT - Complex boards and time to Layout? <snip> What I am saying, and what I have always said, is that the statement in the original post implies no agitation / circulation / replenishment, and that IS a MAJOR problem. Do any of you guys actually dissagree with that?
