Hi Scott! Do your boards look like any of these pictures? http://www.stevezeva.homestead.com/files/Mousebites1.jpg http://www.stevezeva.homestead.com/files/Mousebites2.jpg http://www.stevezeva.homestead.com/files/Mousebites3.jpg http://www.stevezeva.homestead.com/files/Mousebites4.jpg http://www.stevezeva.homestead.com/AnnularRing.jpg http://www.stevezeva.homestead.com/AnnularRing2.jpg http://www.stevezeva.homestead.com/AnnularRing3.jpg -Steve Gregory- -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Scott Decker Sent: Thursday, February 23, 2006 1:34 PM To: [log in to unmask] Subject: [TN] Board etching question for you board shops out there. All you board gurus out there, I have a question for you. What are the reason(s) I see traces that look like a mouse has nibbled on the copper to etch it, as opposed to acid etching the copper? I'm looking at some boards that look like the resist was put on by a drunk with an old marker pen! The vias are not even round and the SMD lands have ragged edges also. This shop is off my list from here on out and going to be rebuilding some boards due to minimum trace problems too, but can anyone tell me what causes the ragged edges like that? I understand that specs are looking at averages, which means a high and low end of the spectrum. I think I know who put the low numbers into the pot. :-( Thanks for any info.
