hi again, this is a good point. maybe the acid trap being referred to is something like a pth that is improperly tented. a second point. when i previously replied ...'if the fabricator doesn't care'... i was careless myself. i should have said that 'if after running a couple of design rule checks and found nothing wrong...'. sorry about that. phil -----Original Message----- From: Howieson, Rick [mailto:[log in to unmask]] Sent: Monday, May 08, 2000 1:30 PM To: [log in to unmask] Subject: Re: [TN] What is an acid trap? Hello, I can't see acid being trapped around traces, unless the fabricator has extremely poor rinses, however I've seen solution trapped in holes where a designer requires the holes to be plated shut.
