What is meant by Acid Trap?

Hi, What is meant by Acid Trap? how can be avoided? Regards,Girish

steve over 16 years ago

Acid Traps are generated when a gap from pad to trace is too small. They can be avoided by increasing the gap or moving the trace so that it exits the pad lower down the pad. Or you can use a gloss command to add a fillet from the pad exit.

Screenshot attached. I'm afraid you'll need Allegro Performance and above to do this with Gloss.
