Last night I locked myself out of my apartment and while waiting for my boyfriend to come over and let me back in, I spent the time pacing around the backyard and alternately cursed myself at my stupidity and thought about some specs the boss wants me to help write. Well, my brain works in strange (and wondrous) ways and I began to ponder something...... Would applying a gold plating to your component pads affect the electrical spacing required? IPC-2221, Para 6.3 and Table 6-1 do not mention board materials or any plating notes. Does this mean that it doesn't matter? Like I said, it's probably a silly question but I honestly don't know the answer. It *seems* that it would make a difference but I can't find any data to indicate what that difference would be. Would some kind soul (and there are MANY here at DC) care to enlighten me? Thanks for all of your help! JoAnn L. Amerson Design Librarian Red Lion Controls, Inc.
