And similarly, go to you big-box retailer, and open up all the mass market electronic items. Not just DVD players and TVs (ie, home electronics), but toys, calculators, timers, clocks, watches, CFL lightbulbs, power tools, dimmers, hair dryers, GFCI devices, pathway lights, keyboards, mice, etc, etc, etc. All of the items that are created millions in a manufacturing run are, if at all possible, done on a single sided PCB because it saves significant money over the entire batch. Yes, it's only pennies extra per board, but that adds up when you manufacture 10 million of them. The difference is negligible when you are only manufacturing a few thousand. But in terms of # of products produced, AND square feet of PCB produced, single sided certainly trumps double sided. Imagine how many $5 - $14 electronic children's toys or CFL bulbs are produced each day. -Adam -- http://chiphacker.com/ - EE Q&A site -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
