Never run boards through a dishwasher!
This has got to be one of the most insane ideas I've ever heard.
Commercial PCB's do get washed, but only after the water has
been deionized with some rather expensive and high maintainance
equipment.
I'm quite sure that manufacturers don't go through the expense of
maintaining
this gear if your maytag washer could do the job.
Actually, the IBM Interconnect Manufacturing Process Development Lab uses
a Whirlpool, not a Maytag.
Lots of domestic water supplies have 'hard
water' and.or high mineral
content
that will dammage or destroy your boards. Maybe not while they are in
the
washer, but corrosion may set in later.
I'm sure that filtering the water wouldn't hurt, but even DI water will
damage your board if you don't remove it from the board quickly. I.E.
don't air-dry the board.
