We use "Pallets".  These are ESD foam backed with a rigid ESD material.
The pallets come in all sizes and shapes.  Some have sides, some are stackable.
The plus side to these is the visibility.  It's easy to see what's on them.
The downside -- They do get worn and dirty over time and there is a risk of
cross contamination with flux if not careful.  I suppose that's a risk with
anything that will be transported to a cleaning process. 

Totes can also be used where the boards can be slid in and out.  I've seen components
get ripped off the board if not spaced properly though.  The plus side to these is that
they have a cover to protect from dust, and, product may be shipped in them or stored.

Tray's are also an option.  The trays can be placed into rolling carts and moved around.  Again, the risk of contamination needs to be brought up.  The trays need to be washed periodically and should have a protective mat on them to prevent damage to "bottom side" components.  Trays are best for larger lots where the pallets mentioned above work well for us as we build in very small lots (4-20 boards/lot)

Hello Techneters,

I am looking for a new method to transport partially built assemblies in
WIP.

I would appreciate hearing how other people handle their products. If there
are any vendors out there, please contact me off-line.

I have already searched the archives, and there is not a lot of posts for
handling boards.

Thanks in advance,
