Well ..... coping and pasting something doesn't make it

Memory retention and comprehension is key,
so I'll not address the trolling part
-since I am a fisherman and *DO* troll :-)

My point was, determining a "cold solder joint" takes
quite an expensive piece of equipment.

Not really when it comes to just a regular solder connection. On a
multi-layer PCB it is a different matter. You need a special diagnostic tool
for each and every compnent of the board. A bit too expensive for any
average home tinkerer and PC shops. They RMA instead of test these types of
problems. Can you imagine the cost of just a piece of equipment to test a
DDR socket? Not only do you have to read resistance at rest, you must read
it in every state that the DDR may be in during all cycles. Kinda like
running Memtest and reading the resistance across all the connectors at the
same time and then determining where the bad solder joint is.....:-) "Cold
solder joint" in this case must be used instead of "broke".......:-)

I'd be willing to bet that major motherboard manufactures,
i.e. Abit, Asus, etc. etc., do not manufacture the actual PCB,
but rather has a company such as Jabil
http://finance.yahoo.com/q/pr?s=JBL make them to their specs,
the same way Sears does with a wash machine. Thus, Abit
or whoever ... they would not have the necessary equipment
to check for a cold solder joint, let alone JANA!

I would think that since many have different board layouts, that it is still
quite probable they have individual contracts with PCB vendors. I have
noticed that, in some cases when problems arise, the same problem may affect
only certain manufacturers and not all. That seems to point to several
vendors making the boards.
