Not only that, if there's any moisture in the PCB it may turn to steam when you pass it through a reflow oven and tear up the PCB.

Sure, in this case the result will probably (hopefully!) be a test fail. The normal test would say "GFX BOARD FAILED" and we know that already, thanks. But the FE tests are verbose so if it fails e.g. a bitplane memory compare test you know where to start looking.

I always run the diagnostics over a serial console, so I can capture the output for future reference. That and a sticker on the ESD bag with test date / result / part# / serial# so I can always look up what happened and what the status of a part is. This is part of my long-term goal of reducing my spare parts to a set of known good parts, relevant to the systems I own.

My point was that one cannot even read the text. Biggrin
