Thank you for the above information but what I want to talk about is the PCB design aspect. Should there be any warning about it in the DFM?

YES, the role of the drying cabinet is to protect those electronic components, so that there is no need to seal the electronic components. As long as you keep the drying cabinet working properly, your electronic components can be stored indefinitely

Take a photo of the other side of the PCB (not the front). It doesn't have to be RS232 at all - the connector is very popular.

Also didnt understand the jump from the 6th pin of the 2nd connector on the right side.

Sorry Michal I didnt get that. Do you think that they can be something else other than RS232?

Hi all, what may cause this things in attachments? Did it really rot as i thought? or it is something else.

Also, tried swapping the Servo card. X7 which is the Rising table servo motor card, swapped with X8,9,10 which are all the same and same result.

Those capacitors look totally fluxed. I can't tell if the last photo is showing a concavity or a blob of stuff. I think it is a blob of flux and contaminants. Does it burn off with a soldering iron?

Yes, that point remains unchanged. Just a general comment that there have been updates. e.g. re: desiccant re-use, certain devices no longer requiring bake-out, or bake times have been adjusted, and more.

It happened just after it came out of the reflow oven. And i guess the thing on the last photo is not blob of staff but the remaining part of termination of the cap. because when i try to iron soldering on it, i just cant. solders not sticking. on it
