Bent PCB

Hi!
I would like to ask you if you also have a bent PCB in your M1 from the audio socket side?

The PCB bent phenomenon have been found randomly in our production process.
The PCB bent could be somewhat reduced by slightly loosening or tightening the screws.

I loosened the screws immediately and the photo was taken after that. Today the tile looks a bit better. Nevertheless, concerns remain about the continuity of delicate paths. Such a bent laminate can do a lot of damage.

Probably not.
The bent PCB phenomenon appears relatively frequently in the C1/C2/C4 series, and more than 500,000 units have been shipped, but we have not found any cases where the PCB bending problem has affected the operation/performance/durability.

Ok, everything seems fine with the M1. The plate returned to its normal shape after a few days. Hope nothing will happen in the future.
I think everything has been explained and I think that the topic can be closed.
PS. It's good for Hardkernel to think about some distances to prevent the plate from bending like this.
