Mounting holes for SMC connectors seem too large, but aren't
The 5 mounting holes for soldering the SMC connectors seem too large.
There is quite some space and they can move a lot when not yet
The hole size according to the PCB design are 1.7 mm (x4) and 1.2 mm (x1), which is precisely the same according to the datasheet of the connector (of 2 brands). So there should be no problem. But it still may be difficult to get the front-panel assembled later.
Verify with DEM quality office.
Maybe add assembly instructions (mount front-panel before soldering)?
