There are no screw posts between the PCB and the plate, so it is recommended that players assemble the keyboard with foams, using the switches to fix the PCB and plate.
We need to give players an early warning that even without assembling any bottom foam and using the PCB Gasket, the Ep70 still has a relatively stiff feel. Meanwhile, since the distance between the inner shell bottom and the bottom case is quite close, the room for depression is also minimal, so players who prefer a soft and bouncy feel need to be aware of this. The sound performance is also a matter of personal preference, but it is safe to say that it is not at the top tier level, so players who are particular about the feel and sound need to take note.
Of course, we still recommend that players configure at least 1mm of bottom foam at the bottom to prevent the PCB from sagging and contacting the metal bottom case, causing short circuits or other issues.
