4. As shown in Fig.5, use screws with a diameter of 2.4 to 2.6 mm and a length of 7.0 to 10.0 mm
from the underside of the PCB.
5. Manual screwing is recommended. When using an electric screwdriver, optimize the parameters
such as tightening conditions to avoid mechanical damage. Check that the product is not
damaged after tightening. Also, the screwing speed should not exceed 300 rpm. It may result in
mechanical damage as shown in Fig.6.
