Due to the stainless steel material is provided with a series features such as excellent corrosion resistance

and form ability,compatibility,and robustness within a wide temperature range, it is widely used in industrial,

electronic, supplies, and building decoration industry areas.

1.PASTED TO THE CONNECTING FIGERS TO STIFFEN THE FPC strength in order to facilitate assembly.

General thickness is 0.2mm

2.Adding a steel plate to the bottom of the main keyboard for positioning and to ensure a nicer touch. Thickness

is about 0.4mm
