+===== Mounting on PCB =====
+To reuse these in Arduino projects it is useful to have them mounted on a PCB.
+After disassembly the LCD's transparent light guide can be trimmed down to the size of the LCD:\\
+{{:electronic:lcd:dsc_0299a.jpg?400|Nokia 3310 LCD trimmed front}}
+{{:electronic:lcd:dsc_0300a.jpg?400|Nokia 3310 LCD trimmed back}}
+\\
+\\
+I have some spare Diymore Nokia 3310 adapter PCBs that can be modified to accommodate them:\\
+{{:electronic:lcd:pc094071b.jpg?200|Nokia 3310 adapter PCB top}}
+{{:electronic:lcd:pc094070b.jpg?200|Nokia 3310 adapter PCB bottom}}
+\\
+\\
+The four LEDs were removed from the top of the Nokia 3310 adapter PCB, and the capacitor on the bottom was replaced with a wire.  The capacitor was relocated to the Vlcd pin where it again acts as an external capacitor for the LCD voltage booster.  At this stage I have made no provision for a backlight.\\
