I want to identify a SMD component of a Nubia Z9 MAX board (NX512JMB) In the next picture you can see the red square. A 4 PIN SMD component (or 2 PIN component, I don't know).

The green square I believe that is a resistor (like top component) or a capacitor.

This part of the board is the power connection. The components have broken because of a bad charger.

Nubia Z9 MAX

On the same board I found a similar component. The next picture show its label. || F1

Other similar component

I want to see that component (||F1) from the bottom side if it is similar to the missing component layout but I can't find it anywhere.

The F1 component is a diode, probably a zener in an SOD962 or SOD882 package. There isn't going to be a good way to find this part without the exact dimensions and the diode voltage.

The red square looks like what is left over from a WLCSP4 or other BGA part, without exact dimensions there is no way to be sure. Without the markings on the part it will be impossible to identify it (Could be one of these)

  • \$\begingroup\$ The red sqare is 1mm x 1mm and the green sqare is 1mm. (it is the smallest smd component, can barely be seen). \$\endgroup\$ – VasileM Aug 9 at 22:16
  • \$\begingroup\$ probably less than 1 mm \$\endgroup\$ – VasileM Aug 9 at 22:41
  • \$\begingroup\$ I would need the dimensions measured with a caliper to 0.2mm accuracy. It would be nice to know the spacing of the pads on the ripped off part. \$\endgroup\$ – Voltage Spike Aug 9 at 22:42
