Tiny MicroFC SiPM Carrier Board
Tiny carrier board for a 6 mm C-Series MICROFC-60035-SMT silicon photomultiplier by onsemi designed specifically to work with the Open Gamma Detector, but can be used with any other system.
PCB size is 10 x 10 mm. The solder pads for the SiPM are slightly bigger than they need to so that you can easily hand-solder everything! You can buy all the parts and the PCB using Kitspace or do it on your own as well. It is advised to panelize the design if your manufacturer of choice adds an extra fee for the small size if you want multiple pieces.

This ensures good optical contact and light-tight sealing.
The PCB includes an RC low-pass filter that is optional to use. Use it by mounting the two 0603 components, then soldering wires to the VCC and GND pads respectively. The SiPM signal will then be the anode A pad. Do not solder anything to the cathode pad in this case.
If you are connecting straight to the SiPM, do so via the cathode C and anode A pads. You do not need the GND pad in that case.
