About the OGK-SiPM-Board

OGK-SiPM-Board is an open source PCB design by vikulin, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 36.5 × 36.5 mm, with 15 components from 8 distinct parts.

Other key parts include the TPS7B6950DBVR and MICROFC-60035-SMT-TR1. By type, the board carries 5 capacitors, 5 resistors, 2 ICs and 2 transistors.

It belongs with the sensors designs in this gallery.

From the project

🖸 OpenGammaKit PCB module designed for the 6 mm C-Series MicroFC-60035 SiPM in KiCad

This carrier board is designed for the 6 mm C-Series MICROFC-60035-SMT silicon photomultiplier (SiPM) by onsemi. It was developed specifically for the OpenGammaKit detector, but it can also be used in other systems. An optional circuitry for automatic SiPM temperature gain compensation is included.

On the front side, only the sensor is mounted, while all supporting components are placed on the back side. This layout provides optimal optical coupling and ensures light-tight sealing. The unused SiPM pin 4 is tied to the ground pad, adding thermal mass and connecting it to the ground plane…
