Overview
Sipm linear s14160 is an open-source printed circuit board by OpenSiPM, from the OpenSiPM/sipm-linear-1mm repository on GitHub. It is a 4-layer board of 90.8 × 68.9 mm with 209 parts on 139 nets, routed with 479 tracks and 202 vias.
It is built around the SSQ-103-01-G-D. Its parts include 98 resistors, 56 capacitors, 18 connectors, 17 ICs and 16 inductors.
Main components
1README
README.mdoverview
This repository contains a 16 channel linear array detector designed for hyperspectral fluorescense imaging. Each channel is composed of a single 1x1 mm Hamamatsu S14160 SiPM mounted in a carrier board. These feed into 16 pole zero filters and 16 transimpedance amplifiers adapted from the OpenSiPM single channel design.
pcb
The PCB is a 4 layer board that can be manufactured inexpensive (few dollars plus shipping) from a number of prototyping services. It could additionally be assembled with at least the passive components on relatively inexpensive, or it can be hand soldered via reflow. Aside from the Hamamatsdu SiPM, the components are stock at Digikey/Mouser.
Linear array bill of materials
power supply
The linear sipm PCB requires a bipolar power supply capable of powering the 16 OPA847 opamps, which have about 20 mA of quescent current each on top of any output current. This is supplied by the power-supply-linear-array project, which uses two sets of linear and negative regulators combined with a charge pump to generate the required currents.
Power supply bill of materials
bias generator
The bias generator provides the high voltage (~49V) required to bias the SPAD cells in the SiPM. Two versions are provided, a standard one using USB-C and a modified one with a second USB-C connector that allows connecting to an external USB-C power supply. This can be useful as the total array power is about 3W, and so exceeds the 2.5W supplied by USB2 devices. By using the second port, the power per port can be kept under 500 mA for hubs and hosts that are not USB3 or USB-C.

Questions
How big is the Sipm linear s14160 PCB?
It measures 90.8 × 68.9 mm and has 4 copper layers, 1.59 mm thick.
What parts does the Sipm linear s14160 use?
209 parts, built around the SSQ-103-01-G-D. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Sipm linear s14160 KiCad files?
From the OpenSiPM/sipm-linear-1mm repository on GitHub, at the commit this page was made from: the board is sipm-linear-s14160/sipm-linear-s14160.kicad_pcb and its schematic bias-control-lt8364-linear-two-usb/bias-control-lt8364-linear-two-usb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sipm linear s14160 design in my own project?
Its repository states no licence, so its author keeps all rights: ask OpenSiPM before reusing the design.
