Red Hot PCB: BTE Heat Sensor Arrays

By The MacroFab Team  |  November 7, 2017

Prevention, recovery, and return to work services are provided by a rehabilitation equipment business named BTE Technologies. On this week’s Red Hot PCB we have BTE’s beautiful Heat Sensor Array boards. These u-shaped circuit boards capture sensory data such as forces exerted upon the load cell, angle, velocity, and local temperature. The data collected is then displayed on the system’s CAN bus.

This PCB’s unique design allows servicing in the field without having to do extensive dismantling of the machine. This board is screwed into place so that it can simply slide around the shaft for maintenance. The design was made with the consideration that the slip ring might not work 100 percent of the time, therefore hold up capacitance was added for the power supply. There is a perimeter of capacitors on the inner diameter of the circuit board to hold up the power supply for several milliseconds just in case the slip ring were to lose contact for a moment.

Thank you to Justin Hiskey and Kevin Lamb for their contribution to this week’s post.
