Intro

If you're thinking of making your own aluminum board (Al) here is my example of the custom aluminum LED panel with powering from the surface-mounted USB-C and additional temperature sensors (NTC thermistors) to measure actual operation temperature (investigation purposes).

Work Demonstration

Board could be powered from the any USB-port by using 5V3A charger and USB-C cable:

Because it has 5.1k resistors on CC1 and CC2 pins it could be used with PD chargers. Additionally each input has PTC (resettable) fuse 5A:

Additional Feature

This is a not simple LED panel because the board has footprints for temperature sensors. It's possible to install digital I²C sensor SHT30 or analog NTC thermistor in 0402 or 0603 package, which could be used for precise monitoring of the operational temperature, which important for LEDs.

I decided to use NTC sensor 0402, so for better measurements it's covered by the heatsink glue (paste) for better thermal contact:

Conclusions

• Making simple aluminum boards it's almost the same as 1-layer board without vias and components on the bottom side
• You can use most of standard SMD components with aluminum boards
