I could not find much info on their aluminum PCBs, though the info from their competitors indicated that they did insulate and plate PTH on aluminum boards, so I assumed the same of this one. I'm not knocking this manufacturer - I've had good luck with their 4 layer FR4 boards, and even PCBA of moderate complexity. But they are bargain basement, so I'm not surprised about this outcome. | |

I'm no stranger to SMT, but I guess I mostly think of SMT being useful for small signals. This board is a current rectifier and voltage clamp, and will be inserted between a power supply and a large stepper motor driver. On the board is a schottky, a zener, a resistor, a capacitor, a MOV, and two terminal blocks. I'll look into SMT alternatives, though I may just fall back to FR4 - after all, it's just a nominal current of 3A-5A, though components are spec'd for 10A. | |
