The SMD only kit includes the PCB and all SMD components (ignoring NRF, I have no interest in that), yes?

That would be SO HELPFUL! :smile:

No it includes only the BOM as some people already have pcb’s

Does the silicon heat transfer pad on the aluminum heat sink work as well as an all aluminum heatsink?

You cannot have an all aluminum heat sink because the Direct fets are conductive

Awesome, payment sent :smile:

Never done SMD soldering before but my brother does it for a living so I’m just going to treat this as an expensive experiment and see how I go :yum:

Could you provide the stencil files, so we can order them in advance?

@bimmer do you have a link to a video or tutorial on how to solder the DirectFETS? that is the only part of the BOM that I will have problem soldering as I am unsure how to solder those FETS on.

Learn but with your brother standing behind you and with his equipment, I’d love to have that assurance…zero losses

I’ve got the gear but no Yoda to help me, I expect losses even catastrophicIMG_8698

He doesn’t actually own the equipment, his work owns it. I’ll do the work myself but I’ll get my brother to show me the best way to do everything. It’ll be fun.

Hey the supported surface didn’t turn out great but this is basically it with some tweaking I bet it could be nicer.

Is there a type of filler, like if it was wood you’d use wood paste, does this have something similar that could be used to refine it?

I think it turned out pretty good for the first attempt! Thanks @bimmer! :slight_smile:

I printed it at 150mm/s with low support. So maybe if I print at 60mm/s with max support it’ll look better
