nothing its the same....What's the difference between hekate 4 vs tumGer's hekate 4?
Thanks! I am still on the fence about how to best do the connectors. I have the footprint on the solder stencil, so I did one batch by pasting and sticking the connectors on before placing. Then I did another batch soldering by hand. I'd say they were about equally challenging, each needs a bit of finesse.
They're tricky little buggers, even the good ones. How do you get both sides of the connector in the oven? I assume there must be an easy way since you can find pre-soldered ones on Aliexpress for almost nothing.
Out of a good 10 I hand soldered, I accidentally bridged multiple pins on 2 of them, which proved to be near impossible to fix. Another one just wouldn't seem to weld D+ and I ended up de-laminating the pad after several tries and a good deal of liquid flux. Kicked my sense of pride right back down after feeling good about drag soldering the ATSAMD21 pretty easily.
I have no idea if it's going to work, but my new plan is to switch to a 0.8mm board thickness (up from 0.6mm) as that seems to be what the connector was designed for, and hope the liquid flux and surface tension does the rest of the work for me. I decided to make a new footprint with some bigger pads to help with this. Doesn't look pretty, but if it works I won't have to touch the pins themselves and if it saves time so be it. Hopefully it cuts out some tedium! Let me know how ugly it is.

Ideally, the oven should be great - paste both sides, pop on, and bake. Problem is that my stencil doesn't release well at this teeny pitch and I have to touch it up manually. Maybe I'll get a thinner stencil someday, but for now I'll make it work.
0.8mm is what mine is sized for, although it said 0.8mm copper to copper so I've wondered if that meant 0.6mm board or what. It seems to work OK with a 0.8mm board, though so I've no complaints there.
Is D+ the outermost corner pin on the atmel? That damn pin gave me a lot of headaches at first, just didn't want to connect on the fist few boards. I ended up pressing the parts down a bit harder to make sure it wets with solder properly, now it seems to work pretty well.
I love your modified footprint for the C type, that is a freaking brilliant idea. Little bit bigger, with a nice reservoir dot and missing the useless no connects - I think it looks great!
I've never actually seen the inside of a PCB oven. I kind of assumed it was flat and that the connectors would end up resting on the bottom, pushing the board up. A quick trip to Google just let me know how wrong I was.
That is indeed D+, first pin from the top on the right side of the chip. I haven't actually had any problems soldering the chip itself (besides not being able to hold my breath for very long), just the danged Type C connector.
Thanks for the kind words about the mutant footprint! Hopefully the theories behind it pan out.
Let me know if you want me to modify the case I made you for V2!
Use chainloader...It seems like ReiNX has been updated with a new payload... could we get a precompiled firmware for it by chance?
