Looks like the post office is dong their typical bang up job of delving my pcb of this ;) In the meantime - any prelim parts list for this yet?

AWESOME - I happen to have a BTDR-3H just laying around waiting for this pcb!!

Thanks - I get that. I mean there should be direct connection to the ground pads (circles) with no thermal pad relief like in a normal ground thru hole pad.

Thanks - am I right in assuming that there are no thermal isolation pads on the top surface (to ground)? that the solder mask is what "borders" the pad for the bga package?

Its an LTM8054 for a stepper motor driver (not my selection, not my choice.)

Thanks - appreciate the tips. I think I have a strategy - now trying to understand BGA and its requirements, therma vias, etc.

So I'm doing a surface mount board for the first time. I've done a few dozen though hole projects, etc. It's going to require a different strategy I guess! In my through hole designs it sure is nice to have the option of FRONT or BACK (2 sided board) due to the nature of "through holes"...

I'll never do etching again.... its not just the etching, the drilling, cutting, etc ughhh. The pcb software (I've used Kicad) takes a bit to get used to but with a bach of 5-10 small boards for ~$10shipped (pcbshopper) I'll never do etching again. May take awhile to get em, but saves me a ton...

options 1) photoshop it, print it on transfer paper, iron it to bare PCB, etch PCB, drill PCB. Several hours, lots of work - outcome depends on how good you are but will probably look like crap. alternately use a sharpie on the PCB and then etch. old skool style! 2) point to point on perf...

they dont really "cut" very easy btw. File - maybe a little, just be careful of the "dust" (dont breath it) Make SURE there are really no traces for you you damage- they can be pretty small, and covered by the solder mask. I think most of these are double sided tracks, but there's usually one...

I know way off topic, but the forum has a really nice clean look to it. Is it custom or opensource or ??? I used to do websites but that was AGES ago. I'm probably pretty far behind the times....

looks like a cool pedal to build - any place (USA) that you can get the V3207 though??

just thin 0.040"-0.,060" cut and polished aluminum with clear waterslide decals and clear coat.

yep - huge holiday everything shuts down

I honestly didn't have enough time to really compare before I got lazy and just installed the VTL. They're nice but hard to find. I had some left over so though might as well just go with them and be done with it. The Aion Electronics version of the compressor specified them vs making a...

This might be interesting - but sounds like your's is working fine I tested a bunch and just wound up going with VTL54C that I had left over. https://forum.pedalpcb.com/threads/what-green-leds-for-general-tso.2729/ Very cool!

thanks - I thought the "B" might be ok but wasnt sure. Tayda has those.

Need a bunch of BC560C (not B) for a project(s). Mouser/Digikey are phased out (they have the BC550C) and tayda has the BC560B. Any sources that are reliable? Looking for about 40-50 parts. There's China - are these likely counterfits or too cheap to bother...

keeping my eyes peeled.....
