Bertl_oO: why do you guys use OHS Park? The quality, timeline and price all seems worse then other people I've used...
01:17
Bertl_oO
what have you used?
01:21
mithro
Hackvana, Dirty PCB and a couple of other places I don't recall if the top of my head.
01:23
mithro
I've been the happiest with Hackvana (for the price / time / quality balance)
01:23
Bertl_oO
okay, let's do a comparison for one of our boards then
01:23
mithro
Dirty PCB have pretty crappy via, but when accuracy doesn't matter as much they are really quite cheap
01:26
Bertl_oO
I presume you have accounts at Hackvana and Dirty PCB, yes?
01:26
mithro
I haven't look closely at the spec - maybe OHS can do smaller elements
01:26
Bertl_oO
let's run the AXIOM Beta Main Board (v0.33) just for a price comparison
01:27
Bertl_oO
do you need gerbers or will eagle files do?
01:28
mithro
Is that 2 or 4 layer?
01:29
Bertl_oO
4layer
01:30
mithro
For the little expansion boards the minimum price would have been the same at Hackvana but I would have ended up with 3 times as many boards.
01:30
Bertl_oO
you are aware that the OSHpark prices are for three boards?
01:31
Bertl_oO
reading through the Hackvana faq, I see a few points which make it inferior to OSHpark
01:32
Bertl_oO
first, "reliable" shipping costs a lot, while international shipping is free on OSHpark
01:33
Bertl_oO
secondly, the Hackvana PCBs seem to be manufactured in china, which is against our fair labor, fair trade policy (https://www.apertus.org/opensource)
01:34
Bertl_oO
finally, OSHpark has high resolution silk on both sides, and high speed FR408 for the 4layer boards
01:36
Bertl_oO
I agree that the folks at OSHpark are not as flexible regarding board thickness or color (after all it's their signature) but in general we are very happy with the quality made in USA
01:37
mithro
Bertl_oO: OHS Park sent my boards through normal post without tracking? IE same as Singapore post
01:37
Bertl_oO
but they will redo + resend if you don't get them
01:38
mithro
Did your boards have horrible little burs were they have broken the boards apart?
01:39
Bertl_oO
not sure what you mean with burs
01:43
mithro
I'll take a picture when I get to work
01:43
Bertl_oO
okay
01:46
mithro
Using a new place you always wonder if everything is typical or not
01:46
Bertl_oO
of course
01:51
mithro
Hackvana has also helped me get quick PCB boards when I've been in a bind before, so I probably have extra favourable feeling towards him
01:52
Bertl_oO
that's okay :)
01:54
mithro
Always good to know your options :-)
01:55
mithro
Dirty PCB only wins on price really
01:55
mithro
I havnt found a cheaper option for small boards you don't really care about to much
01:56
Bertl_oO
also china based and "only" FR4
01:57
mithro
IE not the axiom motherboard :-)
01:57
Bertl_oO
yup
01:57
mithro
Great for little avr stuff though
02:02
mithro
Have you guys had any experience with PCB Pool at all?
02:03
Bertl_oO
yes, they are fine for larger quantities, but not competitive for small ones
02:05
mithro
I saw the Titan guys using them
02:06
mithro

02:07
mithro
BTW You have been using eagle for your hardware designs right?
02:08
Bertl_oO
yep
02:12
mithro
Shouldn't you be using kicad? :-)
02:12
Bertl_oO
yes, it is on our todo list
02:13
Bertl_oO
luckily eagle uses an xml format since 6.0, and conversion tools (not complete, but useable) to convert the designs to kicad are available
02:15
mithro
Kicad can read eagle parts libraries directly now IIRC
02:15
Bertl_oO
yep
03:52
Bertl_oO
off to bed now ... have a good one everyone!

morning folks!
11:19
Bertl
mithro: yes, the bridges between PCBs are normal, you can easily break them off with pliers and file the rest away in a few seconds
11:20
mithro
Bertl: I haven't seen them in ~5 years, so they kind of surprised me a bit
11:21
Bertl
yeah, I guess it saves them a lot of time not to remove them (which certainly helps with the price)
11:22
Bertl
v-groves as many others do are not really possible if you pack small PCBs together
11:23
mithro
Bertl: most places based in china seem to just do full routes and then manual sort afterwards
11:26
Bertl
OSHpark is not perfect, we discovered a few problems there during the quite long time we have been using the service now
11:27
Bertl
but it seems to be a good balance between fair labor and reasonable pricing with worldwide shipping
11:27
Bertl
nevertheless, as we provide all the necessary design files, you can still have it done at your favorite china fab :)
