Who would be interested in a blank pcb for Georg Braun's new A1000 system (Eagle)

[Kristian95]

I'm trying to figure out how many people would be interested in buying a blank pcb for the Eagle system developed by Georg Braun (http://www.gb97816.homepage.t-online.de/)
We'll need to have an idea of the number of people interested before it is possible to get accurate price offers for the board.

I have posted an identical thread on Amiga.org... please only show your interest in one thread

This "CF-Adapter für das GB A1000 Mainboard" looks Mega!

[Kristian95]

I checked out this place: http://www.pcbfabrication.com and the prices are pretty good!
If I figured it out correctly (I am quite sure I did!) the price for 1 board is:

1 board: us$ 360 per board
5 boards: us$ 168 per board
10 boards us$ 106 per board

Does anyone have any experience with this company? Also I'd prefer if someone who knows these things inside out can help check out I did get the right quotation...
Here is what I filled in:

4 layer board
Single board with 1 board per panel
board length: 317 mm
board width: 342 mm
peelable soldermask: both sides
solder mask: 2 sides (blue board)
silkscreen: 2 sides (white)
minimum trace/space: 9-10 mil
minimum hole size: 17-18 mil
electrical test: yes
material: Fr4
board thickness: 1.6 mm
finished copper weight: 35um for top, inside and bottom layers
board finish: hot air solder leveled
stencil: none
blind via hole: no
controlled impedance: no
buried via hole: no
controlled dielectric: no

Please, please let me know if these are all the correct settings... I am only sure about the dimensions and material.

I would be interested if it's less than 120$. Custom chips can be found, but you also need to source someone who can do the GAL programming, I think that board had lots of GALs/PALs. And the zorro2 slot of course.

I would be interested in the latest revision bare board if it comes in around $100.00.

[Zetr0]

Depending on funds at the time, i would be interested in an board around the $100 too,

If anyone needs help with the GAL programming i have programmer and will post global lol

it is a shame that i dont have the full version of eagle as i would replace most of the gal's / pals and glue logic with a couple of CPLD's would make a much smaller board too...

hmmmmmm

[Kristian95]

sounds good Zetr0... when the day comes I might just be a customer for some GAL programming

[Kristian95]

Ok I have now gotten a few things sorted out by contacting Georg
The following parameters should be correct:

4 layer board
Single board with 1 board per panel
board length: 317 mm
board width: 342 mm
peelable soldermask: both sides
solder mask: 2 sides (blue board)
silkscreen: 2 sides (white)
minimum trace/space: 7-8 mil
minimum hole size: 11-12 mil
electrical test: yes
material: Fr4
board thickness: 1.6 mm
finished copper weight: 35um for top, inside and bottom layers
board finish: Gold plated (electroplating) or ENIG (electroless nickel gold)
stencil: none
blind via hole: no
controlled impedance: no
buried via hole: no
controlled dielectric: no

With these parameters the automatic quote from the site is:

Gold Plated (Electroplating):
1 board: $ 648,51
5 boards: $ 196 per pcb
10 boards: $ 124 per pcb

ENIG (Electroless Nickel Gold):
1 board: $ 586,88
5 boards: $ 175 per pcb
10 boards: $ 110 per pcb

I have also sent the blue prints for the board to get a "final" quotation from them, but I think these should be pretty close to what we can expect.

Again, please PM me if you are interested and let me know the maximum price you are willing to pay. The more pcb's we order, the cheaper it'll end up being for all of us

I have GOOD news

I have reached 2 companies that will accept the Eagle files (which will make it the companys problem to make a working gerber file).
And even better, the price per board is very good!
I also got a quote from the company in Germany which Georg used. All three companies use gold plating finish. I will show the quotes below for comparison (all prices are per pcb):

Spemco Teoranta (Ireland):

1 pcb: €481,28 (+€100)
5 pcbs: €129,49 (+€20)
10 pcbs: €83,07 (+€10)
20 pcbs: €59,93 (+€5)

for all orders (no matter what size) it will cost €100 for tooling setup (shown in brackets as cost per board above).


custompcb.com (Malaysia):

10 pcbs: 38
20 pcbs: 33

This price will be adjusted as gold plating has to be added.


E&K leierplatten (Germany):

1 pcb: 805,29
5 pcbs: 317,14
10 pcbs: 221,46
20 pcbs: 185,63

This is by far the most expensive, but we know for fact that these boards work.

If anyone has any experience with the above mentioned companies, let us know

This far I have received 7 pm's (at Amiga.org) showing interest (only counting the pm's for simplicitys sake).

[lopos2000]

I am very interested if the price is right. Count me in.

[Kristian95]

super! The more the merrier one thing to remember is that once we get as far as ordering is that I'm in the US and all the boards will arrive here, which means shipping from the factory to me as well as shipping from me to the end-user will have to be added, but it shouldn't be too bad

[Zetr0]

hmmm i couldn't get a website for custompbc.com

Because of the typo...

[Kristian95]

hehehe exactly zipper sorry Zetr0, it is custompcb.com not custompbc.com ups! I edited it in the post now.

[Kristian95]

Ok this is the list of people who are definately interested (Amiga.org users):

Tron2k2, Jeff, mdivancic, skurk, damiraga, trekiej, amigadave, firedawg, TheGoose, Bandis
= 10 people

I have spoken to da9000 (Amiga.org user) and he is interested as well (=11)

I myself would want one as well (=12)

People from EAB who are interested: coze, Magic, Zetr0, lopos2000 (=16)

People who might be interested:

jkonstan (Amiga.org)

Ok, people, if you are interested, and not in the list, please either pm me or quote this post, adding yourself to the list and updating the counts. Remember, the more people ordering this board, the cheaper it will end up being for everyone

Once the best quote has been found, I will need to know where all of you guys are at in the world so I can calculate shipping from California (where I am) to your place. After that, each of you will have to pre-pay (as a pre-order) for the pcb and shipping to me, then, and only then I will order the pcbs and ship them from me to you as soon as I receive them.
You can get an idea of my record for honesty by checking my ebay feedback (a buyer only though), my ebay ID is Kristian95. Also da9000 can vouch for me

EDIT: I'll try to keep the number of interested people updated here, but I recommend people interested in getting a pcb to pay attention to the thread at amiga.org: http://www.amiga.org/modules/newbb/v...=45531&forum=8

[Zetr0]

Looking good

still gonna need a BOM though

[Kristian95]

dang my feeble brain Zetr0, please fill me in regarding what a BOM is

[coze]

bill of materials ? (list of parts that are gonna be used)
there was a BOM at georg's website.

[Kristian95]

ah thanks coze Yup it is at Georg's homepage which I have linked to in the first post of this thread
