Nicolas,

i am looking into production & issues surrounding that for all boards , that are stable , and classix once the few items remaining are sorted . in most cases automated testing is mostly by default , to check the pcb's and parts for non functioning bad ic's etc , which can be changed before dispatch to the client , and is now done to satisfy regulations etc as any pcb made for or in europe has to comply now to RHOS and other weird money making regulations CE etc

the main problem to get the price down , is to have volume , but you need to weigh the costs of lower output being automation and hand soldered i.e labour , the main problem being to set up a pcb automated build system can take 2 -3 hours setup time , even though then it can produce a pcb in about 20 - 30 seconds

they don't like setting up for only a hour production run , as it then costs about the same time as 4 hours
all lost revenue for them , so it's a trade off in small numbers .

anyhow will let you all know once i have the figures worked out , see what Ethan can find out too

i have access to companys in China and Singapore if they are willing to do them , lets see , it's all in the numbers

Dave

I also think fully assembled boards would be required. I am interested in
classix and tiny but don't have the required equipment to produce them...

For the tests, it would be great... but I'm afraid this would significantly
raise the price of boards. I guess we could develop a test program that
would test all the onboard components... I don't see the advantage of have
tests run by assembling company.

Hi Ethan

I think fully populated and tested boards would be the best - The arm
boards ( classix and tiny) use fine pitch part ( 0.5mm ) which are very
difficult to solder without proper equipment ( at least hot air).

What do others think ?

Regards

Antoine

Hi Antoine,

Are you looking just at PCB's or fully populated and programmed boards?
I'd be happy to produce and market the PCB's, and I think I can probably
find a way to get them assembled (at least with the components that are
impossible to do manually), although I'd still need to do some reasearch
to
make an estimate for that.

Regards,
Ethan

Betreff: [Paparazzi-devel] Commercial boards

Hello world

We are trying to find a way to get ready made boards commercially
available.
Gumstix said they would do it but seems very slow to do so.
If you know a company that would provide this service please let us know.
In the same time we have setup a page on the wiki to collect buying
intentions and get an estimate of the needed volume.

Please edit this page :

Best regards

Antoine
