I think a more sustainable model is by delivering a "kit" ie pcb + parts. This should also allow for lower prices, even if Xenepp took a small profit. That will allow people to concentrate on soldering. Some repair shops will do soldering work for pay aswell.

The problem is that the only way it would allow for lower prices is if parts are bought in larger quantities (25+) which would require a fairly large initial cash outlay for the person putting together the kit.

If anyone has an extra few thousand dollars lying around and wants to do so, they could probably make a few bucks profit, but I don't know if it's worth the effort for anyone, especially since I don't know how much demand there would be for a kit. Most people seem to want a pre-assembled one.

Well but HOW do you solder it. Because you won't be getting the soldering iron between the chip and the pcb.


You can use an oven to do BGA-soldering at home, here's one starting point:

(there's a lot more of those, I have one pdf which tells you how to make an oven controlled by a MCU to get the spot-on temperature changes).

Check Mouser.com, Maplin.co.uk ..?
Try google aswell. Sometimes it works.
Which country or continent do you live in?


I live in Norway, Europe.   And, I didn't find the 68000-CPU  on mouser either.  The PIC-MCU I don't have any problems finding :-)

The problem with soldering of bga is that you can't verify the soldering operation before applying power.
Unless you (ab)use an old radio tube with an HV supply as a x-ray source. And use ccd? as a image receiver (the principal way it's done in a professional enviroment).

So soldering is complicated, but verification is the hard stuff (unless blowing chips is acceptable).

Could we use something like this to solve the BGA problem?

Sure, but it's extremely expensive and therefore I don't see this going into the minimig project.

Well, there's good news and bad..

First the good.. the Minimig PCBs have arrived! They look great (see here)

The bad news, it looks like I'll not have the time to do a run of complete PCBs.  :cry:

I've just gone back to college and it's more work that I ever imagined. That plus life equals no time for much of anything. The free time I do get I just want to sleep!

I can always get the bare PCBs though and have 9 here with folk's names on them so if you want them just drop me a PM, but a big sorry to all those waiting for complete boards, it just isn't going to happen from me.  :cry:

Anyway, I'm going to start emailing those who pre-ordered the bare boards and collecting payments and getting them shipped out.

@Xenepp

Yes, lack of time, I know what that means :S

But I think we must all thank you for all your effort, although personnally I wanted only a populated PCB :(

@CD32Freak,

Pretty cool, did you only have the one board made?  Did you make the v1.1 changes that Dennis suggested?

I love the Galaxy Quest quote on the board, it fits the Amiga spirit so well. :-D

Joel, did you only have 10 bare boards manufactured?  Am I one of the lucky nine?

Three questions then...

1)  Have you been able to assemble your own MiniMig to make sure the boards work?  (I hope you will have enough time to assemble at least one board for your own use.)

2)  Did you already get the components for the boards you were planning?

3)  If you did, can you sell the parts and board to us so that we basically have a kit?

Thats really cool that you've got some of the boards and I would still be interested in a blank board from you either in this or another batch should you do one :) Well done getting them done this far!
