Need someone to fabricate this for me

Hi,

Forgive me if this is the wrong place but i am struggling and out of options at this point.

I designed a PCB for an ATMega8 and its basically a low profile Arduino that solders to PCB's similar to how ESP8266 modules attach using castellated holes

The issue is i am a complete novice when it comes to using a hot air rework station so i am struggling to solder them and if i do, i can never seem to program them via Arduino as ISP

I was wondering if there is anyone in the UK that could fabricate and send me these completed PCB's for a project for the original xbox.

I think my design works but again i have no way of testing them.

The image on the left is the final thing with it attached and the PCB on the right is what it looks like assembled (i think i have all the components i need on that board for it to be sufficient but again (complete novice at this)

If anyone would be able to help, i can happily supply the Gerber/schematic for what i have named (ATMegaX)

Thanks

They are ceramic Resonators yeah, And as for programming i'm using Arduino as ISP as you should be able to do that with these. i have done it successfully before using a DIP package ATTiny and a QFN version of the ATTiny but this doesnt want to play nicely.

Can you post a picture of your programming set up and explain exactly what happens when you try.

I dont currently have everything setup but basically involves an Arduino Uno with 6 Dupont cables coming from the uno to the test points on the module, Using avrdudess to attempt to read the fuses results in signature 000000. I also made test boards with every pin exposed on the ATMega but also gives the same result. Maybe the resonator stops it from working?

But at this point i am out of ideas

If you are in the UK you could send me a little board and I'll see if I can get it going.

I'd need to solder little wires to the castellations and I'd hang a scope on the SPI bus to see what it's doing.

I've got an Arduino and I've got various Atmel AVR aids (although it's quite a while since I did anything AVR based).

I can send you them no problem, Would you like a completed board and a chip and blank PCB with resonator too?

That way if you can get it working, you probably have a better chance of soldering it and getting them working.

I can send you the 0403 resistors and caps too if you would like?

May as well send everything, my postal address is in my E14 profile - I think any one can access it but if not please let me know.

I may be the exception to the hot-air rule then because that is all I use without major complications (that includes those tiny QFN chips with thermal pads) . I think hot-air works well for small PCBs like this one.

Hello Alex,
Got the board - post office did their best to wreck it - looks like they used a rolling pin !

I have pliers - I can fix it !
