A3640 without caps
« on: March 06, 2012, 05:09:14 PM »
I bought a A3640 CPU-card from eBay. No guarantee was given, but "supposed working". Now that I have received the card, I noticed that the capacitors from the board have been removed, and it seems that some of the solder pads are missing too! :confused:

Is there any chance running the board without the caps? Or fix it... ?

The card is Rev 3.0.

Pads removed, you need to fix that : http://leblogdecosmos.blogspot.com/2010/07/a3640-incomplete.html


Wow, awesome repair! :cool:

C106's pad is still Ok (naturally, that's the one with most soldering space around it!), C105 and C102 have one pad missing, the last two have all pads missing.

From the pics on the linked thread, I could see some 22uF 16v caps, is this correct and are they all same?
