Cyberstorm PPC - 060 socket

[MRamos]

Hi guys,

please, someone could provide me,
which is the socket for 060 from www.digikey.com
(or another site) that fits on Cyberstorm PPC ??

I'm looking for a 060's socket replacement, because
I'm getting very strange errors on my A4000 and
my suspect is this socket.  :roll:

thanks
Mauricio

PS: sorry my english

My understanding is that the 68060 socket is NOT a through hole design on the CS PPC/Mk III. Meaning that even if you were to locate a replacement socket it would be almost impossible for anyone without special equipment to replace it.

Perhaps send the whole board out to the company in France before even touching it?  No doubt other people will respond with more information.

Good Luck...

The original socket is a BGA (ball grid array) style device, so very difficult to fit the same kind of socket.

I've repaired a number of the 68060 sockets on the Cyberstorm mk3 boards by removing the existing socket using SMD hot air rework tools and "making" a new socket out of single pin sockets.
A little time consuming and you need very good soldering skills to be able to do it correctly.  But it works well and any solder joint problems are obvious.

Hi,
thanks guys for replies ...

I will try to send an email to this french guy,
and if I could not pay (Euros is veeery expensive),
I'll try the Castellen's solution... God help me

Am sooooo glad I read this - I'd nearly bought an 040 CSPPC in the past with the intention of upgrading it to 060.
I'd have been rather pi55ed to find BGA work required.

Goddam phase 5!! Why not just use 060 sockets in the first place for the extra few pence?
  Good hardware for the most part, I suppose its a small grumble - but to use BGA 040 sockets on their last model?!?!  One would have expected them to learn from the upgrade requirements of the blizzard 040/060 and CS 040/060 and not limit their hardware to being more-or-less non-upgradeable.

@Boot_WB:

They are upgradeable, but as the socket is surface-mount and a very large component, its solders are very sensitive to mechanical stress of the card and thus easily break.

@MRamos:

you don't need a new socket for your 060. The existing one will be perfectly good.

There are various solutions to improve stability (BUT MUST BE DONE BY A *VERY* EXPERIENCED TECHNICIAN WITH PROPER EQUIPMENT).

The first one is using a soldering iron with not much power and give heat to each one of the pins of your socket (yes, in the side were you insert the 060). If your socket is not in a very bad state it may be enough to keep your CSPPC stable again.

The cleanest and ultimate method is removing the entire socket, cleaning all the contacts, cleaning the board and re-solder the 060 socket with high quality "tin" (I'm not sure about the translation of the spanish word "estaño") and with a proper soldering station.

A friend of mine repaired my CSPCC, and he resoldered the entire socket and the UWSCSI chip too. And all that without using "flux"! :-) he has told me that its much easier if you use "flux", so your friend technician will have an easier task. BTW my CSPPC now works much better than when it was new :-) He told me that it is even faster than is phase5 CSPPC. Mine it's a DCE one... it seems they did a pretty bad job soldering the components of the CSPPC.

But remember, the technician must be very experienced with SMD components, a CSPPC is an expensive toy.

Hi Crumb,

Thank you for your reply, I'm very happy to read that!!!

In next weekend I'll be meeting some amiga users at Amilive (Brazilian Amiga User's Meeting) and maybe one member will bring a soldering station that blows hot air (dont know how is the translation for it) to make this job ...

I hope this fix my CSPPC problems

best regards
