Re: Soltek SL-KT600-RL

Well four months later I finally got round to fixing this board (we used a spare laptop in between). The 3300uF capacitors were tough to remove, tough to clean out the holes, and tough to re-solder, all due to the large planes on one of the pins. I finally resorted to preheating that area of the board with a hair drier and using a Hakko 936 at its highest temperature setting. I also used a solder sucker which seemed to work without any board damage. Probably due to poor technique I could not get the desolder braid to work successfully at pulling the solder...

Re: Soltek SL-KT600-RL

With matching Rubycon low ESR capacitors from Badcaps.net. I sent the request in today:

3300uF, 6.3v, MBZ, 10mm x 25mm
1500uF, 16v, MBZ, 10mm x 20mm
1000uF, 6.3v, MBZ, 8mm x 11mm

I used to be a R&D hardware electronics engineer in a previous job so I feel reasonably comfortable with a soldering iron. Unless there is something else wrong this with the board this should be a successful and inexpensive fix compared to new motherboard, memory, OS, etc.

This info is reference material for others to find. This 2002 (7 year old) Soltek SL-KT600-RL motherboard started becoming unstable with random and increasingly frequency MS-Windows bugchecks. Decoding the bugchecks seemed to imply L2 cache errors. Further searching lead to the bad capacitor issue which visual inspection confirmed.

The Soltek SL-KT600-RL motherboard has:
* Qty 6 KZG (Chemicon?) 3300uF 6.3V 10mm caps
* Qty 3 KGZ (Chemicon?) 1500uF 16V 10mm caps
* Qty 9 OST 1000uF 6.3V 8mm caps

The six 3300uF caps are located under the heatsink...
