The Iwill KA266-R is a PC motherboard from 2001 for AMD socket A CPUs and has hardware IDE RAID with 3 DDR 266/200 slots, 4 IDE channels, 5 PCI slots, 4.1 channel integrated sound (C3DX HSP56), and an AGP slot.
Known Issues
Bulging capacitors around PCI slots
Aluminum electrolytics around the PCI slots are starting to bulge from age and all electrolytics on this board are the same brand and will probably do the same.
Causes
- Age
- Cap Chemistry
- Heat around PCI card area & CPU
Solutions
- Replace all electrolytic caps
Disassembly Notes
- Handle PCB by edges to avoid stressing BGA devices or touching static sensitive devices
- Use ESD safe equipment
- This PCB is a high density multi-layer PCB with a high thermal mass, some soldering irons may struggle
