| New question Anyone familar with KB3926QF Seems there is a code after the part number. ie A1, C0, D2 Do these codes matter? I tried replacing a Code C0 with a code A1 and had issues. Anyone have a datasheet on this controller chip? Used on a lot of motherboards. |

Nevertheless it matters cuz they're different chips. I tried before they're not interchangeable (just for ene) Winbonds 773ldg and 775ldg are interchangeable(773 may not be ldg; but I know 773 and 775 are interchangeable for winbond). Good luck... | |

| I never had an issue with expired solder. Some of my solder balls are 3+ years old and they work fine. I do keep them in a sealed container. I think the flux is more important not to be too old. Metal stays metal, as long as it doesn't oxidize, but the chemicals in flux change over time. |
