9. Apply the solder using either preforms or cuttings from a roll; use the amount that will cover the area to be tinned. 10. Preform steps #5, 6, and 7. 11. For a proper solder joint, the capacitor must be tinned with the same solder that is used on the land. This can be accomplished either by solder dipping or by reflow using a soldering iron.

A broke off a GPU capacitor, what should I do?
If it is a capacitor and not just a really weirdly placed resistor, it''s a multi-layer ceramic capacitor (MLCC), so the way to tell what kind of capacitors you need is to find the package size of it. Basically get out some calipers, measure the cap you''ve got, and reverse engineer what the capacitor package is.
