Jason: I have used preforms from both Alpha and Indium. You specify the flux that you want added. Both companies have a number of standard shapes and sizes available. Both will custom make shapes for you as well. If you're willing to do without flux, you can get samples faster. The flux is usually added on demand. Shelf life is about a year. Minimize handling to avoid oxidation of the preforms. Be prepared to order large quantities. One small container can hold 5,000-25,000 preforms.
