One can purchase solder paste from various stores online and offline. Some of those stores are SparkFun Electronics, Amazon, Ebay, DigiKey and SMT Solder Paste.
There are many places where one can purchase a solder station. One of the best places to purchase a solder station would be a hardware store like Lowes or Home Depot.

You can use a paste flux and heat (as from a soldering gun) to reattach the solder.

You can purchase Kester Solder products online at the official Kester website. You can also purchase them through companies such as New Egg and Tiger Direct.
To facilitate the soldering process, a chemical material called flux can be used to remove oxidation from the surface, keep the air from oxidizing the surfaces during soldering, and to aid in the flow of solder through the joint. Fluxes can be found within the solder (cored solder) or separately in paste form.
Flux helps promote soldering. Soldering paste might contain flux and other items to help promote soldering. The paste helps hold the flux in place while beginning to solder.
You can purchase a lead free solder on Amazon, an online marketplace that sells pretty much anything you can imagine. The price for one on Amazon is very cheap and you can get free shipping on the item as well.
You can find tomato paste in a tube for purchase at most grocery stores, specialty food stores, or online retailers.
In reflow soldering, the solder is applied as a 'solder paste' typically by using a stencil mask and a squeege. The solder paste contains both a solder flux and the solder in the form of minute solder balls. The solder paste operation is done BEFOREadding the components to the board. The board is then passed through a reflow oven at which time, the solder paste melts to complete the soldering of the components to the circuit board. The reflow oven will have several heating zones designed to preheat, activate the flux, reflow the solder, and cool the board. The oven is setup so the components receive as little thermal shock as possible, and spend only a few seconds above the solder melting temperature.In wave soldering, the components are placed on the board. THEN the board is placed in the wave soldering machine. Typically the first step in the wave solder, the bottom of the board passes through a fluxing operation which either sprays flux on the bottom or passes the bottom of the board through a flux foam. After the flux, the board will usually pass a pre-heater to activite the flux and pre-heat the board for the soldering. Then, the bottom of the board is passed through a molten solder wave (looks like a smooth waterfall only consisting of molten solder). Afterwards, there will be a stage of cool-down.Some details of the process vary by how expensive the oven or wave-solder machine is, the complexity of the circuit board involved, for what kind of volume the production line is intended for, and how 'mil or space qualified' the circuit board is.

Solder has traditionally been a tin lead alloy, but there are many variations depending on the application:jeweler's solder or silver solder, has always contained silver to prevent the solder from dissolving silver and/or gold from the item being solderedother low melting point metals are sometimes added to make low melting point solderpure tin solder is sometimes used to eliminate toxic leadetc.Solder sold in the form of wire is sometimes hollow with a core filled with flux paste to make soldering easier without the need for extensive precleaning of the work so that the solder properly wets. For plumbing purposes (where the work can be rinsed afterwords) the flux paste is acidic and very corrosive, for electronics work the flux paste is a rosin.
