Where can someone purchase solder paste?
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.
What has the author Colin C Johnson written?
Colin C. Johnson has written: 'Solder paste technology' -- subject(s): Solder pastes
Your car heater on back has come unstuck how do you fix it so it will clear again the solder has come off?
You can use a paste flux and heat (as from a soldering gun) to reattach the solder.
To open a mobile repair shop what are the tools required?
solder wire, solder paste, BGA paste, magnifying lamp, SMD Rework station, circuit board cleaner, soldering station, all size star screw sets, and DC power supply tool
What is the purpose of core in hollow solder wire?
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.
Why do moist paste is use in dry cell?
it is just because the ions can easily travell in the liquid paste. so the electrolysis can easily be processed.
What does solder consist of?
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.
What is the difference between flux and soldering paste?
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.
What is the difference between reflow soldering and wave soldering regarding lead free alloys recommended by NEMI?
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.
How do you braise a copper pipe joint?
Clean the two pieces of pipe with emery paper or a pipe cleaning wire brush. put a little solder paste on male pipe and insert in connector. Heat the connection for several inches in both direction to warm up the pipe then concentrate the torch a quarter inch below and around the joint on the female end and the braising rod. Touch the rod to the joint. When the temperature of the pipe is hot enough the rod will melt and flow or be sucked sucked towards the heat. Move the rod all around the joint. LOL Actually, while most of the above information is true, I wouldn't recommend using solder paste or any type of flux when you braise refrigerant lines. You don't want anything besides R-22 (freon) or R 410-A (puron) in the lines and solder paste could mess up the compressor. Your should only use solder paste or flux when soldering!
How do you remove solder flux stains from clothing?
To remove solder flux stains from clothing, wipe off any excess of flux from the clothing with a piece of paper towel. Mix 1 tbsp. of baking soda with enough warm water to make a paste. Apply the baking soda paste to the flux using an old toothbrush. The baking soda will act as a neutralizing agent. Wipe away the baking soda and the dissolved flux from the clothing with a damp cloth, then let it air dry thoroughly.
When text is copied is it removed from its current location?
No it is just copying and pasting it will still be where u found it when you remove it.
