Q:What solvents do you use to clean rosin and flux? Can you make it yourself? It used to be the water, but now it's home. There's no water in the house

Methanol can clean rosin, can also be used to confect flux, but the ability of methanol cleaning rosin is not strong, but the price is still the best trichloroethylene, far, methanol is 3.3 yuan /KG; trichloroethylene is 13 yuan /Kg; there are three kinds of commonly used solvent flux: methanol, ethanol, isopropyl alcohol, three alcohol prices are 3.3. 8.7, 13.

Q:Can I use soldering iron without soldering flux?

Flux can be without soldering flux, but it must be assured of your quality!

Q:What is the brazing flux

When the flux of low melting point, called soldering, such as soldering; when the flux of high melting point, called brazing, such as brazingSoldering flux is usually a mixture of rosin as the main component. It is an auxiliary material to ensure the smooth progress of welding process. Welding is the main process in electronics assembly process, flux is used in welding materials, the main role is to remove the solder and flux of materials to be welded on the surface of the oxide, the metal surface to achieve the necessary cleanliness. It again to prevent surface oxidation during welding, reduce the surface tension of welding material, improve the welding performance of flux. The quality directly affects the quality of the electronic products.

Q:What is the name of welding material, welding flux, welding rod, welding wire belt. The relationship between them. Answer more details. Thank you

YD alloy gas welding rod etc. all kinds of welding materials. Nickel base powder recycled foundry tungsten carbide powder gas tungsten carbide rod casting cast iron electrode various rare electrode copper and copper alloy rod heat resistant steel electrode of stainless steel electrode for high manganese steel electrode stack cobalt base electrode 1-12, valve rod mould electrodes may impact wear-resistant electrode high temperature wear-resistant electrode silver electrode wire and solder welding ring cobalt cobalt base electrode welding wire the electrode of tungsten carbide wear-resistant electrode machining electrode wear

Q:How to use aluminum welding flux?

With aluminum flux soldering, it is necessary to have very good experience and operating method, which is difficult for ordinary welders. There is a need for soldering flux, more suitable for novice welding operation, mainly used for welding of thin aluminum, or dissimilar aluminum welding, and two kinds of aluminum, it is best to use low temperature aluminum WE53 can search on the Internet, "WE53 Weiouding welding of low temperature aluminum welding operation video details operation video

Q:Is carbon dioxide gas shielded welding wire a flux cored wire?What is the explanation of solid cored wire?.

Flux cored wire is used as flux cored wireSolid welding wire, as the name suggests, is no core, that is, wire drawn into welding wire, the surface will do some anti rust treatment, and sometimes copper plating, but certainly not anticorrosive paint. Paint is harmful to welding, it will produce pores

Q:In welding, do you want to re engineer the welding process if the change of the flux grade, such as SJ101, becomes SJ301?

No need to do it againWhen the Fe-1 type steel is submerged in multi-layer welding, the welding type should be re evaluated for changing the type of welding flux. These two are neutral flux, do not need

Q:In the product after SMT, the performance test is no problem, but to the customer after two or three months or more, that one of the key chip resistor 0603 package resistance becomes smaller and smaller from 24K to about 21K, I put all the lines around this resistance are disconnected, found resistance or 21K, then I the resistance from the board removed, the resistance is not bad, or 24K, use high-powered magnifying glass, the intermediate SMD package with flux residue and more, is not because of the flux and the residues have internal resistance, request the master answer!

Look at your soldering flux type and content. Should the alcohol base be better?

Q:When welding, the mold has the crystallization, is not easy to clear, whether has the crystallization flux?

If the parts are cast welding as long as preheating can obtain good welding effect, the disadvantage is if there is a coating, the coating is easy to change, so you want to control a suitable temperature, we have been doing. Different fluxes have been tried, but in view of the ease of introducing impurities into the battery, they are not used at all.

Q:What are the commonly used fluxes?

Flux is divided into smelting flux and non smelting flux. Non smelting flux is divided into bonded flux and sintered flux. Our country is mainly smelting flux, and the most used in smelting flux is HJ431.
