- Q:Remove the flux residue on the heating platform
- The heating flux on the platform under high temperature continuously, almost residue carbonization and oxidation flux, flux contact platform will become black or black and yellow, it is unable to use clean ordinary method. The first to use chemical solvents (ethanol or toluene, acetone and so on) the flux residue clean, the oxide layer on top of the platform color is deep, wiping several times with dilute hydrochloric acid 5%-10%, can a new clean, then rinse clean. Attention must be put on protective gloves and protective glasses, so as to avoid accidents.
- Q:Hello I was doing the main board, recently encountered a problem: is always negative capacitance is high, then do a test, is a drop in capacitor flux, after soldering out capacitor on the bad, but did not drop the flux too out right. Excuse me, what's the reason for this? Thank you
- Are you sure the capacitor is broken? I don't have much experience in this area. But if the flux is too high or the pad is oxidized high and the melting time is insufficient, the problem will be obvious
- Q:The manual is 63/37 260 welding tin furnace temperature after other joints are not only full of gun patch due to the cost of tin is used disposable flux please analyze the reasons in detail a bit if there is a better solution
- The reason is that the PCB pad is oxidized, while the removal of the oxide film BG in the soldering flux results in poor tin plating.Flux: flux, solder paste and also, there are two kinds of liquid, in metallurgy is clean in a chemically welded metal surface for soldering, brazing or welding material, positioning. The use of different metal welding flux is also different, for example: the use of ammonium chloride or rosin soldering; welding galvanized iron and other zinc surface material with hydrochloric acid or zinc chloride; copper brazing or welding to black metal with borax. The welding material is easy to adhere to the corresponding welding metal surface after melting at high temperature, but the metal surface is easy to form oxide layer at high temperature, so that the welding material is difficult to adhere to the surface. The flux is stable at room temperature and has a strong reducibility at high temperatures. It can remove the oxide layer on the metal surface. In addition, the solder in soldering and brazing process can also play the role of wetting agent.
- Q:Ratio of submerged arc welding wire and welding flux
- The ratio of welding wire to flux should be 1:1.2--1.4. If it is the construction site water tank ring submerged arc welding, in the range of 1:1.6.
- Q:How do you distinguish flux from alcohol?It tastes about the same. What's the easiest way to distinguish between them in reality?
- Some flux solvent can be used alcohol as solvent, but for lead-free solder, the welding temperature is 200-250 degrees, the boiling point of alcohol is too low, only as part of the mixed solvent, less amount. Because soldering flux must not be allowed to burn under welding temperature, you can distinguish it from this
- Q:How does solder paste blanch after soldering?!
- There is a problem with the solder paste, and you need to consult the manufacturer of solder paste.
- 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:It's no use washing the nozzle with alcohol, so it's clean as well.
- 1. nozzle wear --- replace nozzles or accessories.2. nozzle clogging ---- cleaning and maintenance.
- Q:Can H10Mn2 wire and sj102 flux be matched in submerged arc welding? Is there such a match in the tower flange welding of a wind turbine?
- Fluorine alkali type sintered flux sj102 flux can be used with H10Mn2 welding wire for submerged arc welding, which is equivalent to F5A4-H10Mn2. Weldable low alloy structural steel, high strength hull structural steel, steel for pressure vessel. Can be used for multi pass welding, double-sided welding, welding and single wire narrow gap submerged arc welding.Sj102 flux has excellent welding performance, stable arc combustion, groove slag removal, excellent performance, good weld bead forming, basically no increase in Si and Mn, which belongs to the metallurgy of neutral, low temperature impact toughness is high, suitable for DC welding, welding wire and cathode.
- 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.
