- Q: Prior to using the silver brazing flux, but do not know how to use this, the finished product is unstable, easy to disconnect. I was welded by spot welding machine. The temperature was about 1000 degrees. I also used solder paste, but the surface of the finished product was oil. What kind of soldering flux can be used to guarantee the success rate of welding?.
- Ultrasonic welding machine, without soldering flux, find it yourself
- Q: TAMURA flux and solder paste is what is different?
- I have never heard of this brand. But popular speaking, soldering flux is cheap. Solder paste is very expensive. Joke. Two kinds of products is the same process, but is not the same as the direction of. The flux for tin tin dipping, or wave soldering. But suitable for spot welding, solder paste, or in the process of infrared BGA. A totally different aspect
- Q: TitleWhat is the difference between rosin flux solder paste?What is the difference between rosin, soldering flux and solder paste? What are their respective functions? Thank you
- The flux is known, rosin, solder paste to use flux, the most critical is to increase the welding and welding solder objects (poor infiltration effect infiltration, solder is not well attached to the welded object, appeared a round ball, it is easy to weld), other auxiliary heat removal, such as oxidation conduction, reduce surface tension, so that the metal solder joint appearance etc.. Flux is divided into three categories: one is inorganic flux, two is organic flux, and three is rosin. Inorganic flux is generally a certain acid or salt, such as phosphate H3PO4, organic flux is mainly some organic acid or organic halogen; relatively speaking, the most active inorganic flux, remove the oxide film had the best effect, but also has strong corrosion resistance, it is easy to hurt the metal and solder joints, generally can not be used in the welding of electronic products. Solder paste is emulsified with oil after the inorganic flux, welding can be cleaned by solvent, but some parts of the circuit board is difficult to clean, so generally do not recommend the use of solder paste. Organic flux is second only to inorganic flux, and also has certain corrosiveness, and the residue is not easy to be cleaned, and the volatile matter is harmful to human body. Is the main component of rosin rosin acid and Levopimaric acid, generally neutral, liquid has a certain activity, showed weak acidity, can react with the metal oxide surface, formation of abietic acid copper compounds, and suspended in the surface of the solder, and the use of no corrosion, insulation resistance. Rosin is, in general, the best soldering flux.
- Q: What is soldering flux? Is alcohol the main component of soldering flux?
- Welding aid is a reducing agent which reduces metal oxides to metals and is easy to weld.
- Q: What occasions are they used? What do we usually use when welding with iron iron?
- Solder PCB board will use solder paste. On other occasions, usually not
- Q: How does solder paste blanch after soldering?!
- Because the flux in the solder paste melts at high temperature and volatilize. When the solder paste reaches a certain temperature, the solder paste will melt and become liquid, and the flux will break down and diffuse on the surface and periphery of the tin bath. When the temperature drops, the tin liquid solidifies into tin, and the flux does not decompose and volatilize, and remains. The residue is usually yellow or white.
- Q: How to use aluminum welding flux?
- Aluminum welding flux in the electrode and electrode welding together on the line.Cleaning method of 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: Rosin is an insulator. Why is rosin used as a soldering flux in industry? Doesn't that lead to electricity in the wire? When the teacher taught me, he always coated the wires with a layer of rosin, coated with a tin of solder, and soldered the wires to the circuit board with solder. In this way, the rosin on the head does not conduct electricity, will it not affect the circuit?
- Rosin, also known as pine gum and resin, its formula is C20H30O2, is a weak organic acid, its acid value is about 160. It is non corrosive, non hygroscopic, and has good insulation, more important is it has five basic functions: 1 flux? Can remove oil, sweat, dust and other resistance welding; 2? To prevent welding when heated oxidation; 3? Can enhance the liquidity of solder; 4? After the completion of welding, can protect the cleaning of uniform cooling; 5 easy to clean?.The active component of rosin is mainly rosin acid, which accounts for about 80% to 90% of the total rosin content. At normal temperature, rosin is solid and its activity is almost no action. The melting point of rosin is between 172 and 173 degrees centigrade. When heated to the melting rosin rosin temperature, and then it can play a role of the soldering flux. When the temperature reaches or exceeds 300 degrees, it begins to decompose and carbonization. After cooling, it can be solidified again and lose its activity again. After welding, the residue is evenly distributed, non corrosive, and has good stability and insulation.In the mass production of printed circuit boards, the boards are easy to be contaminated and are usually cleaned thoroughly. 1, three, 1, 1 are usually used as cleaning agents, three dichloroethane, trichloroethylene, and three chlorine.In the amateur conditions, generally can not be cleaned, such as obvious pollution, alcohol can be cleaned, the area can be used cotton swab dipped in alcohol several times; when the area is large, you can use a brush dipped in alcohol scrub. Note that the alcohol should be clean every time.
- Q: I would like to manually wire lead end immersion tin, do not know what kind of flux selected, and the proportion of the flux does not know, check for a long time did not find, please heroes help ah?
- The flux is matched with a chemical liquid. Taking the question, I'm telling you the secret recipe
- Q: What is sintered flux?
- Sintered flux is a kind of high quality, high efficiency, energy saving and environmental friendly flux. The welding flux is smokeless, tasteless, arc free and without spatter when welding. The manufacturing process has no environmental pollution, low energy consumption, the use of raw materials. The preparation of scientific spirit full of sintered flux, welding process, strong adaptability, can be used for welding of thin plate, angle weld and super standard, high speed, multi wire, anti blowhole, narrow gap, deep groove under various working conditions, good slag detachability, weld good forming. Most of the sintered flux products are spherical and granular, which facilitates the delivery and recycling of solder flux in the welding process.
