- Q: The solder paste has dried up. Can you add a little soldering flux?
- It's better not to add. It adds a lot to the reliability of the welding
- Q: Where is the difference between the flux of welding machine and the flux of wave soldering?
- Requirements for dip welder flux depends on whether there is a flux spray preheating function, automatic spraying machine with preheating function, and soldering flux dip welding requirements can be consistent, if there is no preheating function, then dip welder on soldering flux and moisture flux activity requirements will be relatively high, of course, automatic dip welder can open the preheating function well, it will affect the efficiency, hope I can help you to reply!
- Q: What occasions are they used? What do we usually use when welding with iron iron?
- Solder paste: used for patch welding of circuit boards. Solder paste is a paste of a mixture of tin, silver, alloy particles and soldering flux.Soldering flux: a kind of auxiliary welding material. The main component is rosin. A surface oxide used to clean the metal of a welded part.These two substances are nothing at all!
- Q: What are the commonly used fluxes?
- The most used is rosinThe flux function: rosin resin and surfactant flux in the production of chemical reaction at a certain temperature, can remove the welding metal surface oxidation film, and rosin purpose and can protect the surface of metal shed no longer oxidation at high temperatures. Flux can reduce the surface tension of molten solder, and it is beneficial to wetting and diffusion of solder
- Q: Is flux harmful to people's health?
- No, that's just general combustion support
- Q: Can aluminum solder be used without soldering flux?
- May not。 Aluminum and tin are not fused. Welding aluminium material with aluminium welding wire
- 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: 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!
- The reasons are as follows:1, first of all, separate PCBA to analyze, will be completely tested with flux plates, do not weld the case;2, if in the absence of welding, or these circumstances, that is, the presence of flux resistance is smaller. That can be done by replacing the soldering flux or preheating the third segments of the wave soldering to 150-180 degrees to see if it can be heated to bake the halogen from the soldering flux itself;3, another case is the tin wire itself, because the tin line itself also exists to help welding flux, some manufacturers have put a halogen, it will inevitably produce leakage, itself is a halogen active agent, excessive use of conductive. The international allowed only 5 parts per thousand.4, because you are SMT patch, solder paste is also a key factor to check, to see if it will not conductive, such as you can test the resistance before the wave soldering, it is recommended to use well-known solder paste manufacturers. Such as thousand live, AF and so on. If the solder paste itself has leakage phenomenon, it must first improve from the source.Through the above points, you should be able to find the problem, I hope you will soon resolve the incident.
- Q: What is a soldering flux? What does the solvent include?
- There are borax, hydrochloric acid and so on
- Q: Is there any corrosion in the soldering flux? How do you use it to solder?
- Due to the strict restriction of solid content and corrosive flux, the welding performance is necessarily limited. In order to obtain good welding quality, new requirements for welding equipment must be put forward with inert gas protection function. In addition to the above measures, the cleaning process also requires more stringent control of the welding process parameters, including welding temperature, welding time, PCB, tin depth and PCB transmission angle. Different cleaning parameters of wave soldering equipment should be adjusted according to different cleaning fluxes, so as to achieve satisfactory cleaning effect.
