Wash the water after washing, very sticky after washing, alcohol after washing pan white
General enterprises use washing board water, or with water-based cleaning agent cleaning, and now I have a flux (non water soluble), after welding water can be washed directly residual, the address is not issued, useful to the contact me
After washing the plate is very sticky, there may be less washing water, cleaning is not enough. Or the dissolution is not enough. The flux residue not only rosin, some organic active agents, most of them are white solid, soluble alcohol is not strong, and also contain a certain amount of water, with alcohol to clean the board, most of the time will certainly be white board. Specific or consult the manufacturer of solder that uses now, they should have the ability and method to solve this kind of problem.
After welding, usually with DT-78A or DT-68A to clean, these two cleaning agents in the electronic plate cleaning is generally relatively clean, and manual cleaning, pay attention to the direction of the product.The flux is in the process of welding to welding and insulation effect of the welding flux in the later, and no clean flux is not only to help, and after welding surface clean, no special requirements without flux plate washing.Advantages of no cleaning flux:1., good weldability, solder joints are full, no welding beads, bridges and other undesirable2. non-toxic, no pollution to the environment, safe operation3. after welding, the board surface is dry, non corrosive and non stick4. after welding, on-line testing ability5. match the material of SMD and PCB board6. after welding there is a specified surface insulation resistance value (SIR)7. adapt to welding process (dip, spray coating, foam, etc.
