In order to ensure the quality of the welded products during welding, choose a suitable one for your own productSolder pasteIt's quite important. How should one make a choice? Is there any basis? Shenzhen JJYSolder paste manufacturerFocus12Based on the research and development of the soldering industry in recent years, here are some reasonable suggestions for our partners:

    According to printingpcbThe cleanliness of the circuit board, the surface oxidation degree of electronic componentspcbSelect solder paste based on its relative density.

    Solder pasteThe types include: no-cleaning solder paste, organic solvent-cleaning solder paste, and water-soluble solder paste . The no-cleaning workflow uses halogen-containing and non-corrosive no-cleaning solder paste. In the organic solvent cleaning process, organic solvent cleaning type solder paste is adopted. In the water cleaning workflow, water-soluble solder paste is adopted.

    The specificity of solder paste is selected based on the oxidation degree of circuit boards and electronic components. Aerospace products are available for selectionRHierarchical. The circuit board is relatively long during storage and its surface is prone to oxidation, so it is selectedRAIt is layered and requires cleaning treatment after welding.

    The particle size of the alloy powder should be selected based on the assembly relative density of the circuit board. Particle size classification4There are different levels. The finer ones are generally selected to be between 20 and 45 nanometers.
