How to deal with solder paste defects in SMT assembly?

inSMTFrom a surface mount technology (SMT) processing manufacturerSMTIn the surface mount technology (SMT) process, the most crucial step is the surface mount packaging technology process. During this process, sometimes some processing defects may be encountered in the production of SMT processing, such asSolder pasteDefects. So how to deal with theseSMTWhat about processing defects in surface mount technology (SMT) processing? Now, JJY solder Paste Manufacturer will give you a brief explanation:

Generally speaking, circuit boards with solder paste defect errors can be immersed in compatible solvents, and small tin particles can be removed from the board with a soft brush. Soak and clean repeatedly instead of vigorously washing or shoveling. When problems are discovered, pass bySMTThe processed boards should be immediately immersed in the soaking solvent, as the solder paste can be easily removed before drying.

It can be wiped with a cloth to avoid solder paste and other contaminants on the surface of the circuit board. After soaking, a gentle spray cleaning usually helps remove unnecessary solder paste.

inSMTDuring the printing process of contract manufacturing and material supply, the printing cycle is rubbed between the templates in a specific pattern to ensure that the templates are on the pads rather than on the solder mask, so as to ensure that the solder paste printing process is clean.
