Regarding the lead-free solder paste printing of solder paste manufacturers, some partners may have some doubts, such as: "What is the printing process like?" JJYSolder paste manufacturerLet's learn about it together with our friends:
Lead-free flux pasteOne of the more serious problems is that during the entire reflow soldering process, its wettability cannot reach the same level as that of tin-lead solder paste.
If the punching size of the template is reduced, there will be a situation where lead-free solder paste cannot cover itpcbSolder pad. Different lead-free solder pastes have different wettability. If nitrogen is used in the reflow soldering process, then the lead-free solder paste willpcbThe moisture condition on the pad will change.
inSrinivasa AravamudhanIn scientific research5],When the solder paste printing is offsetpcbWhen using the circuit board pads, observe whether this process can be well moistened during reflow soldering and also cover the pads. What is applied are the tin-lead solder paste and lead-free solder paste sold by popular solder paste dealers.
In this scientific research, the circuit board of a test sample was tested, and the surface was electroplated with nickel and gold(ENIG)The solution, however, involves the application of different components and packages for the test samples.
