inSMTDuring the entire production and manufacturing process, solder paste packaging and printing are correctSMTThe quality of production and manufacturing has relatively significant hazards. There are many factors that endanger the quality of solder paste packaging printed products.JJYSolder paste manufacturerLet's take an example:

    For instance, the production, manufacturing and processing technology of steel mesh, the perforation design plan of steel mesh,PCBThe flatness, the setting of main parameters for packaging and printing, and the characteristics of the solder paste itself, etc.

    How to choose what is available to oneselfSolder pasteAnd? What are the factors influencing the assessment? I believe that all the partners have always had doubts.

In fact, there are many factors that need to be evaluated to determine whether solder paste meets the standards . For instance, the composition of tin alloys, the composition and properties of fluxes, and the strength of spot soldering pressure, etc.

    Solder paste can be classified into several types according to the specifications and dimensions of metal material particles. Therefore, when it comes to which model and specification of solder paste to use and how to choose the right solder paste for oneself in specific production, partners must follow a key criterion. That is to say, at least five tin balls can be placed in the position with fewer holes or welding layers on the steel mesh. The diameter of this tin ball is based on the larger specification of that model.

    The quality of electric soldering directly determines whether a solder paste is usable. Based on the quality of electric soldering after convection, statistical analysis was conducted on the data information. The defects and problems caused were analyzed, and it was determined whether they were related to the quality of the solder paste. Problems such as poor wetting or short circuit caused by the solder paste are very likely to occur.

    On the production site, some simple verification experiments can be carried out. By conducting production verification on different brands and types of solder pastes, a solder paste that suits the production characteristics of one's own product can be selected from among them.
