Jiajin Yuanneng is a company that focuses solely on the research and development and production of tin materials. It uses high-purity primary tin materials, and its slag production rate is lower than the average level of its peers. The product has a high degree of matching, strong precision, fast soldering, firm and bright solder joints, and no phenomena such as false soldering, sharp edges or collapse. As the original manufacturer, there is no middleman price difference. We reasonably control costs and plan budgets to offer you a higher cost performance,Now, let me tell you all how to chooseSolder paste:

How to choose the right solder paste

1First, select the alloy components of the solder paste based on the assembly process, printed circuit board and components of the product(This mainly depends on the process conditions and usage requirements in industrial production as well as the performance requirements of solder paste). 

2In industrial production, according to the product(Printed circuit board)Choose the solder paste that suits you based on the requirements for cleanliness and the different degrees of cleanliness after soldering. When adopting the no-cleaning process in production, it is necessary to select no-cleaning solder paste with low halogen content and no strong corrosive compounds. When using the solvent cleaning process, solvent-cleaning solder paste should be selected. When using the water cleaning process, water-soluble solder paste should be selected.BGA,CSPGenerally, high-quality no-clean silver-containing solder paste should be selected.

3According toPCBThe activity of solder paste should be selected based on the storage time of the components and the degree of surface oxidation.

4According toPCBThe assembly density(Is there a fine spacing?)During the production process, the appropriate particle size of the alloy powder should be selected. Generally, the particle sizes of commonly used solder paste alloy powders are divided into four particle size grades, and fine spacing is usually chosen20-45um.
