JJYSolder paste manufacturerIt will have an impact on the production and packaging process of solder pasteSMTDuring the production and manufacturing of quality, it leads to a reduction in its efficacy; For factors such as the production process of solder paste, JJY gives an example to its partners.

    Nowadays, for a manufacturer or small and medium-sized enterprise that produces solder paste, the key lies in the fact that to ensure the quality of the product itself, it is necessary to pay attention to the norms and specific requirements in the production process. This is also the difficulty that determines whether the quality of solder paste is good in electric soldering. So the question arises: During the process of screening solder paste, what requirements and norms should be followed for the screening? What is the basis and principle? Next, let the staff of JJY Solder Paste Factory lead the partners to understand the production process together:

    In order to produce qualified process products, during the screening of solder paste, it is necessary to rely on the production process of the product.pcbWhen screening some detailed principles such as circuit boards and electronic components, partners will also often see solder paste particles4A different model.

    In most cases, partners will select those with a tiny spacing ranging from 20 to 45 micrometers. They can refer to the assembly density of the printed circuit board to further screen the particle size of the solder paste, or the length of time the printed circuit board has been placed as a basis. Since the solder paste will be oxidized in the air, partners will choose to solder the solder paste tightly first and then further clean it.

    When screening out the solder paste that meets the individual requirements of the partners, it is necessary to considerpcbThe circuit board and the post-soldering level can be distinguished by a different level of cleanlinessSolder pasteFilter. There will inevitably be some problems with the no-clean process. At this time, partners need to screen out bulbs with low halogen content and no-clean solder paste without strong corrosive compounds.

    Generally, the cleaning process with organic solvents is required.When water-soluble solder paste is selected in the process flow after water cleaning,It enables us to screen out cleaning solder pastes with organic solvents. For cast carbon steel plates, the preferred choice for partners is the no-cleaning solder paste. For those who want to know more about solder paste, flux paste and solder paste, and are also troubled by the problem of not knowing how to select solder paste in daily life, please come to consult Shenzhen JJY Industrial Technology Co., Ltd. and learn and grow together!
