JJY Solder paste manufacturer — improper handling will affect the production and assembly process of Solder Paste and reduce its effectiveness during SMT manufacturing. Regarding factors such as the Solder Paste Production process, JJY gives an example to its partners.

Nowadays, for a manufacturer or small and medium-sized enterprise that produces solder paste, the key point is that to ensure product quality, attention must be paid 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 soldering. So the question arises: During the process of screening solder paste, what requirements and norms should be followed? 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 products, during the screening of solder paste, it is necessary to rely on the production process of the product. When screening for detailed principles such as PCB circuit boards and electronic components, partners will often see that solder paste particles come in 4 different types.

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 oxidize in the air, partners will choose to seal the solder paste first and then clean it further.

When screening out the solder paste that meets the individual requirements of the partners, it is necessary to consider the PCB circuit board and distinguish the post-soldering cleanliness level by a different level of Solder paste screening. There will inevitably be some problems with the no-clean process. At this time, partners need to screen out solder paste with low halogen content and no-clean solder paste without strongly corrosive compounds.

Generally, an organic solvent cleaning process 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 carbon steel plates, the preferred choice for partners is no-clean solder paste.
