How to avoid screen blockage and wire breakage during the printing process of platinum paste printing?

In the field of printing,Research Platinum Brand YB8207 Printing Platinum SlurryLaunched by Advanced Institute (Shenzhen) Technology Co., Ltd., due to its wide application in the fields of electronic components and circuit board manufacturing, it is crucial to avoid network blockage and wire breakage during the printing process.

1、 Network blockage problem and avoidance methods

（1） Analysis of the reasons for network blockage

1. In terms of slurry characteristics
   • YB8207 printing platinum paste from Yanbo brand has a certain viscosity, and if there are significant changes in environmental temperature and humidity, it may affect its viscosity characteristics. For example, in environments with lower temperatures and higher humidity, the slurry may become more viscous, which increases the risk of clogging. According to the general characteristics of printing materials, changes in temperature and humidity can alter the physical properties of the material, such as viscosity.
   • Although the platinum powder particles in the slurry are small and evenly dispersed, if they are not stirred evenly before storage or use, it may lead to excessive concentration of local particles, which can easily clog the screen during the printing process.
2. Printing equipment and processes
   • Improper selection of mesh size for the wire mesh may also lead to blockage. For the YB8207 printing platinum paste of the research platinum brand, if the mesh size used is too high, such as exceeding 300 mesh (it is recommended to use 300 mesh nylon or stainless steel mesh for this paste), the mesh size of the mesh is too small, and the particles in the paste are easily trapped, causing blockage of the mesh.
   • If the processing steps after printing are not carried out according to the correct process, such as not cleaning the screen in a timely manner after printing, the residual slurry will dry up in the mesh and block the mesh.

1. Slurry treatment
   • in useResearch Platinum Brand YB8207 Printing Platinum SlurryBefore, ensure that the slurry is thoroughly stirred. The stirring speed and time should be adjusted according to the actual situation to ensure that the platinum powder particles are evenly dispersed in the slurry. Generally, low-speed stirring can be used for 5-10 minutes to avoid generating too many bubbles that may affect the printing quality.
   • Strictly control the temperature and humidity of the printing environment. It is recommended to control the temperature of the printing environment between 20-25 ° C and the humidity between 40% -60%. This can maintain the viscosity of the slurry relatively stable and reduce the possibility of clogging.
2. Equipment and process adjustments
   • According to the recommended process, choose a suitable mesh of wire mesh, such as 300 mesh nylon or stainless steel wire mesh. And the integrity of the wire mesh should be checked regularly. If any damage or deformation is found, it should be replaced in a timely manner.
   • Improve the cleaning process after printing. After each printing, the screen should be cleaned with a specialized cleaning solvent. The cleaning solvent should be compatible with the YB8207 printing platinum paste of Yanbo brand to avoid chemical reactions that may damage the screen. Spray cleaning or immersion cleaning can be used to ensure that the residual slurry in the mesh is completely removed.

2、 Disconnecting problem and avoidance methods

（1） Analysis of the cause of wire breakage

1. In terms of slurry supply
   • If there is a problem with the supply system of YB8207 printing platinum slurry, such as blockage of the slurry conveying pipeline or abnormal operation of the slurry pump, it will cause discontinuous slurry supply and lead to wire breakage.
   • The liquid level of the slurry in the container is too low, which may also lead to insufficient suction and cause wire breakage.
2. In terms of printing operations
   • Improper setting of pressure, angle, and speed of the ink scraper is a common cause of wire breakage. If the pressure of the ink scraper is too high, it may excessively squeeze the wire mesh, causing the slurry to be cut and resulting in wire breakage; If the angle of the ink scraper is not appropriate, it cannot evenly scrape the slurry through the wire mesh, and it will also cause wire breakage; The speed of the ink scraper is too fast, and the slurry cannot fill the mesh in time, which can also cause wire breakage.
   • The uneven tension of the wire mesh is also an important factor. If the tension in a certain part of the wire mesh is too high or too low, the deformation of the wire mesh will be inconsistent when the scraper moves, which can easily cause the slurry to break.

1. Slurry supply guarantee
   • Regularly inspect and maintain the slurry supply system. For slurry conveying pipelines, regular cleaning should be carried out to prevent impurities from blocking the pipelines; For slurry pumps, maintenance should be carried out according to the equipment's maintenance requirements to ensure their normal operation.
   • During the printing process, it is important to constantly monitor the liquid level in the slurry container. When the liquid level is too low, it is necessary to replenish the slurry in a timely manner to ensure a continuous supply of slurry.
2. Printing operation optimization
   • Reasonably adjust the pressure, angle, and speed of the ink scraper. regardingResearch Platinum Brand YB8207 Printing Platinum SlurryDetermine the appropriate scraper pressure through experiments, generally between 0.1-0.3 MPa; The angle of the ink scraper can be adjusted between 45 ° and 60 °; The speed of the ink scraper is optimized within the range of 10-30cm/s according to the printed pattern and accuracy requirements.
   • When installing the wire mesh, professional equipment and methods should be used to ensure uniform tension of the wire mesh. A tension meter can be used to measure the tension of the wire mesh, and the tension error is generally required to be within ± 5N/m.

Through in-depth analysis of the clogging and breakage problems of YB8207 printing platinum paste during the printing process, and taking corresponding avoidance measures, the printing quality and efficiency can be effectively improved, and the advantages of this printing platinum paste in the fields of electronic components and circuit board manufacturing can be better utilized.
