In the process of cell production, the effect of screen printing will directly affect the conversion efficiency of the cell, the core of printing is the aspect ratio of the silver paste after printing. Therefore, the screen, silver paste and squeegee must remain innovative, when writing higher screen printing requirements in just ten years, the requirements of the gate line is becoming more and more fine, has been from the initial 60um into the current 30um, or even finer; Subsequent to the replacement of the squeegee (as shown in the figure below), and now SPS-AS-SL single-sided photovoltaic carbon fibre squeegee is becoming more and more popular!
The development of PV squeegee: in just ten years, the gate line requirement has been getting finer and finer, has been from the initial 60um into the current 18um; followed by the replacement of squeegee (as shown in the figure below), now SPS-AS-SL is getting more and more popular!
Core Benefits of SPS-AS-SL
| Static-dissipative | During the printing process, static electricity is easily generated due to friction between the squeegee, screen, ink, and silicon wafer. When static electricity accumulates to a certain voltage difference, silver particles, small particles, and ink particles can be generated. |  |
| Cutting Edge | Smooth edge, cleaner ink squeegee on the screen, sharper edge, suitable for finer grid lines |  |
| Compared with the traditional squeegee, the support plate squeegee saves 8 per cent of silver paste! The traditional squeegee printing process is easy to deform, the printing pressure is not stable, the printing angle can not be maintained, and it is easy to produce the broken fence phenomenon. The printing pressure must be increased and the printing angle must be reduced, which will increase the consumption of ink. |  |
|
| High print resistance (Single side lifespan exceeding 60000 times) | Adopting Japan's recent polyurethane formula to reduce the abrasive force between squeegee and screen, the life of screen and squeegee is improved at the same time. Squeegee adopts cutting process, low surface roughness and small surface area at the bottom of squeegee, which reduces the area in contact with solvent and the speed of solvent corrosion of squeegee, and squeegee is not easy to swell and wear. |
 |
| Single-sided design | Reduced area corroded by solvents; The deformation area is small and lasts for a long time; Maintain stable printing pressure and angle. |  |

SPS-AS carbon fiber squeegee for duplex drum screen printing machine
SPS-AS carbon fiber squeegee is suitable for reciprocating cylinder screen printing machine. It uses carbon fiber board and Japanese ASM anti-static solvent-resistant polyurethane rubber. The printing quality is stable and the service life is high.
GM-IO is a UV curable screen printing insulating ink with excellent adhesion, high flexibility, good printability and UV curing fast drying characteristics, suitable for blood glucose meters, keyboard circuits, membrane switches and so on.
In the process of screen printing, squeegee, screen plate, substrate material and other mutual friction, generating static electricity. When static electricity accumulates to a higher voltage difference, the edge of the pattern will produce flying ink, drawing and other bad.SPS-ASM anti-static squeegee resistance <108Ω, part of the charge through the squeegee dissipation, reduce the voltage difference, to avoid flying ink and wire drawing and other problems.

FGB-MP Glass Fibre Board Squeegee
SPS-MP-X series squeegee is a new generation of one-piece squeegee specially developed by Plet and Japan Polyurethane Chemical Company for the narrow line width printing of battery cells. Compared with the traditional sanding squeegee, it has significant effect on wet weight control, printing life and efficiency improvement, etc. Using this squeegee can achieve the purpose of cost reduction and efficiency improvement.
1. Manufactured using Japanese squeegee processing, it exhibits superior solvent and wear resistance; 2. The fiberglass board scraping glue combines the fiberglass board with scraping glue, offering the elasticity of the scraping glue and the structural support of the fiberglass board. This allows for a stable printing angle to be maintained even during extended periods, ensuring uniform ink thickness.
