Product Details

Cell production process, the effect of screen printing will directly affect the conversion efficiency of the battery, the printing core is the aspect ratio of the silver paste after printing. Therefore, the screen, silver paste and squeegee must be kept innovative, when the preparation of higher requirements of screen printing

SPS-AS-SL-Carbon Squeegee For Sola3

Development of photovoltaic squeegee:Just ten years, the gate line requirements more and more fine, has been from the initial 60um into the current 18um; followed by the squeegee replacement (as shown below), now SPS-AS-SL is more and more popular!

1.SPS-AS-SL's core strengths are:

1.1 Electrostatic Dissipation Benefits

During the printing process, squeegee, screen, ink,silicon wafer friction static electricity is easily generated and static electricity accumulates to a certain voltage difference.Can cause silver particles, small particles, flying ink, etc.

1.2 Advantages of cutting type squeegee

The blade is smoother, and the ink on the screen is cleanerSharper edges for finer lines

1.3 After testing, the support plate squeegee saves 8% of the silver paste compared to the traditional squeegee!The traditional squeegee printing process is easily deformed, the stable printing pressure and the printing angle cannot be maintained, and silver wire breaks easily.The operator must increase the printing pressure and reduce the printing angle to reduce the breakage, which will increase the ink consumption.

1.4 High print times

The surface roughness of the bottom of the squeegee is low and the surface area is small, reducing the area of the contact solvent ,solvent corrosion squeegee speed is reduced.Squeegee is not easy expansion and wear.Japan's latest polyurethane formula, more solvent-resistant, more wear-resistant.

1.5 Unilateral design

Less solvent etched area

Smaller deformation area

Maintain stable printing pressure and angle for a long time

Company Profile

Plet company is located in Changzhou, China, which is very close to Shanghai. He once sold screen printing inks and served in many electronic industries. He has extensive screen printing experience and realized the importance of squeegee in the screen printing process. In 2013, Plet began to engage in the research and production of support plate squeegee, and established the SPS brand squeegee, which provides stable printing angle and printing pressure for many precision screen printing customers in China.

Customer Praise

A. Photovoltaic Company Production Manager India:We are a company that prints battery sheet, SPS-AS carbon fiber squeegee printing Battery sheet grid is relatively small, printing life is long, each average reaches 50,000 times.

B. PCB circuit board company Technical staff China: Before we cooperate with SPS Squeegee, when we do the through hole printing process, the silver paste is not easy to penetrate the hole, and the scrap rate is very high. After talking with SPS technology, they recommended the new squeegee, which helped us solve the problem of low yield rate of through-hole printing. Thank you very much.

C. Membrane switch company quality management personnel Vietnam: SPS recommended R angle scraper printing transparent color effect is excellent, no squeegee marks, the surface looks very smooth, we will also apply R angle squeegee  to the window printing liquid printing process, hope to reduce the rate of defective rate.

 D. Technical Director of Chip Manufacturing Company Taiwan: We print insulating ink on special film, and 160 products are printed on A4 size film. This has high consistency on film thickness. The film thickness made by traditional squeegee,the film thickness in the middle and the film thickness of the edge product differ by 3 microns, and the carbon fiber squeegee using SPS solves this problem, and the film thickness of the entire printing surface is controlled by 13±1 μm.
