Made from Japanese scratch glue, it has excellent solvent and wear resistance. The inclined edge of the blade is ground, and the smaller printing angle is more suitable for squeezing conductive ink into the hole, resulting in stable conductivity of the printed product. Fiberglass board design is more convenient to install and provides long-term stable support.

Printed circuit board to conductive layer classification, can be divided into single-sided, double-sided, multilayer three categories. Double-sided and multi-layer principle has a common point, that is, both need to be connected to its level of conductor. The common aspect of adding conductors between layers lies in the punching or drilling of holes at designated points on the printed circuit board, and then forming a conductor layer around the walls of the holes. This conductor layer then creates electrical contacts between the layers to form a circuit. There are many ways to form a mutual hole connection, such as: leads, rivets, or no plating method (chemical precipitation of copper, blackening method) will be the conductor material plated on the wall of the hole, and then direct plating method and so on. This type of method has its own advantages and disadvantages, but also very effective, but the manufacturing cost is expensive and bring the complexity of environmental protection. The generation of through-hole technology, the formation of effective interconnecting holes, can make up for this shortcoming.
Mesh through-hole printed circuit boards are a new approach to the design of double-sided vias for metallised printed circuit boards. The process is to be able to conductive silver paste, carbon paste or copper paste and other printed materials through the screen leakage printing penetration into the pre-fabricated holes, Fill the aperture with conductive material of injection or rivet structure, and solidify it to form interconnected conductive holes.
Glass fibre board squeegee instructions
| Traditional squeegee is made of polyurethane rubber, long time printing, squeegee absorbs solvents in the ink, hardness decreases, swelling and deformation, printing angle is unstable, not suitable for precision screen printing. Glass fibre plate squeegee adopts the combination of glass fibre plate and squeegee, which has the elasticity of squeegee and the support line of glass fibre plate, and it can maintain a stable printing angle for a long time, and the thickness of printing ink is even. |  |

Packaging, Storage
Packaging
Paper packing：10Pcs/Box
Storage
①Store indoors at 40°C or lower. Do not store in places with high temperature and humidity, direct sunlight and UV rays. (Recommended storage conditions: 23°C±2°C, 60% or lower humidity).
②Do not store near heat generating equipment or dusty places.
③Prohibit bending and heavy pressure, stack flat and stack no more than 20PCS.
④After being left for a long time at low temperature, the squeegee adhesive should not be used immediately after being moved to room temperature, but should be left at 23° for more than 3 hours before use.
Grinding
Please clean the ink on the surface of the squeegee after use and put it on the SPS-DR squeegee rack for 12 hours to wait for the solvent to be released.
②The M type conventional squeegee needs to be clamped in the squeegee holder for grinding; the FGB/AS squeegee with support plate can be removed for grinding.
③Manual grinder for grinding
Maximum grinding with 250mesh grinding wheel in one pass Rough grinding 0.5mm/Fine grinding 0.2mm
Maximum grinding with 400mesh grinding wheel 0.2mm rough grinding/0.1mm fine grinding
④ Ground squeegee can be combined with the use of SPS-Sander to polish the edge of the cutter, the cutter is smoother.
Attention:
SPS squeegee are available for multiple grinding, grinding without melting, fine grinding surface and smooth cutter.
SPS-SG squeegee Grinder can be supplied with various customised type grinding wheels: U type C angle R angle (K1-K5).

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.
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!
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.
