Semiconductor Testing Semiconductor Testing - Semiconductor Coating Systems - Cheersonic The main goal of the test is to check whether the quality of the semiconductor chip reaches a certain standard, thereby eliminating defective products and improving the reliability of the chip. In addition, tested defective products do not enter the packaging step, helping to save cost and time. Electronic Die Sorting (EDS) is one test method for wafers. [...]
GDL Within PEMFCs GDL Within PEMFCs - Ultrasonic Spray Coater - Cheersonic Proton exchange membrane fuel cells (PEMFCs) have been spotlighted as prospective renewable energy sources because of several advantages: high efficiency, no pollution, and promptness in recharging. Currently, the major issues regarding PEMFCs are reliability and stable performance achievement at various extreme operating conditions. Since water is indispensable to the PEMFC, the freezing of water in very [...]
Semiconductor Interconnect Semiconductor Interconnect - Semiconductor Coating Systems - Cheersonic The conductivity of semiconductors lies between conductors and nonconductors (i.e. insulators), a property that allows us to fully control the flow of electricity. Components such as transistors can be built through wafer-based lithography, etching and deposition processes, but they also need to be connected to send and receive power and signals. Metals are used for circuit interconnection because [...]
GDLs of PEMFC GDLs of PEMFC - Ultrasonic Coating Systems for Fuel Cell Catalyst Coatings - Cheersonic Gas diffusion layers (GDLs), are important sub-components in PEMFC membrane electrode assemblies. The GDL, with its porous nature, plays an essential role in assisting the hydrogen oxidation and oxygen reduction reactions in the catalyst layers (anode and cathode) by allowing the reactants (hydrogen and oxygen/air) to diffuse from the flow field [...]
Medical Tubing Market Overview Medical Tubing Market Overview - Tube Coating - Cheersonic Why is the medical device market growing? Reasons for the expected growth of the medical device market include: Rapidly ageing population and increasing life expectancy More and more people are looking for a higher quality of life The incidence of chronic diseases is on the rise Rapidly increasing prevalence of infectious diseases Obesity rates on [...]
Wafer Thin Film Deposition Wafer Thin Film Deposition - Photoresist Coating - Cheersonic To create the tiny devices inside the chip, we need to continuously deposit layers of thin films and etch away the excess, as well as add materials to separate the different devices. Each transistor or memory cell is built step-by-step through the above process. By "thin film" we mean here a "film" that is less [...]
Effect of Gas Diffusion Layers of PEM Fuel Cells Effect of Gas Diffusion Layers of PEM Fuel Cells - Fuel Cell Coating - Cheersonic The efficiency and performance of proton exchange membrane fuel cells (PEMFCs) depends heavily on the heat and associated water imbalances because of their low operating temperature, which is typically less than 100℃. One of the parameters that directly affects both heat and water management [...]
Medical Tubing Materials Medical Tubing Materials - Tube Coating - Cheersonic Depending on the application, medical hoses and tubing can be produced from a variety of materials, including plastics such as fluorinated ethylene propylene (FEP), nylon, PVC, polyetheretherketone (PEEK), polytetrafluoroethylene (PTFE); thermoplastics Elastomers (TPE); and elastomers, especially silicone. Silica gel. Silicone is a key tubing material for medical devices, especially for implants. The unique properties of high-consistency silicone [...]
Wafer Etching Wafer Etching - Polyimide Coatings - Photoresist Coating - Cheersonic After the photolithography of the circuit pattern on the wafer is completed, an etching process is used to remove any excess oxide film and leave only the semiconductor circuit pattern. To do this requires the use of liquid, gas or plasma to remove selected excess. There are two main methods of etching, depending on the substance [...]
SOFCs Spray Coatings SOFCs Spray Coatings - Ultrasonic Spray Coating System - Cheersonic Fuel cell technologies have become, in recent years, an important subject of research and innovation. Among different types of fuel cells, the solid oxide fuel cells(SOFCs) have attracted significant attention due to high efficiency,fuel flexibility and silent operation. SOFCs are solid-state devices that utilize electrochemical reactions to generate electricity. Fuel is supplied to the anode [...]
