2 Key Products
Release Film Product Line
MLCC Release Film
GTW’s highly uniform release films feature excellent coating adhesion and stable release performance. By applying a silicone-based formulation and antistatic agents to one or both sides of a PET substrate, GTW ensures outstanding peel strength and consistent performance across various applications. These films serve as functional layers to protect adhesive surfaces in electronic and display components, as well as providing mechanical protection during the MLCC manufacturing process.
Applications:
Primarily used in the production of ceramic capacitors and RF components. Features include excellent peel stability, strong release layer adhesion, and a high residual adhesion rate.
Product Features:
Low migration characteristics, eliminating the risk of silicone residue transferring to the adhered surface
Uniform coating, suitable for a wide range of casting thicknesses
Excellent flatness, ensuring uniform MLCC thickness, easy release, and neat stacking
Good temperature resistance and low thermal shrinkage
Produced in Class 1,000 cleanrooms with localized Class 100 controls
Comprehensive model range, offering roughness levels from high and medium to low and ultra-low (12–20 nm)
BOPET Base Film for MLCCs
BOPET base films for MLCCs (Multi-Layer Ceramic Capacitors) feature high mechanical strength, rigidity, and toughness, along with excellent electrical insulation properties. They are transparent, highly glossy, non-toxic, odorless, and tasteless, while also offering resistance to abrasion, folding, pinholes, and tearing. As MLCCs move toward higher capacitance and miniaturization, the demand for an increased number of stacked ceramic layers necessitates thinner film sheets. Consequently, achieving superior flatness and smoothness in the BOPET release films used in MLCC manufacturing presents a primary challenge.
Applications:
Primarily used in MLCC manufacturing processes, the electronics industry, and various electrical appliances.
Product Features:
Stable Roughness: Surface roughness ranging from 10 to 40 nm meets the requirements for various ceramic sheet applications.
High Cleanliness: Produced in Class 1,000 cleanrooms to ensure the product's visual quality meets optical-grade standards.
Excellent Flatness: Formed via a single-step, three-layer co-extrusion casting process, ensuring consistent thickness and stable downstream processing.
Good Temperature Resistance: Stable thermal shrinkage in both machine and transverse directions ensures thermal stability across various processing temperatures.
Consistent Quality: Manufactured using world-class process control technology to ensure reliable product quality.
PET Base Film for MLCCs
This PET base film for MLCCs offers excellent mechanical strength, temperature resistance, and surface flatness. Corona treatment enhances surface wetting tension, ensuring the uniform application of release agents. Manufactured in a Class 1,000 cleanroom environment with surface roughness controlled between 10 and 40 nm, the film meets the rigorous demands of high-capacitance, miniaturized MLCCs regarding ultra-thin ceramic sheets.
Product Features:
Low migration: Eliminates the risk of silicone residue transferring to the adhered surface.
Uniform coating: Precise control of coating weight with minimal tolerances to suit various applications.
Excellent flatness: Ensures uniform MLCC thickness, easy release, and neat stacking.
High temperature resistance: Low thermal expansion and contraction during the MLCC manufacturing process, ensuring the flatness of ceramic layers and precise stacking alignment.
Filtration Solutions
Applications for Ceramic Capacitors
Ceramic capacitors are critical components in microelectronic devices. During manufacturing, filtration is essential to remove harmful particles that could otherwise compromise performance. GTW’s filtration solutions effectively remove large particulate impurities during the ceramic capacitor production process.
Ultrapure Water Applications:
Removing contaminants from source water helps ensure the quality of the finished product. Harmful contaminants can lead to poor product performance and reduced reliability. GTW’s filtration solutions for ceramic capacitor applications are designed to facilitate the manufacture of durable, high-performance components.
Conductive Paste Applications:
The use of conductive pastes requires filtration to ensure the uniformity of conductive metal particles; the process allows particles of the target size to pass through the filter element while screening out larger ones. GTW provides filtration solutions for conductive pastes that help enhance the performance of the final components.
Wastewater Treatment Applications:
Almost all manufacturing processes generate wastewater, which must be filtered before discharge to remove or neutralize chemicals and metals. GTW offers filtration solutions that facilitate wastewater treatment, helping to protect the environment and meet increasingly stringent discharge regulations.
