Product Overview
This premium Electronic Encapsulation Adhesive includes addition curing and condensation curing types, serving as high-quality industrial Silicone raw materials for SMT electronic packaging. It is widely used for encapsulation, sealing, filling and pressure resistance of surface mount noise filters. It boasts excellent adhesion and thermal stability for PCB, PC, PMMA, CPU and multiple metal substrates including aluminum and copper. After curing, the flexible colloid absorbs thermal cycling stress, protects tiny filter chips and bonding gold wires, and integrates waterproof, moisture-proof, dustproof and anti-corrosion functions to ensure long-term stable operation of miniature noise filter components.
Technical Specifications
This Silicone Encapsulant features a wide operating temperature range of -60℃ to 220℃, with ultra-low volatile content and high structural strength. It supports customizable viscosity, hardness and operating time, adapting to high-precision SMT mounting and potting processes. With excellent ozone and chemical erosion resistance, it maintains stable physical and dielectric properties in long-term high-frequency working environments, fully meeting industrial surface mount component packaging standards. Product Features & Advantages
Optimized exclusively for miniature surface mount noise filters, it solves common SMT component defects such as noise drift and structural damage:
1. Full environmental protection: Offers outstanding waterproof, moisture-proof, dustproof and shockproof performance, effectively resisting ozone and chemical corrosion.
2. Extreme temperature stability: Tolerates -60℃ to 220℃ continuous operation, relieves internal thermal stress and prevents filter noise suppression failure caused by temperature cycling.
3. Superior bonding performance: Firmly adheres to various metals and non-metal substrates, no peeling or gaps on compact SMT structures.
4. Stable filtering performance: Low volatility and consistent insulation avoid signal interference, maintaining precise and stable noise filtering efficiency.
Application Scenarios
Specially designed for encapsulation and protection of surface mount noise filters, miniature SMT filter modules, high-frequency noise reduction components and precision circuit filter units. Widely applied in consumer electronics, communication devices and industrial control systems. It effectively stabilizes product noise reduction accuracy, reduces component failure and rework rates, improves finished product yield, and lowers manufacturers’ production and maintenance costs.
Step-by-Step Usage Process
1. Pre-stirring: Fully stir component A to evenly mix settled fillers and thoroughly shake component B for uniform texture.
2. Proportional mixing: Strictly follow standard AB component weight ratio to ensure stable curing and protective performance.
3. Vacuum defoaming: Place mixed glue in a 0.01MPa vacuum container for 3-minute defoaming to eliminate tiny bubbles affecting precision packaging.
4. Curing treatment: Supports room temperature or heating curing. Initial curing allows subsequent processing, with full curing completed within 24 hours, affected by ambient temperature and humidity.
Certifications & Compliance
The product complies with ISO9001, CE, UL and ROHS international standards, meeting global precision electronic industry specifications and supporting cross-border export and industrial-grade SMT component packaging.
Customization Options
Customized services are available. Product hardness, viscosity and operating time can be adjusted to match diverse packaging processes of surface mount noise filters.
Production & Quality Control
We adopt standardized production and full-process strict QC. Pre-production sample testing and pre-shipment full inspection guarantee stable batch performance and consistent product quality.
FAQ
Q1: Will this potting silicone affect SMT noise filter performance? A: No. It features ultra-stable dielectric and insulation properties, causing no signal interference and preserving original noise filtering accuracy.
Q2: Can stratified silicone be used normally? A: Slight stratification after long storage is normal. Even stirring before use will not affect encapsulation and protection performance.
Q3: What is the correct storage and usage method? A: Store in sealed and dry conditions. Mixed AB silicone should be used up at one time to avoid performance degradation and waste.
