Product Overview
This professional Electronic Encapsulation Adhesive includes addition curing and condensation curing types, serving as high-quality industrial Silicone raw materials for RF electronic packaging. It is widely used for encapsulation, sealing and filling of electronic components, featuring excellent adhesion and thermal stability for PCB, CPU, PC and PMMA substrates, as well as aluminum, copper and stainless steel metals. After curing, the liquid silicone forms a tough protective layer that absorbs thermal cycling stress, protects internal chips and gold bonding wires, and offers integrated waterproof, insulation, dustproof and anti-corrosion protection for interdigital bandpass filters.
Product Features & Advantages
Optimized for high-frequency interdigital bandpass filters, this Silicone Encapsulant outperforms ordinary potting products in signal stability and environmental durability: 1. Multi-protection performance: Features excellent waterproof, moisture-proof, dustproof, shockproof and anti-corrosion properties, with strong resistance to ozone and chemical erosion.
2. Ultra-wide temperature resistance: Stably operates at -60℃ to 220℃, relieves internal stress caused by high and low temperature cycling to avoid filter performance failure.
3. Low volatility & high adhesion: Low volatile content, high structural strength and superior bonding force for various non-metal and metal substrates.
4. Stable RF performance: Uniform cured structure avoids dielectric fluctuation, ensuring consistent bandpass filtering accuracy without signal attenuation or offset.
Application Scenarios
Specially applied for encapsulation and protection of interdigital bandpass filters, high-frequency RF filter modules and wireless communication filter components. It is widely adopted in communication equipment and precision electronic instruments. This Potting Compound stabilizes filter signal transmission accuracy, reduces product failure and rework rates, improves finished product stability, and helps manufacturers cut production and after-sales costs effectively.
Step-by-Step Usage Process
1. Pre-stirring: Fully stir component A to evenly disperse settled fillers and shake component B thoroughly to ensure uniform texture.
2. Proportional mixing: Strictly follow the standard AB component weight ratio to guarantee stable curing and performance.
3. Vacuum defoaming: Stir the mixed glue evenly and place it in a 0.01MPa vacuum container for 3 minutes of defoaming before pouring.
4. Curing process: Support room temperature or heating curing. It reaches initial curing for subsequent processing, with full curing completed within 24 hours, affected by ambient temperature and humidity.
Certifications & Compliance
All products comply with ISO9001, CE, UL and ROHS international standards, meeting global precision electronic industry specifications and supporting cross-border export and industrial-grade commercial applications.
Customization Options
Customized services are available. Product viscosity, hardness and operating time can be adjusted according to customers’ unique packaging process requirements for interdigital bandpass filters.
Production & Quality Control
We implement standardized production and full-process strict quality inspection. Pre-production sample testing and pre-shipment full inspection ensure stable batch performance and consistent product quality.
FAQ
Q1: Will this potting silicone affect filter bandpass accuracy? A: No. It features ultra-stable dielectric properties, which will not cause frequency drift or signal interference to interdigital bandpass filters.
Q2: Is stratified silicone usable after long storage? A: Colloidal stratification is normal. Even stirring before use will not affect its protective and encapsulation performance.
Q3: What is the correct storage method? A: Store in sealed and dry conditions. Mixed AB glue should be used up at one time to avoid waste and performance degradation.
