2. Extreme temperature stability: Tolerates -60℃ to 220℃ continuous operation, relieves internal thermal stress and avoids frequency offset caused by temperature fluctuations.
3. High adhesion & low volatility: Firmly bonds various substrates with minimal volatile content, no contamination or interference on precision circuit structures.
4. Stable tunable performance: Consistent insulation and dielectric properties ensure accurate, repeatable frequency tuning without signal attenuation.
Application Scenarios
Specially applied for encapsulation of tunable filter circuits, adjustable frequency RF filter modules, precision signal tuning units and wireless communication adjustable filter components. Widely used in communication base stations and precision RF test equipment. It stabilizes tuning accuracy, reduces circuit failure and debugging rates, improves product yield, and lowers manufacturers’ production and after-sales costs.
Step-by-Step Usage Process
1. Pre-stirring: Fully stir component A to evenly disperse settled fillers and shake component B thoroughly 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.
