Product Overview
Our Electronic Potting Compound is specially developed for Voltage Reference Sources, dedicated to encapsulating, sealing, insulating and protecting voltage reference chips, precision resistors, and their solder joints. As a leading manufacturer of liquid silicone and addition curing silicone, we optimize the formula for the high stability and low drift requirements of voltage reference sources, enhancing anti-interference, low curing stress and excellent adhesion. Compared with epoxy potting resin, it has minimal volatile content, no exotherm during curing, good flexibility, avoiding voltage drift and ensuring stable reference voltage output.
Key Features & Advantages
- Ultra-Low Voltage Drift & High Stability: Customizable low-dielectric-loss formula, effectively reducing electromagnetic interference (EMI) and temperature-induced voltage drift, ensuring long-term stable reference voltage output, critical for high-precision electronic systems.
- Low Curing Stress & No Component Damage: Cures without exotherm, minimal shrinkage rate, ultra-low curing stress, protecting fragile voltage reference chips and precision resistors from mechanical damage, ensuring consistent performance of the reference source.
- Strong Adhesion & Wide Compatibility: Excellent adhesion to PCB, PC, aluminum, copper, stainless steel and reference source substrates, tightly bonding voltage reference sources and substrates; no corrosion to sensitive electronic components, ensuring firm and long-lasting encapsulation without peeling.
- Excellent Temperature & Environmental Stability: Stable performance from -60℃ to 220℃, resisting extreme temperature changes and harsh environments; waterproof, moisture-proof, dust-proof and anti-corrosive, adapting to industrial, automotive and consumer electronics working conditions.
- Easy Operation & Customizability: Adjustable weight mixing ratio, optional vacuum degassing (0.01MPa for 3 minutes), curable at room or heated temperatures, improving encapsulation efficiency; as a professional Silicone Potting Compound manufacturer, we customize viscosity, hardness and dielectric properties to match different voltage reference source specifications.
How to Use
- Pre-Mix Preparation: Thoroughly stir Component A to evenly distribute settled fillers, and shake Component B vigorously to ensure uniformity, avoiding stratification that affects adhesion and voltage reference stability.
- Precision Mixing: Strictly follow the recommended weight ratio of Component A to B, stirring slowly and evenly to ensure full integration without air bubbles that cause insulation gaps or electrical interference.
- Degassing (Optional): After mixing, place the adhesive in a vacuum container at 0.01MPa for 3 minutes to eliminate air bubbles, then carefully pour it onto voltage reference sources to ensure full coverage of chips and solder joints.
- Curing: Place the encapsulated voltage reference sources at room temperature or heat to accelerate curing; enter the next process after basic curing, and ensure 24 hours of full curing. Note: Environment temperature and humidity significantly affect curing speed and reference voltage stability.
