Product Overview
Our Electronic Potting Compound is specially developed for Multi-Chip Modules (MCMs), dedicated to encapsulating, sealing, insulating and protecting high-density integrated MCMs, chip stacks, interconnections and delicate bonding points. As a leading manufacturer of liquid silicone and addition curing silicone, we optimize the formula for MCM’s dense integration, enhancing fine gap penetration, low signal interference and thermal stability. Compared with epoxy potting resin, it has minimal volatile content, no exotherm during curing, low shrinkage, and good flexibility, avoiding damage to fragile interconnections and ensuring stable MCM operation.
Key Features & Advantages
- Low Viscosity & Dense Gap Penetration: Customizable low viscosity formula, excellent fluidity, easily filling tiny gaps between multiple chips, bonding points and interconnections in MCMs, ensuring full encapsulation without dead corners, critical for high-density integration protection.
- Excellent Thermal Stability & Stress Absorption: Stable performance from -60℃ to 220℃, effectively dissipating heat generated by multiple chips; absorbs thermal stress caused by high-temperature cycles, protecting chips, welding gold wires and interconnections from damage, extending MCM service life.
- Strong Adhesion & Wide Compatibility: Excellent adhesion to PC, PCB, aluminum, copper and stainless steel, tightly bonding multiple chips, substrates and interconnections; no corrosion or damage to delicate components, ensuring firm and long-lasting encapsulation without peeling.
- Low Interference & High Insulation: High dielectric strength (≥25 kV/mm) and volume resistivity (≥1.0×10¹⁶ Ω·cm), isolating adjacent chips and interconnections, avoiding signal crosstalk and electromagnetic interference, ensuring stable MCM performance.
- 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 curing speed to match different MCM sizes and integration densities.
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 gap penetration and adhesion to MCM chips and interconnections.
- 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 short circuits or signal interference between chips.
- 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 MCMs to ensure full infiltration of tiny gaps between chips.
- Curing: Place the encapsulated MCMs 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 bonding performance.
