Product Overview
Our Electronic Potting for Gunn Diodes is a professional Silicone Potting Compound developed for the encapsulation, sealing, insulation and heat dissipation protection of Gunn diodes. As a leading manufacturer of electronic Potting Compound and silicone raw materials, we optimize the formula for the high-frequency stability, insulation, thermal conductivity and anti-interference requirements of Gunn diodes. Unlike ordinary potting silicones, it features low dielectric loss, does not interfere with high-frequency signal transmission, absorbs internal stress from temperature cycles, resists corrosion and ozone, and has excellent adhesion to aluminum, copper, stainless steel and PC/PMMA/PCB, effectively protecting Gunn diode chips and ensuring long-term stable operation for procurement partners.
Key Features & Advantages
- Superior Insulation & Anti-Interference: Ultra-strong insulation performance (dielectric strength ≥25 kV/mm, volume resistivity ≥1.0×10¹⁶ Ω·cm), preventing short circuits and ensuring safe operation; effectively isolating external electromagnetic interference and voltage interference, avoiding signal distortion and ensuring stable working status of Gunn diodes.
- Excellent Thermal Conductivity & Temperature Adaptability: Operating stably from -60℃ to 220℃, with outstanding high and low temperature resistance; good thermal conductivity promotes heat dissipation of Gunn diodes during high-frequency operation, avoids overheating damage; absorbs internal stress caused by temperature cycles, protecting Gunn diode chips and welding wires from damage.
- Strong Adhesion & Easy Operation: Excellent adhesion to aluminum, copper, stainless steel and other metals, as well as PC, PMMA and PCB materials (common in Gunn diode modules), forming a tight seal without detachment; two-component design, easy to mix evenly, optional vacuum defoaming (0.01MPa for 3 minutes), supports room temperature or heated curing, full curing in 24 hours, suitable for batch production of Gunn diodes.
- Environmental Protection & High Stability: Addition-curing silicone, non-toxic and non-hazardous, fully compliant with EU RoHS directive; low volatility, high strength, no stratification after long-term storage (stir before use without affecting performance); mixed glue can be used up at one time, avoiding waste and reducing procurement costs.
How to Use (Step-by-Step Guide)
- Pre-Mixing Preparation: Fully stir Component A in its container to mix the settled filler evenly, and shake Component B thoroughly to ensure uniform consistency, avoiding affecting curing effect, adhesion and dielectric performance, which is crucial for Gunn diode high-frequency stability.
- Mixing: Mix Component A and Component B according to the specified weight ratio (customizable), stir slowly and evenly to avoid generating air bubbles, which may affect insulation, thermal conductivity and sealing performance of Gunn diodes.
- Degassing (Optional): Put the mixed potting compound into a vacuum container, degas at 0.01MPa for 3 minutes to completely eliminate air bubbles, then pour it into Gunn diode packaging molds or casings.
- Curing: Place the encapsulated Gunn diode at room temperature for curing or heat to accelerate curing; enter the next process after basic curing, and full curing takes 24 hours. Note: Environment temperature and humidity significantly affect curing speed and final performance.
