Product Overview
Our Electronic Potting for Avalanche Photodetectors is a professionalSilicone Potting Compound developed for the encapsulation, sealing, insulation and protection of avalanche photodetectors. As a leading manufacturer of electronic Potting Compound and silicone raw materials, we optimize the formula for the high sensitivity, insulation, anti-interference and light transmittance requirements of APDs. Unlike ordinary potting silicones, it maintains ultra-high light transmittance after curing, does not block weak light reception, 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 APDs and ensuring long-term stable operation for procurement partners.
Key Features & Advantages
- Ultra-High Light Transmittance & Sensitivity Preservation: Ultra-high light transmittance after curing, ensuring unobstructed reception of weak light signals by avalanche photodetectors, without affecting photoelectric conversion efficiency and detection sensitivity; no interference to APD signals, maintaining signal integrity and detection accuracy, which is critical for APD performance.
- 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 avalanche multiplication effect of APDs.
- Excellent Temperature & Environmental Adaptability: Operating stably from -60℃ to 220℃, with outstanding high and low temperature resistance; can absorb internal stress caused by temperature cycles, protecting APD chips and welding wires from damage; good ozone resistance, chemical erosion resistance and waterproof moisture-proof performance, adapting to harsh indoor and outdoor working environments of optical detection equipment.
- Strong Adhesion & Easy Operation: Excellent adhesion to aluminum, copper, stainless steel and other metals, as well as PC, PMMA and PCB materials (common in APDs), 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 APDs.
- 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 light transmittance, which is crucial for APD sensitivity.
- 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, light transmittance and sealing performance of avalanche photodetectors.
- 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 avalanche photodetector packaging molds or casings.
- Curing: Place the encapsulated APD 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.
