Product Overview
Our Electronic Potting for PIN Diodes is a professional Silicone Potting Compound developed for the encapsulation, sealing, insulation and protection of PIN diodes. As a leading manufacturer of electronic Potting Compound and silicone raw materials, we optimize the formula for the high-frequency switching, low forward voltage drop, high insulation and fast response requirements of PIN diodes. Unlike ordinary potting silicones, it features ultra-low dielectric loss, does not interfere with fast switching performance, 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 PIN diode chips and ensuring long-term stable operation for procurement partners.
Key Features & Advantages
- Ultra-Low Dielectric Loss & High-Frequency Compatibility: Ultra-low dielectric loss and excellent insulation, ensuring no interference to the high-frequency switching and fast response performance of PIN diodes, maintaining stable electrical performance and signal integrity, which is critical for PIN diode performance in high-frequency communication and switching applications.
- 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 switching of PIN diodes.
- Excellent Thermal Stability & Temperature Adaptability: Operating stably from -60℃ to 220℃, with outstanding high and low temperature resistance; excellent thermal stability ensures no performance degradation of PIN diodes under temperature changes, absorbs internal stress caused by temperature cycles, protecting PIN 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 PIN 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 PIN 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 PIN diode high-frequency switching 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 stability and sealing performance of PIN 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 PIN diode packaging molds or casings.
- Curing: Place the encapsulated PIN 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.
