Product Overview
Our Electronic Potting for Laser Diodes is a professional Silicone Potting Compound developed for the encapsulation, sealing, heat dissipation and protection of Laser Diodes. As a leading manufacturer ofelectronic Potting Compound and silicone raw materials, we optimize the formula for laser diodes’ core needs—low optical loss, high-power heat dissipation and anti-vibration. Unlike ordinary potting silicones, it maintains low optical loss after curing, does not interfere with laser transmission, efficiently dissipates heat to avoid chip burnout, resists corrosion and ozone, and has excellent adhesion to PC, PMMA, PCB and metals, effectively protecting laser diode chips and welding wires, ensuring long-term stable laser emission for procurement partners.
Key Features & Advantages
- Low Optical Loss & Laser Compatibility: Low optical loss (≤0.1%) after curing, ensuring no obstruction to laser transmission and maintaining stable laser intensity and wavelength; high transparency and light transmittance, avoiding laser scattering or absorption, which is critical for laser diodes’ emission performance and application accuracy.
- Superior Heat Dissipation & Temperature Adaptability: Operating stably from -60℃ to 220℃, with outstanding high and low temperature resistance; integrated thermally conductive potting compound properties accelerate heat dissipation of high-power laser diode chips, avoiding overheating damage and extending service life; absorbs internal stress from temperature cycles, protecting laser diode chips and welding wires.
- Ultra-High Insulation & Anti-Vibration: Ultra-strong insulation performance (dielectric strength ≥25 kV/mm, volume resistivity ≥1.0×10¹⁶ Ω·cm), preventing short circuits and ensuring safe operation; excellent anti-vibration and shock-resistant effects, protecting laser diodes from mechanical damage during transportation and use; waterproof, moisture-proof and dust-proof, adapting to harsh industrial environments.
- Strong Adhesion & Easy Operation: Excellent adhesion to PC (electronic insulation board), PMMA (acrylic), PCB and metals (aluminum, copper, stainless steel), 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 laser diode production.
- High Stability & Dual-Formula Options: Available in high-purity addition curing silicone (low volatility, non-toxic, high stability) and enhanced thermally conductive potting compound (for high-power laser diodes), meeting different power and application needs; 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, reducing waste and 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, optical loss and adhesion, which is crucial for laser diode’s emission performance.
- 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 optical loss, heat dissipation and sealing performance of laser 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 laser diode packaging molds or casings.
- Curing: Place the encapsulated laser 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.
