Inside the Precision of Demo Photoelectric Tech
Where 16 Years of Experience Meets Micron-Level Manufacturing.
Our facility isn't just a factory; it’s a controlled environment where LED diodes are crafted with 16 years of hands-on expertise. Welcome to the heart of Demo Photoelectric Tech.
Controlled Environment for High Yield.
Our core encapsulation is performed in an ISO-certified Class 10,000 cleanroom. We control temperature, humidity, and airborne particles to ensure zero contamination during the sensitive phosphor-dispensing and die-bonding phases.
Micron-Level Consistency
Engineered with micron-level consistency, our LEDs deliver flawless, uniform illumination and exceptional color stability across every single batch.
High-Speed Automated Bonding
Micron-Level Consistency.
Equipped with high-precision automated bonders (ASM/K&S), we achieve consistent electrical connections. Even as a mid-sized firm, we invest in tier-1 equipment to guarantee that every batch of custom diodes meets your exact electrical specs.
Management & Traceability
Every Diode Has a Story.
We utilize a digital tracking system that links every batch to its original wafer bin and production date. This ensures that 3 or 5 years from now, when you need a re-order, we can replicate the exact photometric results you received today.
Bespoke Service Corner
Your Partner in Innovation.
Large factories prefer high volumes; we prefer high precision. Our "Pilot Run" line is designed for custom projects, offering the agility to prototype and adjust spectral bins quickly—perfect for specialized medical, industrial, or architectural lighting needs.
