Industry Challenges
Mini/MicroLED micro-pads are highly prone to bridging and short circuits caused by insufficient solder.
High-power modules face severe thermal dissipation pressure; high void content accelerates luminous decay and dead LEDs.
Aluminum PCBs have high thermal capacity, which easily leads to poor wetting and cold solder joints.
Mass transfer mounting for display backlighting requires high yield and stability in mass production.
Core Advantages
Ultra-fine Particle Precision Printing
Compatible with Mini/MicroLED micro-pads, it resists slumping, suppresses bridging, and supports mass pixel mounting production.
Low Voiding, High Thermal Conductivity
Controllable void content, excellent thermal conductivity, quickly dissipates chip heat, delays LED luminous decay, and reduces the risk of dead LEDs.
Excellent Wetting on Aluminum PCBs
Formula optimized for the high thermal capacity of aluminum PCBs, it removes pad oxidation, ensures full solder coverage, and reduces cold and missed solder joints.
Wide Reflow Process Window
Compatible with direct-lit backlighting and high-power luminaires, it reduces thermal shock to LED chips and is compatible with various PCB surface finishes.
Low Residue, High Insulation
Low Flux residue with good insulation performance prevents leakage between micro-pixels and ensures stable display performance.
