. Why Potting and Dispensing Technology is Key to LED Manufacturing
LED products need to operate stably in outdoor or humid environments. Potting and dispensing technology is like putting a waterproof protective suit on electronic components. By precisely filling the gaps in the LED module with special adhesives, not only can moisture and dust be isolated, but heat dissipation can also be aided. Common epoxy resin adhesives have high hardness after curing, while silicone adhesives have good flexibility; the choice must be made considering the product's operating environment.
II. A Smart Showdown of Three Mainstream Processes
Needle-tip dispensing: Like a fine paintbrush, suitable for precise coating of tiny areas, with errors controllable within 0.1mm.
Jet dispensing: Like inkjet printing, 3 times faster, suitable for mass production.
Vacuum potting: Vacuuming before dispensing completely eliminates air bubbles, increasing yield by 20%.
III. Three Secrets to Making Adhesive Compliant
Viscosity control: In winter, the adhesive needs to be heated to 25℃; in summer, it needs to be cooled to 18℃ to maintain consistent fluidity.
Path planning: Z-shaped dispensing provides 15% higher coverage than straight dispensing, avoiding missed areas.
Cure monitoring:Ideal curing efficiency is achieved when the UV curing lamp is 10cm away from the adhesive surface.
