[0002] During the production and processing of LED lamp beads, die-bonding and dispensing equipment is required. Die-bonding is generally used to encapsulate components such as LED lamp beads, circuit boards, and transistors, and typically appears as a transparent solid. Dispensing, on the other hand, is typically used to bond mechanical parts, electronic components, and other items, and appears as a thin liquid. Dispensing typically relies on light- or heat-sensitive curing, a chemical reaction that is slower than die-bonding. Dispensing can also be selected as a single or two-component adhesive to suit different industrial applications.
