Joints soldered with cored wire are consumed in a variety of lighting applications. Most commonly, these spools of cored solder wire are used to make the connections between the control / power driver board and the LED engine board shown in Figure 1, to make board to board connections for linear lighting and for soldering the end cap contact which serves as the electrical gateway for retrofit based bulbs as shown in Figure 2.

LED chip-on-board applications (COB) typically involve assembling an LED die stack directly on to a substrate such as Metal Core PCB (MCPCB), FR4 etc.

A variety of die attach materials, including solder, conductive adhesive, or sintered materials can be used to bond the LEDs to the substrate, depending on the specific requirements, and the tradeoffs involved.
