How to assemble an LED
This is a guide on how to assemble an LED.
It requires the following: an LED chip, a leadframe, a conductive attaching material, bonding wire, optional phosphor and epoxy.
A high brightness LED will require a heatsink.
A major step is component attach, also known as die attach. A conductive silver paste can be used.[1]
There will for example be a ceramic H-frame.[1] It can be attached to a ceramic LED substrate which is at the base.[1] The H-frame can be epoxy attached to the base using, for example, Ablestik 84-3 adhesive.[1]
LED chips can be epoxy attached to the ceramic base using 84-1LMISR4, for example.[1]
Each LED can be interconnected using two 32 micron gold wires, for example.[1] The wires can be encapsulated using GE IVS4632 silicone, for example.[1]
