摘要:
A method for manufacturing light emitting devices, comprising: providing a package body including: (i) a reflector cup defining a cavity and (ii) a plurality of metal pads disposed at a bottom surface of the cavity; performing reservoir stencil printing to deposit a respective solder pattern on each of the metal pads, the reservoir stencil printing being performed using a 3D electroform stencil that is placed over the reflector cup, the 3D electroform stencil including a lip configured to engage one or more sidewalls of the reflector cup, and a reservoir extending away from the lip and into the cavity; placing an LED die on the solder patterns that are formed on the metal pads and performing reflow soldering to attach the LED die to the metal pads.
