Abstract:
1. A method of forming a package structure of photodiode, the method comprising: providing a heat-dissipation plate; forming a patterned solder layer on the heat-dissipation plate, wherein the patterned solder layer is for connecting the heat-dissipation plate and a circuit board; placing the circuit board on the heat-dissipation plate, the circuit board including: placing a carrier having a metal cladding surface into the opening; placing a photodiode chip on the carrier, wherein the bottom area of the photodiode chip is less than the metal cladding surface such that a portion of the metal cladding surface is exposed; conducting a single reflow process to solder the circuit board, the heat-dissipation plate, the carrier and the photodiode chip together; and electrically connecting the exposed metal cladding surface to the first contact pad.
