Patent ID: 7311240

Claim:
A method for electrically inter-connecting an optical subassembly with a printed circuit board via a flexible circuit board that can be disposed within the housing of an optical transceiver module, the method comprising the steps of: electrically connecting a first end of a flexible circuit board to a printed circuit board, the electrical connection comprising the steps of: (a) placing a quantity of solder on a pad region disposed on a top surface of the printed circuit board; (b) placing a button extending a predetermined distance from a surface of the flexible circuit board at the first end within a hole formed in the solder, such that a lower surface of the button contacts the pad of the of the printed circuit board; (c) applying a heat source and heating at least one of said flexible circuit and said printed circuit board until said quantity of solder liquefies; (d) removing said heat source until said solder solidifies, said solder having a uniform thickness approximately equal to the predetermined distance; and electrically connecting a second end of a flexible circuit board to an optical subassembly, the electrical connection comprising the steps of: (e) repeating steps (a)-(d) at the second end of the flexible circuit board to electrically connect it to the optical subassembly.
