Patent ID: 8288175

Claim:
A method of manufacturing an integrated circuit (â€œICâ€) package comprising radio frequency (â€œRFâ€) components, the method comprising: electrically connecting a printed circuit pattern on an external major surface of an IC assembly to an RF testing motherboard by bringing them together with an interposed adaptor layer, the adaptor layer comprising a double-sided printed circuit board (â€œPCBâ€) with conductive vias between its printed circuit layers; RF testing the IC assembly using the RF testing motherboard, whilst RF tuning components of the IC assembly; and separating the IC assembly and connecting its major surface to a solder ball grid array (â€œBGAâ€) which has substantially the same RF impedance as the adaptor at RF signal paths from the IC assembly to the BGA; wherein the adaptor layer substantially simulates an impedance of the BGA at the RF wavebands over which the IC assembly operates.
