Abstract:
A method for making a circuit board assembly comprising the steps of:providing a first circuit board portion including a first conductive member having a top surface; providing a second circuit board portion having a bottom surface; removing a portion of said second circuit board portion from a first region which is to form an aperture within said circuit board assembly; selectively forming at least one first annular groove within said top surface of said first conductive member, said at least one first annular groove being disposed around said first region; applying an adhesive material to selective portions of said bottom surface of said second circuit board portion; attaching said second circuit board portion to said first circuit board portion such that said adhesive material resides at least partially between said second circuit board portion and said first conductive member; and performing a laminating process upon said second circuit board portion and said first circuit board portion, said laminating process being effective to cause said adhesive material to liquefy, said at least one first annular groove being effective to entrap at least a portion of said liquefied adhesive material, thereby substantially preventing said liquefied adhesive material from entering said first region of said second circuit board which is to form said aperture.
