Patent ID: 8218330

Claim:
A reworkable passive element embedded PCB (printed circuit board) comprising: a board member comprising first and second through holes spaced apart from each other; first and second fillings buried in the first and second through holes, respectively, said first and second fillings formed of a reflowable conductive material that melts in a reflow process; a removable first passive element having first and second electrodes; and a first insertion groove formed in an upper surface of the board member between the first and second through holes and between portions of the first and second fillings, wherein said first passive element is mounted in the first insertion groove, the first passive element having a bottom surface contacting the board member, the first electrode having a bottom surface and a side contacting the first filling, and said second electrode having a bottom surface and a side contacting the second filling, the first and second fillings at least partially embedding the removable first passive element in the PCB, and wherein the first passive element has an exposed upper surface that is not in contact with another structure, enabling removal of the first passive element upon melting of the reflowable conductive material in response to the reflow process.
