Abstract
An interdigitated chip capacitor (“IDC”) assembly including an IDC having a semiconductor block with a top portion, a bottom portion opposite the top portion, a plurality of sidewall portions extending between the top and bottom portions, and a plurality of terminals located on the sidewall portions; and a substrate having a top portion with a plurality of generally flat, vertically extending, nonconductive abutment surfaces thereon, the sidewall portions of the IDC being abuttingly engaged with at least some of the plurality of abutment surfaces.
Claims20
An interdigitated chip capacitor (“IDC”) assembly comprising:
- an IDC comprising:
- a semiconductor block with a top portion, a bottom portion opposite said top portion and a plurality of sidewall portions extending between said top and bottom portions;
- and
- a plurality of terminals located on said sidewall portions;
- and
- a substrate comprising a top portion with a plurality of nonconductive vertically extending abutment surfaces thereon, said sidewall portions of said IDC being abuttingly engaged with at least some of said plurality of abutment surfaces.
A method of registering terminals on an interdigitated chip capacitor (“IDC”) with contact pads on a substrate comprising:
- forming at least one vertically extending nonconductive abutment surface between adjacent ones of the contact pads;
- and
- urging at least one sidewall portion of the IDC into abutting engagement with the at least one abutment surface on the substrate.
A method of preventing solder that connects a terminal on an interdigitated chip capacitor (“IDC”) with a contact pad on a substrate from causing short circuits between adjacent terminals comprising:
- forming a solder strip on the contact pad;
- isolating at least one of the solder strip and the terminal from adjacent solder strips and terminals.
