Method of attaching an electronic device to an MLCC having a curved surface
View Patent ↗A method of forming an electrical component is provided. The method comprises preparing a subassembly by electrically connecting an integrated circuit to a flexible circuit; and attaching the subassembly to a multilayer ceramic capacitor having a mounting surface with a curvature deviation exceeding 0.008 inches per inch.
1. A method of forming an electrical connection comprising:
providing a capacitor wherein said capacitor has a mounting surface with a curvature deviation exceeding 0.008 inches per inch;
providing an electronic component;
forming a conductive column comprising conductive balls between said capacitor and said electronic component wherein said conductive column has a height which is at least as large as a sum of said curvature deviation, a stand-off distance between said capacitor and said electronic component and a compression distance;
and
bonding said capacitor to said electronic component through said conductive column.
2. The method of forming an electrical connection of claim 1 wherein said bonding is selected from reflow bonding, thermosonic bonding, wire bonding, bump bonding, plate-up, pin attach, ball attach adhesive attach.
3. The method of forming an electrical connection of claim 1 wherein said electronic component comprises a flexible circuit.
4. The method of forming an electrical connection of claim 3 wherein said flexible circuit comprises an integrated circuit mounted thereon.
5. The method of forming an electrical connection of claim 4 wherein said flexible circuit further comprises at least one secondary component.
6. The method of forming an electrical connection of claim 5 wherein said secondary component is selected from the group consisting of current limiter, varistor, sensor, fuse, thermistor, resistor and inductor.
