1. A method of bonding an electrical component to a substrate comprising:
- applying solder paste on to a substrate;
urging a solder preform into contact with the solder paste, the solder preform having an aperture is formed therethrough, such that solder paste is urged through the aperture; and
urging an electrical component into contact with the solder preform and into contact with the solder paste that has been urged through the aperture, thereby bonding the electrical component, the solder preform, and the substrate together to define a reflow subassembly.

Abstract
A method of bonding an electrical component to a substrate includes applying solder paste on to a substrate. Solder preform has an aperture is formed therethrough and is then urged into contact with the solder paste, such that solder paste is urged through the aperture. An electrical component is then urged into contact with the solder preform and into contact with the solder paste that has been urged through the aperture, thereby bonding the electrical component, the solder preform, and the substrate together to define a reflow subassembly.

9. A method of bonding a MEMS device to a substrate comprising:
-
applying solder paste on to a substrate; urging a solder preform into contact with the solder paste, the solder preform having an aperture formed therethrough, such that a limited amount of solder paste is urged through the aperture; and urging a MEMS device into contact with the solder preform and the solder paste that has been urged through the aperture, thereby bonding the electrical component, the solder preform, and the substrate together to define a reflow subassembly. - View Dependent Claims (10, 11, 12, 13, 14, 15)
