Abstract

The present invention relates to electrically attaching a surface mount device to mounting structure via their respective contact pads using an attach material, such as solder or conductive epoxy, which includes a filler material. In general, the filler material is relatively solid and granular shaped, wherein the diameter of the filler material controls a mounting distance between the surface mount device and the mounting structure. The filler allows a desired distance to be maintained during initial placement of the surface mount device and any subsequent reheating.
