Abstract
A method of accurately placing an object with a pick and place machine provides raw material. A desired surface topography is created in the raw material. The raw material is diced into parts using a bevel cut so that each of the parts has bevel surfaces. A fixture is provided that has a plurality of spaced cavities with each cavity having bevel surfaces constructed and arranged to mate with the bevel surfaces of an associated part. A pick and place machine picks and places each part into an associated cavity such that the bevel surfaces of the part mates with the bevel surfaces of the cavity.

A method of accurately placing a part during a manufacturing process, the method including:
- providing raw material,
- creating a desired surface topography of the raw material,
- dicing the raw material into parts using a bevel cut so that each of the parts has bevel surfaces,
- providing a fixture having a plurality of spaced cavities, each cavity having bevel surfaces constructed and arranged to mate with the bevel surfaces of an associated part, and
- placing each part into an associated cavity such that the bevel surfaces of each part mate with the bevel surfaces of the cavity.
A method of accurately placing a part with a pick and place machine, the method including the sequential steps of:
- mounting raw material onto a silicon wafer frame,
- structuring the raw material to create a certain surface topography,
- flipping and transferring the raw material onto adhesive tape such that the structured portion of the raw material engages the adhesive tape,
- dicing the raw material into parts using a bevel cut so that each of the parts has bevel surfaces,
- providing a fixture having a plurality of spaced cavities, each cavity having bevel surfaces constructed and arranged to mate with the bevel surfaces of an associated part,
- using a pick and place machine to pick, flip and place each part into an associated cavity such that the bevel surfaces of each part mate with the bevel surfaces of the associated cavity,
- surrounding each part with adhesive to build a base for the part,
- curing the adhesive to define a structure,
- applying a lithography process to build up metallization on the structure, and
- dicing the structure to defined individual pieces.
