Micrometer scale components
View Patent ↗Micrometer scale components comprise a component body comprising an alloy of a first solder metal and a second solder metal, the alloy having a higher liquidus temperature than the second solder metal; and a base region of the structure body wetted to a substrate, wherein the component body has a molded surface profile.
1. A hard drive, comprising:
a magnetic disk;
a write head disposed over the magnetic disk and comprising a laser directed at a catoptric structure;
the catoptric structure oriented to direct laser light energy from the laser to the magnetic disk, the catoptric structure comprising:
a structure body comprising an alloy of a first solder metal and a second solder metal, the alloy having a higher liquidus temperature than the second solder metal;
a catoptric face formed on a first surface of the structure body; and
a base region of the structure body wetted to a substrate.
2. The hard drive of claim 1 , wherein the alloy comprises a heat sink material.
3. The hard drive of claim 2 , wherein the catoptric face has a surface roughness less than about 0.5 microns.
4. The hard drive of claim 1 , wherein the first solder metal and the second solder metal comprise In, Sn, Ag, Au, Ge, Ga, Bi, Cu, or Pb.
