Expert and his associates have experience with processing small features on polyimides, PTFE, and paralene coatings. They have achieved holes as small as 0.001 inches in diameter and can control material removal depth to the submicron range.


In dross-free high pressure cutting, he has successfully cut metals and non-metals at speeds of up to 500 inches per minute (depending on thickness and the thermal properties of the material.) Expert's Firm has achieved accuracies of +/- 0.5 microns. They specialize in cutting medical stents.

Expert and his associates assemble components in a vacuum chamber and guide a laser beam through a window. They achieve hermetic weld-seals equivalent to the vacuum inside the chamber. In the microwelding area, Expert's group has successfully buttwelded wire as small as 0.003 inches and tubing as small as 0.010 inches in diameter.

Expert has a wide background in designing new products and manufacturing processes, primarily in the area of precision mechanical components and assemblies for the computer and aerospace markets, specifically including magnetic recording suspension and actuator assemblies. He has been responsible for getting several products into high volume production, and managing complex projects in high-growth companies.

magnetic recording suspension assembly

Expert has developed a process to weld plates of titanium, hastelloy, nickel, and stainless steel. The process involves several feet of laser weld using pressure and shielding gas at the fusion site. This process allows the plates to be made with 10-20 percent of conventional tooling and cycle times.
