All modern industries experience the need for smaller and smaller
parts. Manufacturers of electronics, medical devices and components,
computers and parts, avionics, etc., have a need for parts of
miniature sizes and complex shapes and
hole
patterning. They are made by a variety of methods.
Laser hole drilling outperforms wire EDM, chemical etching,
mechanical machining/cutting, electroforming, and other processes
because the process is non-contact and flexible.
In addition, there are fewer process limitations, no need for
expensive waste disposal, and tooling costs are reasonable. High
quality cuts with exceptional positional and feature size tolerances
are achieved. LLTI developed laser-based hole drilling technology to
satisfy the growing need for smaller products.

Applications:
Our expertise covers wide range from drilling ports in catheters,
irrigation needles, precise orifices for oxygen regulators, fuel
injectors, arrays of holes with conical shape for drug dispersion,
filters with precise ratio of openings area for embolic filters,
angioplasty, as well as drilling holes in long (10 to 20 feet)
irrigation pipes.

Materials:
Materials such as stainless steel, aluminum, brass, silicon,
ceramics, polyimides, nylon, are ideal for
laser hole drilling.

Specifications and
Tolerances:
In general, the resolution of features produced by
laser micro-hole drilling is proportional to the wavelength used
and beam quality. LLTI uses almost diffraction-limited beams and
large numeric aperture lenses, or imaging techniques to form and
drill the specific shapes. Two-micron features are achievable on
some materials. Our lasers provide a depth-of-field sufficient to
machine relatively thick materials. Positional accuracy on a single
micron level allows us to make unique parts not achievable using
conventional methods.
