Semiconductors

Serving the semiconductor industry is the core of C-Hawk’s identity. We make critical parts and assemblies used to build new tools, as well as to retrofit/remanufacture older tools, that produce semiconductor devices that are integral to many products we use on a daily basis – from vehicles and smartphones to laptops, data centers, and AI-powered systems.

Semiconductor - C-Hawk Technologies

C-Hawk specializes in temperature controlled, high-precision, contamination-free vertical milling and turning of all types of plastics, including PEEK, Ultem, UHMW, and PTFE.

Machining

For new products at the R&D stage or initial low-volume production, C-Hawk’s plastic fabrication provides an excellent manufacturing solution that doesn’t require a heavy investment and extended lead times for tooling.

Fabrication

C-Hawk’s thermoformed and pressure-formed parts typically replace curved or shaped sheet-metal parts that require excessive welding and/or finishing; they can also replace fiberglass and wood. Thermoforming heats a plastic sheet to a pliable forming temperature, forming it to a specific shape in a mold and trimming it to create a usable product. Pressure forming is used on highly detailed parts, exerting 5x the pressure of thermoforming to move material into the detailed areas.

Welding

Developed to drill long, accurate holes in all types of plastic materials when conventional CNC lathe machine capabilities are not adequate for boring holes to extreme depths with precise accuracy. C-Hawk’s gun drilling machine allows for hole diameters from .062” to 1.25” and can accommodate up to 23” lengths, providing customers with more accurate parts, rapid turnaround, and lower cost.

Gold plating is a key feature of metal components used in certain semiconductor capital equipment, allowing for uniform heating and reflectivity throughout a semiconductor chamber. Our products have a direct effect on the silicon wafer and are critical to its overall yield and performance, plating aluminum, brass, and copper substrates for the epitaxy market.

Gold Plating

Nickel plating serves as a tie layer for gold plating. It prevents the diffusion of copper into a part’s gold top layer, as this diffusion can degrade electrical characteristics and contacts’ resistance to corrosion.

As with gold plating, we are a global leader in the chrome plating process. Not merely decorative, chrome plating also adds hardness and contributes to the corrosion resistance of the parts being plated.

Electrochemical anodization is used to convert a metal surface into a corrosion-resistant layer, activating the surface layer to serve as a protective coating for the equipment.

Assemblies

Solvent-bonding plastic involves using a solvent to partially dissolve two surfaces made of similar materials, which become bonded together after the solvent evaporates. Diffusion bonding bonds together like materials at the molecular level through heat and pressure at glass transition temperatures. No solvent is applied, and clear bonds can be made with multiple ports or channels. C-Hawk also offers adhesive bonding and mechanical fastening.
