If you are looking for a quick and cost-effective way to get small holes drilled in almost any substrate, you have come to the right place. Potomac Photonics has the capability to drill precision microholes as small as 1 micron with submicron positional tolerances in a variety of materials such as polymer, metals, ceramics and glass.  Our Engineers will work closely with you to fully understand the requirements for your micro-holes (eg. materials, part thickness, desired feature geometries, taper, etc.) and recommend a process that will satisfy both your prototyping and production needs.

We have extensive experience partnering with Medical Device, Biotech, Electronics and Alternative Energy (solar) companies to help them develop processes to meet some of the most difficult micro-hole drilling requirements in their respective industries.

Applications such as leak testing, probe card drilling, disposable biotech products, and microholes for catheters are just some of the thousands of microhole drilling projects that we have successfully completed.

In addition to laser systems, we have micro-CNC and micro-drilling systems that are capable of drilling micro holes through extremely thick substrates with high precision.
