Micro-Soldering Fixture
Precision MicroFab designed and manufactured an entirely new proof-of-concept micro-wire fixture device to facilitate a micro-soldering process. This micro-positioning device will clamp and manipulate the wire leads of the quad…
Laser Ablate Parylene Coating
Our client sent us gold plated pins coated with parylene for selective removal. We carefully stripped off the parylene in a small window by ablating the coating with our deep…
R&D for Assembly of Micro-manufactured parts
Precision MicroFab worked closely with a medical device manufacturer to build a microscopic prototype clevis fastener system. It consists of three minuscule parts- the clevis, clevis pin and tang. The…
Quantum Particle Nozzle
The Joint Quantum Institute at the University of Maryland needed an array of 480 holes, 50 microns in diameter, an inch deep, all pointing to a focal point 27 cm…
Die Drilling Production Laser
Precision MicroFab™ designed, manufactured and installed an entirely new production-level laser system to drill diamond carbide and thermally stable diamonds. This system replaced a legacy system and considerably reduced run…
James Webb Catenary Cable
Congratulations to NASA, NGC and ManTech on the successful deployment of the James Webb Space Telescope, especially unfurling the sunshield. The James Webb will replace the Hubble Space Telescope and…
Quantar Sensor
Precision MicroFab™ was contacted by the Heliophysics Science Division from NASA’s Goddard Space Flight Center to develop a complex hole array drilled into a domed surface. The Goddard Space Flight…
Linear fiber ferrule
Precision MicroFab worked with NASA to build a better fiber ferrule that would be implemented in one of their newest sensors. Light enters the fiber optic cable through a close…
Micro-molding
This is a micro-mold of a micro-fluidic mixer suitable for high volume production by hot embossing and cast silicone methods. The part was cut and joined via laser. The channels…
Micro-channels in sapphire
This micro-channel, laser milled into sapphire, is 90 µm deep by 75 µm wide. Note the square profile and flat bottom shown in the end view. If you’d like more…
Micro-welding tube
We use lasers to micro-weld and micro-solder at a very small scale. These micrographs show a 0.900 mm stainless steel tube with a 0.150 mm wall thickness. Precision MicroFab clamped…
Micro-soldering
These 50 µm wide leads are laser soldered onto a thin metalized layer deposited on a ceramic substrate. If you’d like more information on this project or if you’re interested…
Micro-hole array
This micrograph shows an array of holes laser drilled entirely through a 1.0 mm thick microscope slide. The hole diameters are 26-29 µm at the top and taper down to…
