Potomac Photonics provides precision bonding and assembly services for miniature components, supporting projects from rapid prototyping through scalable production. Our capabilities enable highly accurate joining of small metal and plastic parts, with epoxy dot placement as small as 150 µm and tightly controlled laser-based joining processes.
Effective bonding and assembly at the microscale require components to be held in precise alignment under controlled force while a localized heat source is applied to the joint area. Focused laser energy is ideally suited for this task, allowing material to be joined with minimal thermal impact to surrounding features. By carefully managing laser energy, pulse duration, and fixturing, we achieve high-yield, repeatable results for complex micro-assemblies.
These capabilities make laser bonding and precision assembly an enabling technology for applications where dimensional accuracy, material integrity, and process consistency are critical.
Micro-Bonding and Assembly Technologies
Laser Micro-Welding
Laser micro-welding is an advanced joining method that enables high-precision bonds across a range of metal and organic materials. At Potomac Photonics, we employ pulsed infrared lasers to ensure consistent, controlled welds with excellent repeatability. To optimize results, we carefully manage laser energy and pulse duration while ensuring proper fixturing for part accuracy
Precision Epoxy Dispensing
For assembly of electronic and optical devices, precision epoxy dispensing offers a highly effective approach. We are capable of placing epoxy dots with diameters as small as 150 microns, and we work with encapsulation and underfill materials to enhance assembly strength and performance.
Material Compatibility
We provide bonding and assembly for a broad selection of materials, including:
Our laser welding systems are tuned for microfabrication, enabling precise joins on both flat and tubular components.
