The Leaders in Semiconductor Electron Beam Welding

For more than four decades, Acceleron Inc. has been recognized as one of the industry’s leading providers of electron beam and laser welding, drilling, and cutting services for the semiconductor and microelectronics industries.

With our commitment to high-quality results, fast turnaround times, and unmatched precision, we’ve become a trusted partner and preferred supplier for numerous OEM and Tier-One semiconductor manufacturers.

Our experience spans everything from microelectronic enclosures to MEMS sensors and vacuum assemblies, where even the smallest imperfections can impact performance or reliability.

Precision Welding Services for the Semiconductor Industry

The semiconductor sector demands microscopic precision, thermal control, and clean processing environments. Acceleron’s team of welding specialists combines advanced beam control with decades of engineering expertise to achieve the tight tolerances, repeatability, and purity the semiconductor industry requires.

We specialize in joining delicate materials such as aluminum, copper, stainless steel, Kovar, and nickel alloys, producing defect-free welds with ultra-narrow heat-affected zones (HAZ). This allows critical parts to retain their metallurgical integrity and conductive properties without warping or contamination.

Our electron beam welding technology provides the micro-level accuracy needed to support:

  • Semiconductor manufacturing equipment components
  • Vacuum chambers and wafer processing assemblies
  • MEMS and microsensor housings
  • Heat sinks, chip carriers, and electronic enclosures
  • Power supply and interconnect structures

Old-fashioned values, integrity and unmatched workmanship

  • Large Privately-Owned Facility

    We have 2 buildings with over 45,000 sq ft of combined manufacturing space, and operate two shifts totaling more than 40 employees.
