APEX® Glass is the only glass material that enables the production of burn-in, test socket, and probe card components that require more precise critical dimension control, smaller hole diameters, finer pitches and repeatable alignment.  Our batch manufacturing process is price competitive with other processes like injection molding, manual drilling, and laser drilling.  

APEX® Glass-based components offer many advantages over other materials including:

  • Through holes as small as 200 microns
  • Pitches as small as 1.1x hole diameter
  • Through-holes with aspect ratios up to 10:1
  • Zero micro-fractures ensures higher reliability
  • Create highly complex designs including different sizes of through holes, curved corners, trenches, cavities, linear through holes, and cutouts
  • Leverage the unique glass-ceramic states of APEX® Glass for advanced component designs
  • No expensive tooling requirements reduces prototype costs and turn-around times
