Die sintering on ceramic substrates

Die sintering on ceramic substrates

Core application involving the bonding of SiC/IGBT/MOSFET dies to substrates (DBC or AMB). It supports the simultaneous sintering of diverse components (e.g., NTC thermistors, IGBR resistors, clips, spacers, and pillars) within a single production cycle.

An AMX classic process

Years of experience have enabled our specialist to develop refined skills in managing these applications.
Thanks to this know-how, AMX is able to provide comprehensive support throughout the entire assembly process.

Main process workflow is:
  • Plasma cleaning of substrates and die backside
  • Stencil printing on substrate with custom stencil (3D stencil printing available)
  • Drying in a nitrogen (N₂) oven
  • Pick and place of dies over paste using hot tacking process to keep the dies in position
  • Sintering in N₂ atmosphere using our Micropunch system or flat tool with buffer materials
  • Scanning Acoustic Microscopy (SAM) analysis
  • Shear test analysis

AMX is also experienced in assembly and sintering of:
  • Spacers
  • Gate resistors
  • NTC
  • Metallized piezoelectric sensors
  • Lead frames
