Process control for full traceability

Our robust proprietary microelectronic manufacturing and process control system ensures real-time organisation wide access to material traceability, inventory management, WIP tracking, SPC, yield reporting and on-time delivery.

Real time throughout and yield tracking

  • Displays throughput and yield by process
  • Can be filtered by Job, Product, Sequence, Site
  • Displayed by Hour/Shift /Day /Week/Month


  • Define work flow.
  • WIP track individual parts.
  • Assemblies must progress through the defined process flow.
  • Ensures operators are trained for processes.
  • ESD controls are auto-enforced.

Detailed item status

  • Parent/child assemblies and sub-assemblies have unique serial numbers for full material control and traceability.

Supply chain resilience
