Microfocus X-ray inspection in electronics industry
The microfocus X-ray inspection of electrical interconnects in semiconductor and electronics production has become a standard after the introduction of electronic packages like Ball-Grid-Arrays (BGA) and Quad-Flat-No-Leads-Packages (QFN).

Increasingly complex products like Package on Package (PoP) or Fine Pitch Ball Grid Array Stacked Die (FBGA-SD) have intensified the requirements regarding accuracy and resolution. Also assembled and bare multilayer printed circuit boards (MLPCBs) with up to 48 layers or printed circuit boards with embedded layers of copper require special testing facilities that are equipped with powerful microfocus X-ray tubes.

Typical Applications

Non-destructive X-ray inspections in electronics industry

Non-destructive microfocus X-ray inspection in electronics industry, e.g.:
  • Ball Grid Arrays (BGA), integrated circuits (IC), bond wires
  • Semiconductor packaging (diodes, wafer bumps, copper)
  • Shielded devices, housings, complete modules
  • Wafer-level chips scale packages (WLCSP)
  • Quad-Flat-Packages no-leads (QFN), similar components
  • Printed circuit boards, hidden interconnects
  • Bare boards, multilayer boards
  • Power modules, IGBT modules
