Semiconductor Test Hardware Solutions


A critical element of every semiconductor test solution is the interface between the device and ATE. ?The hardware team at Test Spectrum has produced thousands of successful test interface solutions for some of the most challenging semiconductor products on all major ATE platforms. ?Our in-house team of PCB design experts has an added advantage of direct access to our senior test engineering staff.

Test Spectrum provides complete hardware solutions (design, fabrication, and assembly) for all aspects of the semiconductor test industry, including:

  • Final (Package) Test
    Loadboards; Device Interface Boards (DIBs); Handler Interface Boards (HIBs); Handtest Boards
  • Probe/Wafer Sort
    Probe Interface Boards (PIBs); Probe Cards (Cantilever and Vertical)
  • Qualification/Characterization
    Burn-In (HTOL) Boards; HAST Boards; Failure Analysis Boards; Lab Evaluation Boards

Custom Design

Test Spectrum uses a schematic driven process with LVS (Layout Versus Schematic) capability using the latest CAD software tools such as Cadence Allegro (including both OrCad and Concept schematic libraries). We tailor solutions to meet the requirements of each project in a cost effective manner.

  • Extensive experience with complex applications, including RF, mixed-signal, and high speed digital
  • All major ATE platforms supported, including Advantest, Teradyne, Xcerra, and National Instruments STS
  • Design capability for all aspects of semiconductor test (final test, probe, qual)
