Implantable Electronics & Neurodevices calculator

Final Electrical Test Capacity Calculator

Use this calculator to estimate final electrical test capacity for implantable electronics and neurodevices. It converts tester fixture output, planned cycles, station uptime, and first-pass yield into expected good devices available for release.

What this calculator does

  • Estimate good implantable devices per shift from tester throughput, planned cycles, uptime, and first-pass yield.
  • Use it when test engineering or production control needs to know whether final electrical or functional test capacity can cover a release plan.
  • The result estimates good devices that can clear final electrical test in the planning window.

Formula used

  • Gross final electrical test capacity = devices tested per fixture cycle × planned final test cycles
  • Good final electrical test capacity = gross capacity × final test station uptime × final electrical test first-pass yield

Inputs explained

  • Devices tested per fixture cycle: Use the number of pulse generators, sensors, receivers, or modules that can complete the test sequence per cycle.
  • Planned final test cycles: Use scheduled tester cycles for the shift or day after accounting for test duration and fixture availability.
  • Final test station uptime: Use recent uptime for the tester, fixture, software, probes, cables, and support equipment.
  • Final electrical test first-pass yield: Use the recent first-pass yield for this product, firmware, test script, and release configuration.

How to use the result

  • Use it to schedule testers, justify fixture duplication, plan release timing, or identify capacity gaps before packaging.
  • It does not include engineering debug time, retest loops, test software validation, or downstream sterile packaging constraints.

Common questions

  • What is the final electrical test capacity calculator for? It estimates how many good implantable devices can pass final electrical or functional test in a shift or planning window.
  • What information should I enter? Use devices per cycle, planned cycles, station uptime, and first-pass yield from the same tester population.
  • What does the result tell me? The result shows expected good tested devices, plus losses from uptime and yield assumptions.
  • When is the result only an estimate? It is only an estimate when test duration, firmware revision, fixture availability, or retest behavior changes.
