Implantable Electronics & Neurodevices calculator

Rework Cost Calculator

Use this calculator to estimate rework cost for implantable electronics and neurodevices. It helps compare whether a nonconformance should be reworked, scrapped, contained, or escalated based on expected affected units and rework effort.

What this calculator does

  • Estimate implantable device rework cost from build quantity, rework cost per affected unit, expected rework rate, and fixed setup adders.
  • Use it when manufacturing or quality teams need to cost rework for leads, electrodes, hermetic packages, PCBAs, encapsulation, or final test failures.
  • The result estimates total rework cost for the affected build scope.

Formula used

  • Variable rework cost = build quantity in rework scope × cost per reworked device × expected rework rate
  • Total rework cost = variable rework cost + fixed rework setup and verification adders

Inputs explained

  • Build quantity in rework scope: Use the lot, shift, or campaign quantity that could require rework.
  • Cost per reworked device: Include rework labor, replacement components, retest, inspection, documentation, and material handling per affected device.
  • Expected rework rate: Use the percent of units expected to require approved rework based on the nonconformance or process history.
  • Fixed rework setup and verification adders: Include fixture setup, engineering instructions, validation checks, MRB review, and post-rework verification costs.

How to use the result

  • Use it during MRB review, quote risk assessment, process improvement selection, and cost of poor quality reporting.
  • It assumes rework is approved and technically feasible, and it does not replace validation, regulatory, or quality system disposition requirements.

Common questions

  • What is the rework cost calculator for? It estimates the cost of approved rework for implantable electronics or neurodevice assemblies.
  • What information should I enter? Use build quantity, cost per reworked unit, expected rework rate, and fixed setup or verification adders.
  • What does the result tell me? The result helps compare rework, scrap, containment, and process improvement options.
  • When is the result only an estimate? It is only an estimate until rework instructions, acceptance criteria, retest requirements, and MRB disposition are approved.
