Implantable Electronics & Neurodevices calculator
Micro-Weld Inspection Load Calculator
Use this calculator to estimate how much inspection time a lot of implantable micro-welds will consume. It is useful for neurostimulator headers, lead connections, battery tabs, titanium can welds, and other small joints where visual or automated inspection capacity can become the bottleneck.
What this calculator does
- Estimate inspection time for implantable device micro-welds using weld count, inspection rate, and handling allowance.
- Use it when production or quality teams need to staff microscope, vision, or pull-test inspection for laser welds, resistance welds, lead bonds, or feedthrough joints.
- The result estimates total inspection minutes needed for the weld lot.
Formula used
- Base micro-weld inspection time = micro-welds requiring inspection ÷ verified inspection rate
- Required micro-weld inspection time = base micro-weld inspection time × allowance factor
Inputs explained
- Micro-welds requiring inspection: Use the number of laser welds, resistance welds, bond joints, or feedthrough welds in the lot.
- Verified inspection rate: Use a recent microscope, vision system, or destructive sample inspection rate for this weld type.
- Inspection handling allowance: Add time for fixture loading, image saving, DHR entry, suspect weld review, and retest.
How to use the result
- Use it to plan inspector staffing, microscope time, vision cell capacity, or lot release timing.
- It assumes the inspection rate is valid for the weld type and does not include engineering disposition time for failed welds.
Common questions
- What is the micro-weld inspection load calculator for? It estimates the inspection minutes needed for implantable device micro-welds.
- What information should I enter? Use weld count, verified inspection rate, and the allowance for handling, image capture, records, or retest.
- What does the result tell me? The result helps size inspection labor and decide whether weld inspection will delay lot release.
- When is the result only an estimate? It is only an estimate when weld complexity, operator training, microscope setup, or defect review time differs from the historical rate.
