Competency level

Foundation

Name the variables, units, artifacts, and evidence classes required to read the role path.

1.1

Map packaging and test flow

Map bonding, assembly, singulation, probe, package test, reliability, and failure-analysis handoffs.

Prerequisite: Start here
Evidence boundary: A lifecycle map is not an executable assembly or qualification plan.

Public artifact tasks

lessonPackaging and test reliabilityList the lifecycle stages and evidence needs.mapPackaging, test, and reliability domainLocate the public domain lane.

1.2

Calculate a package proxy

Calculate a bounded package parasitic or delay proxy and record geometry, units, assumptions, and exclusions.

Prerequisite: Map packaging and test flow
Evidence boundary: A proxy cannot replace extracted package models or measured characterization.

Public artifact tasks

calculatorEngineering calculatorsUse a bounded calculator with explicit assumptions.simulationPackaging and test evidence atlasLocate the proxy in the wider evidence chain.

Competency level

Cross-domain practice

Trace and compare bounded public replays across at least one engineering handoff.

2.1

Compare packaging evidence states

Compare two packaging atlas states and explain which assembly, test, or evidence condition changed.

Prerequisite: Calculate a package proxy
Evidence boundary: The atlas does not predict qualification, yield, or product reliability.

Public artifact tasks

simulationPackaging and test evidence atlasCompare fixed public states.labPackaging and test labRecord the changed condition and limitation.

2.2

Trace bonding and HBM handoffs

Trace one hybrid-bonding readiness factor into an HBM or base-die partition question while marking missing measurement evidence.

Prerequisite: Compare packaging evidence states
Evidence boundary: The trace does not establish bond quality, assembly readiness, or HBM performance.

Public artifact tasks

labHybrid bonding readinessIdentify a bounded mechanical readiness factor.labHBM base-die partitionTrace the factor into a partition or test question.

Competency level

Evidence-ready

Construct an inspectable evidence record with limitations, stop conditions, and replacement needs.

3.1

Evaluate qualification evidence

Evaluate whether a packaging or test statement is backed by replay, source metadata, measured evidence, or an unresolved replacement slot.

Prerequisite: Trace bonding and HBM handoffs
Evidence boundary: Source presence does not establish qualification or employer acceptance.

Public artifact tasks

3.2

Construct a packaging handoff

Construct a handoff with artifact, metric, method, grain, uncertainty, limitation, stop condition, and next evidence need.

Prerequisite: Evaluate qualification evidence
Evidence boundary: A complete record is not a qualified package, test program, or reliability decision.

Public artifact tasks

workspaceEvidence provenanceTrace artifact and release lineage.trustCorrectionsRecord a public boundary correction when required.

Role boundary

Evidence first. Career promises stay out.

This path is an evidence-reading guide and does not provide assembly recipes, test limits, qualification plans, or reliability disposition.

Role paths are educational navigation. They do not certify competence, promise employment, rank candidates, or represent employer acceptance.
