INTEGRATED CIRCUIT QUALIFICATION
JEDEC JESD47
JESD47 is JEDEC’s stress test qualification standard for integrated circuits. SPACEREL helps chip designers, fabless semiconductor companies, start-ups and component users plan and manage JESD47 qualification across the UK and Europe. We translate your requirements into a practical qualification programme, from initial assessment and test planning through laboratory coordination, results review, failure analysis and reporting. Whether you are launching a new integrated circuit, responding to a customer specification or approaching a qualification deadline, we help establish the evidence you need and the work required to obtain it.
UNDERSTANDING THE STANDARD
What Is JEDEC JESD47 Qualification?
JESD47 is JEDEC’s stress test qualification standard for integrated circuits. It provides a baseline framework for qualifying new devices, product families and relevant changes to products or manufacturing processes.
Qualification uses accelerated stresses to reveal potential device and package failures. Depending on the product, the programme may assess operating life, temperature and humidity resistance, temperature cycling, electrical performance and package integrity.
The applicable requirements depend on the governing revision, device technology, package construction and qualification scope. Existing supplier evidence and the intended application also need consideration.
SPACEREL connects these requirements to a documented programme, helping you establish which tests apply, what existing evidence can support qualification and where further work is needed.
EXPERT ENGINEERING JUDGEMENT
Get Your JESD47 Qualification Plan Right Before Testing Begins
Understanding the standard is the starting point. Applying it requires decisions about test selection, representative samples, qualification families, stress conditions and acceptance criteria.
These decisions affect your budget, sample availability and delivery schedule before testing begins. An unsuitable plan can consume laboratory time and engineering resources while leaving important customer requirements unresolved.
SPACEREL assesses the technical basis of your programme before you commit to testing. We review:
- Applicable requirements: The customer specification, JESD47 revision and supporting test methods.
- Qualification coverage: The device, package and failure mechanisms that need assessment.
- Existing evidence: Whether supplier, process, package or qualification family data can support the programme.
- Sample planning: Production representation, lot selection, quantities and allocation.
- Test conditions and sequencing: Appropriate stresses, preconditioning and measurements.
- Acceptance and investigation: Failure criteria and the approach to unexpected results.
- Application needs: Additional evidence required for the operating environment and service life.
Your team gains a clear plan and specialist support throughout delivery, allowing your engineers to stay focused on developing the product.

SPACEREL can manage your complete qualification programme or support a defined stage. We agree the scope around your product, customer requirements, existing evidence and internal resources.
TEST REQUIREMENTS AND COVERAGE
What Does a JESD47 Qualification Programme Cover?
A JESD47 qualification programme addresses the tests and supporting evidence applicable to your device and package. The final test matrix must reflect the governing revision and product requirements.
Not every test applies to every device. Existing qualification evidence may support some requirements where its relevance and acceptability can be demonstrated.
SPACEREL reviews both the available evidence and the gaps, helping you define a technically justified programme.
| Qualification area | Purpose |
|---|---|
| Operating life and early life behaviour | Assess device behaviour under defined operating stresses and gather evidence relating to early failures. |
| Temperature and humidity stresses | Evaluate susceptibility to mechanisms associated with heat, moisture, corrosion and related effects. |
| Temperature cycling | Assess the response of the device and package to repeated temperature changes and associated mechanical stresses. |
| Electrical parameter assessment | Evaluate relevant electrical characteristics against specified limits and temperature requirements. |
| Electrostatic discharge and latch-up | Assess device susceptibility using the applicable methods and classifications. |
| Non-volatile memory endurance and retention | Evaluate cycling endurance, data retention and relevant memory operating conditions. |
| Package integrity | Assess applicable interconnect, mechanical, solderability, sealing and construction characteristics. |
| Technology and wearout evidence | Review supporting evidence for relevant long-term failure mechanisms. |

UK-BASED · WORKING ACROSS EUROPE
JESD47 Support for Chip Designers, Fabless Companies and Component Users
SPACEREL supports teams that need specialist qualification expertise, additional engineering capacity or a partner to manage the complete programme.
For chip designers and fabless companies, we help connect design, foundry, assembly and test evidence into a coherent qualification approach.
For start-ups, we establish the requirements and programme structure when an internal qualification function is not yet in place.
For component users and hardware developers, we assess supplier evidence against procurement and application needs, identifying where additional information or testing is required.
For space hardware teams, we assess how JESD47 evidence contributes to the wider component assurance programme and identify additional mission-specific requirements.
We support UK and EU customers with requirements assessment, qualification planning and programme coordination. The scope can range from reviewing an existing report to managing qualification from initial requirements through final assessment.
QUALIFICATION DECISIONS EXPLAINED
Planning Your JESD47 Qualification
The following questions address common decisions before a JESD47 qualification programme begins.
Which JESD47 revision should our project use?
The governing revision should be established from your contract, customer specification and qualification requirements before the programme is agreed. SPACEREL can clarify the applicable documents and assess how revision differences affect the work.
Do we need every test listed in JESD47?
Not every test applies to every device. Selection depends on the technology, package, qualification scope and available evidence. SPACEREL documents the basis for test selection so the programme addresses the relevant requirements.
Can existing supplier or qualification family data be used?
Existing data may support qualification where it satisfies the applicable requirements and represents the device, process or package being assessed. We review its relevance, completeness and limitations before recommending additional testing.
How long does JESD47 qualification take?
The schedule depends on the selected tests, stress durations, sample readiness, test hardware, laboratory availability and any investigation required. We assess these dependencies when developing the programme and identifying the critical activities.
Does passing JESD47 testing demonstrate the required service life?
Passing the applicable tests provides evidence under defined conditions. Demonstrating a particular service life requires consideration of operating conditions, acceleration models and relevant failure mechanisms. Additional reliability evidence may be necessary.
Does JESD47 qualification establish suitability for space?
JESD47 qualification alone does not establish suitability for a space mission. Space programmes may require additional radiation assurance, mission-specific reliability assessment, screening and other component assurance activities.
Does JESD47 qualify a complete circuit board or finished product?
JESD47 addresses integrated circuit qualification. Board-level interconnections, assembly effects and finished equipment requirements need separate consideration. SPACEREL helps define the boundary between component evidence and the wider qualification programme.
What happens if a device fails during qualification?
The failure must be assessed to understand its cause and significance. Depending on the findings, the next steps may include failure analysis, corrective action, additional testing or requalification. SPACEREL supports the investigation and documents the technical basis for those decisions.
Can SPACEREL manage the complete qualification programme?
Yes. SPACEREL provides requirements assessment, qualification planning, testing and laboratory coordination, results review, failure analysis and reporting. The scope is agreed around your product and project needs.
