Engineering Process & Verification
How SIMORCHIP controls quality, builds each product and verifies it on the target platform.
Standards & Specifications
Industrial memory configurations are specified against applicable JEDEC requirements. Product-specific electrical, timing, mechanical and environmental parameters are defined in each product datasheet.
Published Specifications
Applicable standards provide a defined reference for electrical, timing, mechanical and SPD-related requirements. Final product parameters are stated in each product datasheet.
Operating Configuration
Qualification references the operating configuration approved for the target platform, as supported by platform firmware and the memory controller.
Compatibility & Verification Reference
A defined industry specification provides a common technical reference when comparing module configurations. Compatibility depends on the target configuration, and requalification requirements depend on the scope of change.
Product-Specific Operating Conditions
Operating-temperature requirements are defined at product level. The applicable range should therefore be confirmed against the datasheet for the specific module or drive under evaluation.
Quality Control
Quality-control activities are applied across incoming material, in-process manufacturing, finished-product inspection and outgoing shipment verification.
IQC — Incoming Quality Control
Incoming materials are checked against procurement, configuration and acceptance requirements before they enter production.
IPQC — In-Process Quality Control
In-process checks are performed at defined manufacturing stages to identify process deviation before completion of the production lot.
FQC — Final Quality Control
Finished products are reviewed against applicable product specifications and defined inspection requirements prior to release for shipment preparation.
OQC — Outgoing Quality Control
Outgoing inspection verifies applicable shipment information, including product identification, quantity, labeling and packaging requirements before dispatch.
Automated Functional Testing
Automated test equipment is used where applicable to verify module or drive functionality against defined production requirements.
Inspection Stations
Final inspection reviews product identification, appearance and recorded test results before products are approved for packing.
Manufacturing Process
Manufacturing sequence varies according to product architecture and form factor. The following process routes summarize the principal control stages used for memory and storage production; individual steps apply where applicable to the approved production route for a given product.
Material Control
Incoming material checked and released to production
- Incoming material
- IQC inspection
- Material confirmation
- Warehouse control
SMT Assembly
Components mounted and soldered to the module
- Component placement
- SMT inspection
- Soldering inspection

- Visual inspection
SPD Programming & Functional Verification
Module descriptor programmed and module function verified
- SPD programming
- SPD verification
- Module parameters verified against the part specification
Final Inspection & Product Identification
Finished module reviewed against its specification
- Final inspection

- Appearance inspection
- QC sampling
Packing & Release
Packed and released against the order
- Packing
- Packaging inspection
- Carton packing and sealing
- Finished goods warehouse
Routes above describe the principal control stages rather than a fixed step list. Product-specific operations, including enclosure assembly and thermal-component installation, apply only to the form factors that require them.
Testing & Verification
Verification is carried out at two levels. Production verification confirms manufacturing and functional requirements before product release. Platform qualification evaluates a configuration against a defined target system according to project requirements.
Production Verification — DRAM
These checks are performed before product release, as specified in the approved production process.
Production Verification — Storage
These checks are performed before product release, as specified in the approved production process.
Platform Qualification
Compatibility is evaluated against the target platform configuration, including initialization behavior, operating point and the conditions defined for the project. Qualification scope is defined per project and is not performed on every shipped unit.
Performance & Stability Verification
Performance and stability verification is defined according to product type, target workload and project requirements. Temperature-related verification is performed according to the applicable product specification and defined test scope.
Test categories describe verification objectives. The applicable scope, conditions and acceptance criteria for a project are defined in the corresponding test documentation.
Technical Evaluation & Support
Provide the target platform, required product configuration, operating conditions and qualification requirements. SIMORCHIP engineering will review the applicable verification and technical-support scope.
