Meaning
The procurement of pre-certified wireless or sensor modules that have been modified by the vendor to meet specific customer requirements offers a middle ground between off-the-shelf parts and fully custom designs. Utilizing semi custom module sourcing allows hardware designers to secure unique features like a custom firmware stack or an integrated antenna without the high cost of a full hardware design. This approach leverages the vendor’s existing regulatory certifications to speed up time to market.
The customization is bounded by the hardware layout of the base module.
Vendor Modification
Firmware changes or minor component swaps are executed by the module vendor under their own quality system. This ensures that the base functionality and reliability of the module remain intact. The modified module is then delivered as a unique part number to the buyer.
Certification Strategy
Regulatory certifications can often be maintained through a permissive change process if the hardware modifications do not affect the radio parameters. This avoids the need for a full, expensive testing campaign at an accredited laboratory. The vendor provides the necessary documentation to demonstrate that the changes do not exceed the limits of the original certification.
This accelerates the launch of the product.
Supply Continuity
Sourcing from an established vendor reduces the risk of supply chain disruptions. The vendor handles the procurement of the base components and maintains the production line. This ensures a steady supply of customized modules for the buyer.
