Meaning
Project checkpoints associated with custom hardware development represent the formal completion of specific design or tooling phases where non-recurring engineering costs are invoiced. Achieving an NRE milestone triggers pre-negotiated payments and authorizes the transition from layout to prototype manufacturing. These gates ensure that both the module supplier and the purchasing company agree on the mechanical and electrical specifications before expensive tooling is made.
Tooling Release
Production of injection molds or custom photolithographic masks begins only after the design files receive formal sign-off. If a design modification occurs after this NRE milestone has been passed, the buyer must pay additional fees to remake the tooling. This structure protects the supplier from absorbing the costs of late requirement changes.
Prototype Validation
Early functional testing of the custom antenna module provides the hardware evidence needed to clear the next stage of development.
Verification Gate
Each development stage demands specific documentation and test results to prove that the device meets its targeted performance criteria. Reviewing the initial RF performance data on a small batch of boards serves to validate the design files. When the testing results match the simulation models, the engineering teams sign the release form to activate the subsequent project phase.
