Eashub offers customers fast, affordable prototype assembly services, including PCB manufacturing, components sourcing, and PCB assembly. Primarily, Eashub can deliver a complete turnkey PCBA in less than four weeks, provide DFM advice, systematically document customer’s product information, and prepare for a smooth transition to the next build.
PCB Assembly Prototype is one of the most critical steps from concept to reality products; Eashub supports product stages from conception, EVT, DVT, PVT, and MP on PCBA prototype. EVT DVT PVTMP acronyms describe the principal and classic steps before product design lockdown. These phases of prototype development exist to eliminate defects, design flaws, software bugs, and risks before entering the volume production period. Identifying, analyzing, handling, and fixing these flaws during the engineering design phase is critical. Otherwise, any activity on producing or selling producing and selling defective products will bring trouble and cost more.
EVT (Engineering Verification Test)
EVT stage comes after the first concept design is verified theoretically. The EVT phase will usually take a few small-batch runs on prototypes of various primary functions or sub-systems. EVT is mainly a new design. The direct purposes are to build or work out prototypes to define and validate the product’s core functionality. EVT prototypes can be anything between a simple electronics circuit prototype, PCB Assembly, and functional prototype with a box enclosure. EVT is rolling design change with times iterations between theoretical design and the most feasible design; in this stage, the bottom line is systematical flaws or functional bugs can be fixed by engineers and ready for the validation in the next step. Prototypes delivered throughout the EVT stage may look somewhat ragged, even not tidy. And some assistant or mature modules are missed.
DVT (Design Verification Test)
DVT stage is more like a system development cycle with software and hardware. And DFM also is implemented at this phase. All things are developing toward an actual product. The assistant systems or modules will be assembled and validated together. The product will have a cover or enclosure that looks like an on-sale product. The majority of design work targets for volume production will be locked down. It is a pretty important stage connecting future commercial sales requirements and product specifications. The project team must ensure the design complies with the target markets’ standards and passes the certification. Verification typically includes CE, EC, FCC, UL, RoHS, REACH, CCC, etc.; it is variant among regions generally. Product teams will review critical features, yield ratio, BOM cost, and volume at this stage. The optimization plan for the next step is also listed down. The DVT prototypes and documentation are nearly final locked down. No core functional features can be revised.
PVT (Product Verification Test)
PVT is the last stage before commercial mass volume production. Although the PVT is not a hard time for development, the results will have a critical effect on quality, product cost, and volume deal. Only slight engineer changes are allowed at PVT; The stage is almost like a test for future volume production. At this stage. Mass production yield ratio will be monitored, design flaws will be cleaned, and hardware and software systems will be managed routinely. Golden samples may directly ship to end customers. At this stage, some optimizing proposals during EVT will be evaluated, like alternative source change, fixture adjustment, or a new testing tool developed. The gating factor of this stage is Tooling preparation, which usually takes a few months to copy.
MP is mainly like the status of the milestone rather than a cycle time on engineer development. MP usually means all designs are lockdown, the product go-to routine management process, and the business focus will transfer from the development team to the supply chain team. They take the lead in on-demand planning management, and a regular PO and forecast model will run on track—the factory team is in charge of the whole manifesting process without more development engineers’ support.
