What is pvt testing

Unless we decide to market the PU parts, or 3D printing for economic or marketing reasons. The product must be designed in small quantities and subjected to different stresses in order to test strength, tightness, safety… A large battery of tests will be required to determine whether the product is ready for production or not. DVT products are used for all laboratory validations Aging, Thermal and climatic cycle, vibration, packaging, waste, chemical resistance, biocomp… It is also at this stage that certification issues are integrated.

During the DVT phase, products should only use parts from medium production runs. And not parts via Dupli Silicone. To produce prototypes with full functionalities, with components intended for mass production, that can be used for certification CE and identify potential problems that need to be solved before design. Verify mass production yields Based on the one configuration of the final design for each shipping SKU. Generally between 30 and specimens, depending on the volume in MP mass-production and the cost of a prototype.

Certification requires a certain number of specimen and validation consumes at least 20 to 30 prototypes by itself. Not to mention those necessary for marketing. PVT is the last phase of industrialization, the final step before mass production that allows the first products to be sent to customers, often the backers of crowdfunding platforms.

During this PVT phase, the design is frozen and the assembly process is validated. The parts are close to the series but assembled by hand. The assembly line assembly is simulated to test the assembly process.

It is therefore at this stage that the assembler executes the planned production line s using all final equipment, processes and quality assurance steps. During the PVT phase, DFX s are corrected, test benches and mass production moulds are designed and ideally small mechanical adjustments are made.

It is very common at this stage to find assembly problems, and this may include design changes to plastics and PCBAs to minimize performance waste, optimize assembly if the cost impact is significant or optimize some parts if the FMECA reveals weaknesses…. All components and processes must be at the planned mass production stage, including packaging, logistics, freight forwarding and quality assurance controls. The production line must be optimized for the product, reducing the time between each step if possible, and making the entire process as smooth and reliable as possible.

To verify mass production yields at mass production rates. E lectronics and final components. Mechanical parts from production moulds.

Delivrable : final product in limited quantity. All these major steps have been simplified to make this article digestible. Whatever happens, making a product is a great adventure and a long journey. Having an overview of the different steps, even if it is quick, can help you avoid problems.

POC : Proof of concept. Prototype to prove the feasability of a concept. Before the product cycle development, the functional prototype.

PRD : Product requirement document. A PRD provides details about product to allow development team to understand capacities, fonctionnalites and characteristics of the product, required the reach the identified market needs.

Internet searches do not return satisfying results, so early hardware companies have this question a lot. The Proto build is a small test run of key product concepts to gain confidence that they can work — potentially a combination of different form factors including looks-like and works-like.

Purpose: to understand risks around specific modules or designs, usually with multiple variants in low quantities, such as:. Exit Criteria: one design concept for the product that the team has reasonable confidence is three major iterations or less from a mass-production worthy design. The EVT build is the first time you combine looks-like and works-like into one form factor, with production intent materials and manufacturing processes.

Exit Criteria: one production-worthy configuration that meets all of the product requirements for functionality, performance, and reliability. The DVT build is supposed to be one configuration of your production-worthy design, made of components from production processes and hard tools and on a line following production procedures. I believe very few companies actually stick to this requirement — because even if miraculously there are no outstanding issues, there may be parallel efforts to cut cost or increase yields that create additional configurations to build.
