Engineering Verification

What is Engineering Verification

During the product development phase, product verification testing procedures are essential to provide testing and analysis results. First, building an engineering prototype is essential.

It is a series of components created by combining engineering and design to represent the final product. Typically built using rapid prototyping, this robust and highly accurate pre-production prototype undergoes rigorous testing and evaluation to validate product design, engineering, and manufacturability.

Prototype engineering focused on optimizing mass production

Engineering prototyping and testing help uncover problems as product development moves into subsequent stages where design and engineering meet. Identify improvements and iterations before investing in expensive tools and putting them into production, making future production processes as smooth and reliable as possible.

Through a series of verification test processes, including basic functional testing, manufacturing process, performance parameter measurement and verification of certification standards, it can be verified that the design meets the expected product specifications and performance. The goal is to verify that the design has been correctly implemented into production.

Tested in 3 different engineering validation phases

Validation is a progressively rigorous process that combines design and engineering development with prototyping and manufacturing, designed to provide objective, comprehensive testing to meet a product's intended design requirements, performance, specifications, and standards, and to ensure sustained large-scale Production.

Engineering Verification Test

Verify that the product meets the design specification functional requirements. EVT versions originate from CNC machining, vacuum casting or rapid machining.

Quantities range from 20-50 pieces; material and mechanical properties of parts must meet inspection requirements; tighter tolerances are required to verify functionality in assembly and in use.

Basic performance testing, including power, thermal, and EMI; identify design or process flaws; identify design or process improvement options; perform second verification after changes

Design Verification Test

Design Verification is an intensive series of testing procedures used to verify that a product complies with specifications, industry standards and certifications. It also improves tools and processes for consistent production runs while using pre-production components for ideal testing requirements

Ensuring production processes meet chemical and environmental requirements; extensive reliability and compliance testing, including flame retardant, drop, waterproof, battery safety, and more;

Verify product certifications and standards in different countries or regions, such as RoHS, CE, FCC, UL, etc.; require quick failure analysis and corrective actions; optimize production schedules.

Production Verification Test

It is the first trial production to identify defects and evaluate optimizations at each line stage. The entire production line is tested to ensure quality.

>Product quantities often exceed 500 pieces, perfect for sale; no tool changes to get started.Batch production validation (yield, time, target cost, rework time, etc.); Design for Assembly (DFA) validation to optimize the assembly process and reduce time and cost.

Development and testing of Quality Assurance (QA) and Quality Control (QC) procedures; Standard Operating Procedure (SOP) development and staff training procedures.
