NPI-Plus Upgrades Reporting and Testing Strategies

Reading time ( words)

NPI-Plus, Universal Electronics' quick-turn PCBA prototype and NPI organization, has found that a thorough approach to manufacturing design and supply chain reviews along with careful testing can mean fewer headaches for design engineers.

The NPI-Plus team will deliver product within days and the project engagement process begins with a thorough summary report that is broken down into four sections:

  • Design for Manufacturability (DFM) will verify that your PCB design meets over 300 design rule checks as well as verifying the manufacturability of the entire project.
  • Design for Assembly (DFA) virtually places the components from your Bill of Material to ensure the parts do not violate an additional 300 checks.
  • Design for Test (DFT) analyzes the design to ensure the project be testable in full-scale production.
  • Bill of Materials (BOM) analysis using Arrow's SiliconExpert software checks the components for issues regarding Life Cycle, Availability, Substitute Data, Environmental, and more.

"We have made a significant investment in SiliconExpert's and Mentor Graphic’s ValorNPI software," said Kevin Grob, NPI manager. "And the rigor we’ve built into our process helps ensure a smooth transition from PCB design to fabrication, assembly and test. More scrutiny upfront means fewer headaches along the way, and a high quality end product."

A careful BOM analysis that takes an in-depth look into electronic component lifecycle statuses, multi-sourcing, available inventory, and environmental compliance data helps guide component selection so there is less concern for rework later. And form-fit-function cross references can mean less chance for costly redesigns and provide multi-sourcing options that help engineers make the best design decisions. "SiliconExpert software also helps ensure compliance by identifying non-compliant components with data for environmental and governmental legislations," explains Grob.

Unique to NPI-Plus' service is a rigorous battery of tests that accompany every build. These include Automated Optical Inspection (AOI), X-Ray, Manual Inspection, and Flying Probe – which tests various nodes throughout the board to ensure the components work properly throughout the board. "We do not sacrifice quality at any step in our process. If we turn a project quickly but it’s not done right, we haven’t provided the reliable end result our customers have come to expect. NPI-Plus ensures the quality of your boards by performing multiple tests throughout the build," said Grob.

The rigor of the process does not, however, compromise NPI-Plus’ ability to satisfy the need for speed. From Alpha Build Quick Turns that are full turnkey and ship within days, to ramp-to-production builds that mirror exactly a customer’s active lifecycle boards and ship within two to four weeks. "We have built key relationships with high-tech PCB suppliers to ensure rapid builds, and we have all of the necessary resources to turn assemblies as fast as you need them," said Grob.
