The success of New Product Introduction (NPI) is critical for original equipment manufacturers (OEMs) striving to remain competitive in today’s market. NPI encompasses the journey from an innovative concept to a fully functional electronic product, involving intricate processes like design, prototyping, manufacturing, assembly, testing, and inspection. However, even with substantial investments in resources, time, and effort, many NPI projects encounter unexpected pitfalls. This article discusses the key factors that determine the success or failure of NPIs and offers tips for optimizing the process.
Understanding the High Stakes of NPI
Introducing a new product is no small feat. Studies indicate that an NPI can take up to 24 months to complete, requiring OEMs to invest nearly 25% of their resources in the project. Despite these efforts, some NPIs fail, often due to a lack of preparation, inadequate checks, or hasty decisions. So, what sets successful NPIs apart from those that fall short? Here are some critical factors that OEMs must focus on to ensure their NPI’s success.
1. Design for Assembly (DFA) and Design for Manufacturing (DFM) Checks
The journey of NPI begins with translating a concept into detailed design files, including schematics, Gerber files, NC drill files, Bill of Materials (BOM), assembly instructions, and CAD drawings. At this stage, two essential checks need to be conducted:
- DFA (Design for Assembly) Check: Performed by design engineers, this check focuses on simplifying the product assembly process. It ensures that components are easily accessible, align correctly, and fit seamlessly into the overall design.
- DFM (Design for Manufacturing) Check: Carried out by manufacturing engineers, this check assesses the design’s feasibility for large-scale production. It examines aspects like materials, layer counts, copper weights, and spacing to ensure efficient manufacturing.
Conducting these checks early in the process can identify potential design issues, enhance product viability, reduce costs, and accelerate time-to-market.
2. Selecting the Right Assembly Type
The assembly process is a crucial phase in NPI, and OEMs typically have three options to choose from when partnering with contract manufacturers:
- Kitted Assembly: The client provides all components, including electronic parts, bare circuit boards, and design files. Quality assurance becomes the client’s responsibility in this case, as the manufacturer only handles assembly.
- Partial Turnkey Assembly: Both the client and the manufacturer collaborate. The client supplies critical and expensive parts, such as ICs, LEDs, and connectors, while the manufacturer sources the more affordable components. This arrangement allows for shared responsibility in component quality.
- Full Turnkey Assembly: The manufacturer takes charge of sourcing all components based on the design files provided by the client. This option reduces client involvement, but it emphasizes the need for a reliable manufacturer who can ensure quality sourcing.
Regardless of the assembly type chosen, it’s vital to check the availability and quality of components through thorough inspection and testing.
3. Manufacturing and Assembly Steps
The manufacturing process is complex and consists of various steps that directly influence the performance and reliability of the final electronic product. Some of the critical manufacturing steps include:
- Layer Count: The number of layers in the PCB, influencing its complexity and performance.
- Copper Weight: Affects the PCB’s current-carrying capacity and durability.
- Substrate Material: Determines the PCB’s mechanical and thermal properties.
- Minimum Tracing/Spacing: Ensures proper signal transmission and minimizes interference.
- Solder Mask: Protects the copper traces and prevents solder bridging.
- Surface Finish: Impacts solderability and component placement.
Similarly, during the assembly phase, attention must be paid to the following:
- Surface Mount and Through-Hole Assembly: The accuracy and precision in placing components.
- Component Packages: The compatibility of different component packages with the PCB layout.
- Quality Grade: The overall reliability of the assembly, especially for mission-critical applications.
4. Testing and Inspection for Quality Assurance
Comprehensive testing and inspection are fundamental to ensuring the quality of the final product. Here’s how quality is assured:
- Bare PCB Testing: Techniques like electrical testing, flying probe testing, and bed-of-nail testing are used to verify the functionality of the bare PCB.
- Assembly Testing: Advanced inspection methods, such as Automated X-ray Inspection (AXI) and Automated Optical Inspection (AOI), help detect potential issues like solder defects, misaligned components, and faulty connections.
These testing phases help identify errors early, reduce costly rework, and ensure that only fully functional products proceed to the market.
