Our customers deliver products that perform under the most demanding conditions including in harsh environments, operating rooms, and outer space. The success of these circuits depends on the quality of the manufacturing and Naprotek's engineering services ensure process repeatability and high production yield. We offer a variety of design services to reduce manufacturing time and development costs including:
- Design for manufacturability (DFM) and design for test (DFT)
- RF/microwave component design
- Thin film processing, wafer dicing, ion beam milling, and semiconductor package design
- PCB design, layout, and custom engineering.
- Advanced engineering in fiber optics, silicon photonics, multi-chip modules (MCM) and micro-electro-mechanical systems (MEMS).
Test & Inspection
Advanced Testing from Benchtop to Volume Production
Naprotek engages with manufacturers at various points in design and development, ranging from early prototype to full production. Our in-house engineering teams work closely with new programs to ensure they have the necessary test and inspection support to meet our quality and reliability standards. We offer a full range of test services including:
- Flying probe and in-circuit test (ICT)
- Solder paste inspection (SPI), automated optical inspection (AOI), and multi-dimension X-ray imaging
- Microscopic inspection
- First article inspection (FAI)
- Functional test
For over 15 years, we have been producing automated test equipment (ATE) boards for leading semiconductor companies. These designs have upwards of 40-to-60-layer boards with unique thermal profiling, specialized circuits, stiffeners, and other ancillary requirements. Other turnkey electrical and quality services include RF/microwave performance (MIL-PRF) testing and high-reliability MIL-STD screening.
Rapid Prototyping
Maintaining Manufacturing Velocity
We help our customers get their products to market faster by transforming their concepts into manufacturable designs. Using established systems, we can deliver quick turn printed circuit boards in as little as one to five days. The key to Naprotek's efficiency is a combination of:
- Automated quoting and purchasing systems
- Experienced operations and program management teams
- Expedited material acquisition with minimal excess
- Consigned material support
Hybrid kits, including turnkey, consigned, and mixed components, reach purpose-built manufacturing cells to produce circuits with speed while allowing rapid change management. Production-ready test, inspection, and final quality control techniques ensure that both reliability and schedule are maintained. Rapid response manufacturing and engineering services means our customers can meet their schedule requirements, reduce development times, and move quickly into production.
New Product Introduction
Streamlining the Ramp to Production
Bringing a product to market requires a knowledgeable product launch management team with manufacturing readiness expertise. The success of Naprotek's new production introduction (NPI) strategy is led by dedicated program managers who ensure clear communication and decisive action. Naprotek supports a rapid ramp to production through:
- Quick turn prototyping
- Design for excellence activities
- Scalable test & inspection process development
- Supply chain & logistics design
Our dedicated team manages each product such that the final design transitions seamlessly into our manufacturing process with clear documentation, defined test procedures, and inspection readiness. We manage a proprietary process to expedite design validation at the front end of production through the various qualification steps to learn, improve and reduce cycle times for production.
Integration & Box Build
