We begin by evaluating the product’s design files, BOM (Bill of Materials), functional specifications, and assembly constraints. Our engineering team performs DFM (Design for Manufacturability), DFA (Design for Assembly), and DFT (Design for Testability) reviews to identify improvements that reduce complexity, prevent production issues, and enhance long-term dependability. This step often includes component optimization, alternate sourcing suggestions, layout refinement, and mechanical alignment checks.

Prototype builds are executed in controlled batches to test the assembly flow, material compatibility, process stability, and hardware-software interaction. Based on this data, we refine documentation, assembly instructions, test fixtures, and inspection checkpoints. This ensures the product performs consistently in both small runs and high-volume manufacturing environments.

Our NPI process includes:

·        BOM verification and sourcing strategy

·        Prototype assembly and build iterations

·        Test development and validation procedures

·        Process flow optimization and work instruction creation

·        Quality inspection planning and traceability setup

·        Pilot production ramp-up and readiness evaluation

The outcome is a fully validated product with predictable performance, reliable assembly processes, and controlled production cost. Whether launching a new IoT device, industrial controller, consumer electronic unit, or custom embedded system, HJ Technologies ensures an efficient and confident transition into mass manufacturing.
