Rapid prototyping is a broader concept that includes 3D printing among other techniques like CNC machining and injection molding for creating prototypes quickly.
Tracing a PCB circuit involves carefully examining and mapping out the connections and components on a board to understand its electrical flow and functionality.
PCB reverse engineering is the process of analyzing a physical PCB to recreate its design. Preventing it involves using encryption, proprietary components, and complex circuit designs.
Materials used for fixture design include metals (aluminum, steel), plastics (ABS, Delrin), and composites, chosen for their durability, resistance, and application-specific properties.
The three types of FMEA are Design FMEA (DFMEA), which focuses on potential failures in product design; Process FMEA (PFMEA), which identifies potential failures in manufacturing processes; and System FMEA (SFMEA), which analyzes failures at the system or subsystem level.
PFMEA, or Process Failure Mode and Effects Analysis, is a structured approach to identify, prioritize, and mitigate risks in a manufacturing process, aiming to improve quality and reliability by preventing process-related failures.
DFM (Design for Manufacturability) is a subset of DFX (Design for Excellence), focusing specifically on designing products in a way that simplifies manufacturing processes, reduces costs, and ensures quality. DFX encompasses a broader range of considerations, including manufacturability, assembly, testing, cost, and sustainability, aiming for overall excellence in product design and production.
Analyzing a PCB involves using EDA software to simulate electrical functionality, signal integrity, thermal management, and mechanical stability, identifying potential issues before manufacturing.
Manufacturability Assembly efficiency Material choice Compliance with standards
Design for Assembly (DFA) focuses on simplifying a product's assembly to reduce costs and time. Example: Using snap-fit components in a toy to minimize the use of screws and tools.
