DESIGN FOR MANUFACTURE & ASSEMBLY (DFMA)
Course Introduction
Design for manufacturability (also known as design for manufacturing & assembly (DFM/DFA) is the application of process, methodology and art of creating cost effective product designs. The design stage is important and ultimately influential in the end-product cost, quality, and time to market. Overall product lifecycle characteristics are committed at design stage. The product design is not just based on good design or engineering factors but it should consider the through-put or ease of manufacturing as well.
