The Old Days Before DFM, the motto was "I designed it; you build it!“ Designs were then thrown over the wall leaving manufacturing people with the dilemma of either objecting (but its to late to change the design!) or struggling to launch a product that was not designed for manufacturability.

Design for Manufacturability Design for manufacturability is the process of proactively designing products to optimize all the manufacturing functions: fabrication, assembly, test, procurement, shipping, delivery, service, and repair, and

Design for Manufacturability Assures: the best cost, quality, reliability, regulatory compliance, safety, time-to-market, and customer satisfaction.

Design for Manufacturability Companies that have applied DFM have realized substantial benefits. Costs and time-to-market are often cut in half with significant improvements in product line breadth, delivery, customer acceptance, in general, competitive posture, quality, reliability and, serviceability.

DFM Guideline P 4) If part symmetry is not possible, make parts very asymmetrical. DFM Guideline P 7) Make part differences very obvious for different parts. Anderson’s law: “Never design a part you can buy out of a catalog”

You should Consider Simplify the design and reduce the number of parts Standardize and use common parts and materials Design for ease of fabrication (Mechanical Parts) Design for ease of assembly (Mechanical and Electronics) Avoid unnecessarily tight tolerances that are beyond the natural capability of the manufacturing processes Mistake-proof product design and assembly (poka -yoke) so that the assembly process is

You should Consider Design for efficient joining and fastening (Easy assembly and disassembly) Design modular products Design for automated production Design printed circuit boards for assembly Design for testability
