Manufacturing process selection

The manufacturing process selection strategy is given below, but points 4, 5 and 6 apply to all selection strategies  

4 Consider each PRIMA against the engineering and economic requirements such as  

5 Consider the economic positioning of the process and obtain component cost estimates for alternatives. 

6 Review the selected manufacturing process against business requirements.

To determine the constants A and B in Eq. 19.12, a fabricator will need to characterize their manufacturing process. Selecting a number of printed circuits currently being produced that have various complexity indexes does this, ideally some low, medium, and high. The first-pass yield (at electrical test without repair) of these printed circuits for several production runs is recorded. Any statistical software program that has a model-based regression analysis can now determine A and B from the model (Eq. 19.13). 

The rate of grid corrosion is influenced by the composition of the grid alloy and the manufacturing process. Selection of appropriate alloying additives is important to reach the desired service fife. 

The primary objective of the text is to provide support for manufacturing process selection in terms of technological feasibility, quality of conformance and manufacturing cost. The satisfaction of this objective is through ... 

Quantity - Production quantity per annum, and consequently the number of joints to be produced, accounts for the economic feasibility of the joining process. The quantities specified for selection purposes are the same as for the manufacturing process selection strategy. 

In a business concerned with product design and manufacture, why is it worth giving consideration to manufacturing process selection in the early stages of the design process ...
