Design for Automation


Design for Automation
It is said that 75% – 90% of manufacturing costs for an electronic product are determined at the design stage. You have, therefore decided to adopt a design for automation (DFA) philosophy for the mass production of your electronic product. Initially you have decided to research the following parameters:

? Part Compliance
? Modularity
? Standard Tooling
? PCB issues regarding insertion/onsertion and component fixing
? SMD issues
? Assembly methods
? Interconnection
? Solderabilty and soldering methods for differing component types

Following your investigation you intend to apply relevant techniques to the manufacture of your product.

Guidance notes

Remember you do not necessarily have to solve the problem described. You do, however, need to understand and be able to explain how you would approach the problem.

Learning Outcomes

Following this PBL cycle you should be able to:

? Explain why electronic design should take into account the manufacturing process.
? Discuss the concepts of part compliance, modularity and standard tooling.
? Discuss relevant PCB issues with regard to component type and automated assembly
? Choose appropriate interconnection methods
? Choose appropriate assembly methods and soldering techniques for use with differing component types.
? Justify the above choices.
