Design for manufacturing of a wide range temperature probe

Abstract

This thesis covers the application of design for manufacturing (DfM) methods to the product development of a wide range temperature measurement probe to achieve high yields. Data analysis of a product of similar function and structure, using statistical process control, was used as a starting point for the new product. All manufacturing stages are evaluated, and the identified manufacturability challenges are discussed for improvements. This was done with experts in-house as well as from suppliers for the best results. Requirements from the intended application area also caused changes to the product structure. Impact of reusing existing parts and infrastructure in time and money are discussed. Additional challenges were caused by having to compromise the design because of a short time frame, limited volume and economical feasibility. The implementation is then veryfied and further improvements are made, based on the findings after the product has been moved to manufacturing. As many ideas are based on assumptions, there are benefits of continuous development of product or manufacturing infrastructure.
