Efforts to enhance the productivity, to be in accordance with environmental regulations, to assure performance, quality and reliability in competitive market, are the major trends to any company of the industrial sector. This is particularly critical in the automotive market due to safety requirements and product conformity, but it is not enough to ensure success. The key to accomplish that is presented in this work through an investigation of innovation plans and technological strategy developed and applied to an electrical electronic architecture company. The results show the role of this approach prioritizing the corporative investment and goals, increasing profits by adding value to sale, analyzing collaboration between private companies and universities, revealing opportunities to apply for Government Innovation Program financial support. All these factors have been applied to the modernization of electrical automotive architecture for Brazilian emergent market.

Miniaturization is an important trend in many technology segments, once it can enable innovative applications generating new markets. This trend was begun in electronics industry after World War II and has spawned changes into automotive sector also. For Automotive Wiring Harness, miniaturization is clearly presented in most of the components, mainly because of its benefits like the potential of mass reduction, cost reduction and efficiency improvement. Furthermore the main voice of customer points to cable gauge reduction that represents a considerable challenge for connection manufacturing process due to quality control limitations presented by conventional crimp process for 0,35 [mm₂] cables and smaller. According to that, the scope of this article is to present, in details, a manufacturing process optimization for an alternative and more robust technology of joining copper stranded cables to tin brass terminals used on automotive wiring harness, Resistance Welding.
