Abstract

Electronic assembling is strongly automated. In 1980 the use of SMD technology for electronic assembly began on a mass scale. This technology is currently used in more than 90% of the cases. It requires a precise passing of SMD components so that it can assemble with high speed and precision. The technology is hardly applicable for non-standard component such as contact components. In the production of flame detectors by the firm of “UniPOS” non-standard contact components are used. These components have to be positioned and soldered precisely because after that there will be no opportunity for automated assembling of the final products. At first these components were put by hand and they were soldered by SMD technology. This led to a lot of labor expense, a low quality and a lot of rework, which made the products more expensive. By a vibration and a specially created strip for leading and positioning the contact elements conditions for automated SMD assembly were created. This enabled a large decrease in the prime cost of the products and an increase in the productivity of the whole production.
