Adhesion incompatible polymer-polymer composites with increased media tightness by sintered microstructures
For protection of electronic components against environmental influences, an innovative surface structuring process based on a sintered powder layer was investigated. The applied treatment pro-cess leads to micro undercuts on the insert surface, which can result in an increased bond quality and reduced leakage rates because of labyrinth sealing effects. With this new method, entire assemblies or specific components can be protected by manufacturing in assembly injection molding, which would enable the use of an efficient and mass production suitable process for assembly protection. The results clearly show that an increased pull out force level in combination with a reduced leakage rate can be achieved by means of micro structuring with a sintered powder layer.
The Journal of Plastics Technology is a peer reviewed internet periodical published under the auspices of the Scientific Alliance of Polymer Technology (WAK)
International Polymer Processing, the journal of the Polymer Processing Society, is a discussion forum for the world-wide community of engineers and scientists in the field of polymer processing.
The journal covers research and industrial application in the very specific areas of designing polymer products, processes, processing machinery and equipment.
The Journal of Plastics Technology is indexed in SCOPUS, the largest abstract and citation database of peer-reviewed literature.
