The production of flexible circuit boards was introduced after technologic experiments that had been finished at the end of 2002. In the first step we spezialized on the single sided flex PCB. In the 360.000 EUR investment that we did by the end of 2002 we already took the technologies needed for the production of flexible PCBs into consideration. From the beginning of 2003 we have started the manufacturing of double sided flex PCB using polyimid base material. By the middle of 2004 all process development relating to the production of flexible multilayer and rigid-flexible combination PCBs will be completed. The introduction of flexible PCBs using different types of metal conductor material is also planned for the end of this year.
