Environmental and technical characteristics of conductive adhesives versus soldering

Abstract
The electronics and electrical industries are facing increasing pressure from legislation to remove lead from its products.  This is because of the hazards to health during manufacture of the materials and environmental damage caused by their end of life disposal. For producers using/producing solder systems, electronic components and printed circuit boards, this legislation is likely to result in a range of changes in their production/assembly systems.  This report describes the environmental aspects of introducing conductive adhesives in electronics manufacture compared with solder.  It also contains a technical assessment of 13 adhesive variants by means of laboratory surveys and industrial cases

Abstract in Danish
Elektronikindustrien står over for stigende lovgivningskrav om at fjerne bly fra deres produkter. Dette skyldes dels den sundhedsmæssige risiko forbundet med fremstillingen dels den miljømæssige skadevirkning forårsaget ved deponeringen af elektronikskrot. Lovgivningen vil forudsætte en række ændringer af produktions- og montagesystemerne for producenter som bruger eller producerer loddematerialer, elektronikkomponenter og printkort. Denne rapport beskriver de miljømæssige aspekter omkring indførelsen af ledende lime i elektronikproduktionen sammenlignet med lodning. Rapporten indeholder også en teknisk vurdering af 13 forskellige limvarianter testet i laboratoriet og i form af industrielle cases.
