- Considerations of cost, high speed, high reliability, high manufacturability and environmental compatibility have to be taken into account in future product development of electronic products. To simulate the environmental compatibility, for example a Life Cycle Assessment (LCA) can be performed. An electronic product usually consists of hundreds to thousands of electronic and mechanical components. To perform an LCA is very time consuming if a Life Cycle Inventory (LCI) is done for every single component. This is not needed because the unit processes in the upstream product system in some cases are the same for the ingoing components. In this paper a generic model for LCI is developed and applied to one product system (a business telephone). In this model, the components are divided into main groups and then into sub-groups that result in process modules for unit processes that are similar for the ingoing components. There already exist some models that describe the LCI of electronic products in other ways. This model takes the LCI strategy for the manufacturing phase one step further by identifying which processes constitute part of the common denominator of the upstream product system and proposes which ones should be inventoried first. The developed model makes it possible to obtain a higher resolution and level of understanding compared to earlier models with respect to both components and processes.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- We have studied the electron transmission of an electrically conductive adhesive (ECA) composed of micro-size and nano-size metal fillers. By quantum mechanics, it has been shown that due to the quantization of electron states in the nano particle, energy barriers are formed at interconnects between the microfillers and nano particles. The energy barriers effectively reduce the electron transmission through the nano particles. For an ECA consisting of 50-nm-diameter nano particles, the electron conduction is reduced by a factor of 2, and the time for the electron to transmit through the nano particle is about 100 ps.
