Connections between two subassemblies.

For example, a rack or frame may hold

several shelves of subassemblies that

must be connected together to make up a

complete system.

Connections between PWBs, including

PWB-to-PWB interconnections or card-to-

motherboard interconnections.

Printed wiring board (PWB) level of

interconnections. Printed conductor paths

connect the device leads of components

to PWBs and to the electrical edge

connectors for off-the-board

interconnection.

Packaging of silicon chips into dual-in-line

packages (DIPs), small outline integrated

circuit (SOICs), chip carriers, multichip

packages, and so on, and the chip-level

interconnects that join the chip to the lead

CO2 Footprint

System Hierarchy in Printed Electronics 33

1. Use Phase

As there is no long use phase for „disposable“ smart packaging the CO2

impact depends on the manufacturing phase.

2. Manufacturing phase

The drying / sintering processes are the main driver for level 1. This needs to

be optimized !

3. Printed Electronics

Moving into a clean room environment for production would significantly

decrease the CO2 benefits of PET vs. SMT

4. Organic Electronics

What would have changed if we had used organic material ?
