System Boundary

Defining the system boundary is crucial for ensuring a fair and accurate comparison. Including raw materials, their production processes, the FPCB production processes, and wastewater treatment for chemical etching within the boundaries ensures that the assessment captures the core environmental impacts. However, it can also be interesting to just compare the production processes without the material impact.

The two processes compared are the DPP process and the industry-standard chemical wet etching process for manufacturing FPCBs. For the DPP process, environmental impacts are calculated for both aluminum and copper coatings. For the chemical etching process, impacts are calculated only for copper, as it is the current industry standard. The study focuses on comparing these two processes for producing an identical product, so only the differing steps in each process chain are analyzed to accurately identify their differences.
