Establish best practices for hybridization and injection moulding of rigid control units on in-mould flexible devices, in the case of study, an in-mould battery-free geolocation tag, a FR4-based control unit which has the function of enabling energy harvesting and communication of dedicated printed antennas, is directly hybridised on a flexible substrate which is ultimately integrated in a plastic part through injection moulding.
This document aims to develop the processing of hybridization of rigid control unit on printed functional foils and the subsequent incorporation into plastic pieces, The specific objectives are:
1) Design and assembly of components by Pick & Place of the rigid control unit.
2) Integration into a plastic piece through injection moulding.
Procedures for the accurate attachment, alignment of the control unit on substrate with the injection mould and for reliable plastic over-moulding process are defined.
