"Injection Moulding of flexible devices"

Abstract

The demand for low-cost, randomly shaped and lightweight electronic devices has increased significantly over the past years. Hereby one path is to employ the Injection Molded Structural Electronics (IMSE) process where electronic films are overmolded with a thermoplastic to form the final part. Those films can comprise surface mounted components, LEDs, capacitive sensors or flexible Printed Circuit Boards (flexPCBs) which are embedded between plastics sheets via lamination processes. Hence devices such as personal activity meters or (car) control panels with smooth surfaces can be produced that bypass the need of additional buttons and sliders. Elevated temperatures and shear stresses prevail during overmolding which can result in damaged parts after this final manufacturing step. Hence various factors such as the individual film(-layer) materials and injection molding parameters have to be considered carefully to ensure damage free manufacturing. The aim of this work was to investigate those aspects in principal by overmolding test film strips and to assess their visual integrity afterwards. These specimens consisted of a flexPCB encapsulated by two different thermoplastic polyurethanes (TPUs) as glue middle layer and polycarbonate (PC) or Polyethylene terephthalate (PET) sheets as outer layers. Injection molding parameter studies were performed where the films were inserted into a stepped plate mold and overmolded with PC using different melt temperatures, mold temperatures and injection speeds. The distortion on the films was found to be reduced with higher melt temperature, lower mold temperature and faster injection speed. At given molding settings films made of materials with the higher melting temperature performed better. Additional geometric conditions such as proximity to the gate and low mold thickness were found to affect the integrity of the produced films negatively.
