Abstract In this article, the processing of molded interconnect devices (MIDs) was studied via in-mold decoration (IMD) molding technology. A screen printing process using carbon black and printing ink was proposed in the study. For comparison, various conductivity materials such as copper powder, iron powder, carbon black and silver composite were studied with the screen printing method. The results show that there is no electrical conductivity for the ink containing copper or iron powder up to 90% concentration. The low cost carbon black with printing ink was shown to be successful for the IMD process.

PZT(70/30) powder was prepared by a sol-gel method and PZT thick films were fabricated by the screen-printing method on the alumina substrates. The coating and drying procedure was repeated 4 times. And then the PZT(30/70) precusor solution was spin-coated on the PZT thick films. A concentration of a coating solution was 0.5 mol/L and the number of coating was varied from 0 to 6. The porosity decreased and the grain size increased with increasing the number of coatings. The thickness of the PZT-6(6: number of coatings) films was about 60~65μm. All PZT thick films showed the typical XRD patterns of a typical perovskite polycrystalline structure. The relative dielectric constant of the PZT-6 thick film was 540. The remanent polarization and coercive field of the PZT-6 film were 23.6 μC /cm2, 12.0 kV/cm, respectively.
