  • System on Panel (SOP) can integrate many functions by Thin Film Transistor (TFT) circuits on an insulator substrate without using external driver LSIs. However, to make practical SOP has become more and more difficult because of rapid cost reduction of the driver LSIs. This paper will review the circuit design technology trend for SOP and introduce an example of a practical SOP, 2.0inch QVGA full color active matrix OLED with 8bit source driver.

  • In this paper, a miniaturized parallel coupled bandpass filter using multi-layered LTCC(Low Temperature Co-fired Ceramics) substrate for SOP(System-On-Package) is proposed for applications to wireless communication systems. The fabricated BPF is composed of five 106${\mu}{\textrm}{m}$ thick LTCC layers and its size is 5.24mm x 4.3mm x 0.53 mm. The measured characteristics of the BPF show the center frequency of 5.8GHz, bandwidth of 200MHz, insertion loss of 2.326dB and return loss of 13.679dB. In addition, the attenuation is 28.052dB at 4.7GHz.

  • In this research, damage behavior of singly oriented ply (SOP) fiber metal laminate (FML) subjected to concentrated load was studied. The static indentation tests were conducted to study fiber orientation effect on damage behavior of FML. During the static indentation tests, acoustic emission technique (AE) was adopted to study damage characteristics of FML. AE signals were obtained by using AE sensor with 150kHz resonance frequency and the signals were compared with indentation curves of FML. The damage process of SOP FML was divided by three parts, i.e., crack initiation, crack propagation, and penetration. The AE characteristics during crack initiation show that the micro crack is initiated at lower ply of the plate, then propagate along the thickness of the plate with creating tiber debonding. The crack grow along the fiber direction with occurring 60∼80dB AE signal. During the penetration, the fiber breakage was observed. As fiber orientation increases, talc fiber breakage occurs more frequently. The AE signal behaviors support these results. Cumulative AE counts could well predict crack initiation and crack propagation and AE amplitude were useful for the prediction of damage failure mode.

  • Tn this paper, PCB (Printed Circuit Board) embedded $BaTiO_3$ MIM capacitors were designed, fabricated, and characterized for low cost organic SOP applications by using 3-D EM simulator and low temperature processes. Size of electrodes and thickness of high dielectric films are optimized for improving the performance characteristics of the proposed embedded MIM capacitors at high frequency regime. The selected thicknesses of the $BaTiO_3$ film are $12{\mu}m$, $16{\mu}m$, and $20{\mu}m$. The fabricated MIM capacitor with dielectric constant of 30 and thickness of $12{\mu}m$ has capacitance density of $21.5p\;F/mm^2$ at 100MHz, maximum quality factor of 37.4 at 300 MHz, a quality factor of 30.9 at 1GHz, self resonant frequency of 5.4 GHz, respectively. The measured capacitances and quality factors are well matched with 3-D EM simulated ones. These embedded capacitors are promising for SOP based advanced electronic systems with various functionality, low cost, small size and volume.

  • Novel system-on-package (SOP) - D technology to improve the mechanical and thermal properties of a MCM-D substrate was suggested. Based on this investigation, the two types of band pass filters for the V-band application with unique structure were designed and implemented using 2-metals, 3-BCB layers. The first type using distributed resonator had the insertion loss below 2.6 dB at 55 GHz and group delay was below 0.06 ns. For the second type with edge coupled structure, the insertion loss and group delay were 3 dB and 0.1 ns, respectively. Suggested MCM-D substrate with band pass filter can be used to evaluate mm-Wave system including flip-chip bonded MMIC.

  • In this research, damage behavior of singly oriented ply (SOP) fiber metal laminate (FML) subject to concentrated load was studied. The static indentation tests were conducted to study fiber orientation effect on damage behavior of FML. During the static indentation tests, Acoustic Emission technique (AE) was adopted to study damage characteristics of FML. AE signals were obtained by using AE sensor with 150kHz resonance frequency and the signals were compared with indentation curves of FML. As fiber orientation angle increases, the crack initiation load of SOP FML increases because the stiffness induced by fiber orientation is increased. The penetration load of SOP FML is influenced by the deformation tendency and boundary conditions. Cumulative AE counts were well predicted crack initiation and crack propagation and AE amplitude were useful for prediction of damage failure mode. During the matrix cracking, fiber debonding and fiber breakage, AE amplitude has $45{\sim}60dB,\;60{\sim}80dB\;and\;90{\sim}100dB$, respectively.
