AND HUEY-RU CHUANG National Cheng Kung University Tainan, Taiwan, ROC Recently, multi-layer LTCC technology has been used extensively for the miniaturization of RF passive components and antennas. In addition to the high integration by embedding components and interconnects, high Q passive elements have been demonstrated with LTCC technology.1 It is suitable to integrate antennas and other pass...

The L-type calcium channel (LTCC) has a variety of physiological roles that are critical for the proper function of many cell types and organs. Recently, a member of the zinc-regulating family of proteins, ZnT-1, was recognized as an endogenous inhibitor of the LTCC, but its mechanism of action has not been elucidated. In the present study, using two-electrode voltage clamp recordings in Xenopu...

The mechanism by which ethosuximide reduces thalamic low-threshold calcium current (LTCC) was analyzed using voltage-clamp techniques in acutely isolated ventrobasal complex neurons from rats and guinea pigs. The ethosuximide-induced reduction of LTCC was voltage dependent: it was most pronounced at more-hyperpolarized potentials and did not affect the time course of activation or inactivation ...

In this study, a low-temperature co-fired ceramic (LTCC)-based direct current (DC)-DC converter is proposed for reducing stray inductance and mitigating electromagnetic interference. The dominant radiating loop of the LTCC-based DC-DC features multilayer design, which helps suppress noise sources reduce radiated emissions. peak voltage switching at frequency 500 kHz approximately 8.98% lower th...

LTCC technology has large benefits in microwave applications. Ceramic substrates as well as the gold and silver pastes have excellent physical and electrical properties. Moreover, material and processing costs are competitive to other substrate systems like HTCC and printed circuit boards. A comparison between LTCC and PCB is followed by a listing of commercial LTCC materials and a selection of...

In this contribution we deal with technology potential of the low temperature co-fired ceramic (LTCC) in association with design, development and production of organometallic thick film gas sensors. Customer demands to the gas sensors array and to the joint construction of the sensing part with evaluating ASIC led to the exploitation of LTCC potential in the production technology. The presented...

L-type voltage-gated Ca2+ channels (LTCC) couple neuronal excitation to gene transcription. LTCC activity is elevated by the cyclic AMP (cAMP)-dependent protein kinase (PKA) and depressed by the Ca2+-dependent phosphatase calcineurin (CaN), and both enzymes are localized to the channel by A-kinase anchoring protein 79/150 (AKAP79/150). AKAP79/150 anchoring of CaN also promotes LTCC activation o...

The paper presents general information on LTCC materials, manufacturing processes and properties of fired modules. A Multichip Module package has been the main application of Low Temperature Cofired Ceramic (LTCC) technology. Recently, this technology is also used for production of sensors, actuators and microsystems. The research and development on the LTCC sensors and microsystems carried out...

The increasing use of low temperature co-fired ceramic (LTCC) for the fabrication of biological microfluidic devices necessitates further research on LTCC biocompatibility. In this study we explore the inhibitory effect of DuPont’s 951 LTCC on Polymerase Chain Reaction (PCR), and demonstrate a novel mechanism to increase biocompatibility between LTCC and PCR with the addition of a common passiv...

For the development of force sensors, manufactured in LTCC (low temperature co-fired ceramics) technology for musical wind instruments, the mechanical properties of laminated LTCC tapes were characterized. Since one layer of LTCC tape is not always fulfilling the requirements of the force sensor’s loading capacity, the influence of lamination parameters for different number of layers were inves...
