Characterization of direct patterned Ag circuits for RF application

Rheological Behaviors and Their Correlation with Printing Performance of Silver Paste for LTCC Tape

“…The printing process are done only at the place where required and follow the design pattern which are prepared earlier (Vasudivan & Zhiping, 2010). The printing quality and the fine line printing resolution patterns is necessary in order to achieve high component density and high frequency applications (Dubey, 1975;Kim et al, 2010). Successful transferred pattern onto the substrate depends on the rheology of the paste material.…”

Electrochemical migration of directly printed Ag electrodes using Ag paste with epoxy binder

“…3, the main factor that affected the phenomena of interparticle necking and coarsening was the sintering temperature. screen printing, ink-jet printing, and gravure printing), and could therefore be one of their most distinguishable features and disadvantages [12]. Fig.…”

30-GHz High-Frequency Application of Screen Printed Interconnects on an Organic Substrate

“…Yet the electrical performances of printed traces in the higher frequency range (gigahertz range) have been subjected to little investigation to date [2]. Rather, work abounds on the effect of sintering conditions on the DC electrical resistivity of printed traces [2]- [7], due to the applications considered which are in the lower frequency domain (e.g.…”

“…RFID tags operating at megahertz frequencies, solar cells). While Kim et al [2] reported the RF characterization of inkjet-printed transmission lines up to 30 GHz on silicon, little information was available on whether the RF results were realistic or within a reasonable benchmark. In addition, Salmeron et al [8] used a 2.5D electromagnetic simulator to evaluate the electrical performance of transmission lines against the fabricated structures, but only up to a frequency of 1.2 GHz.…”

“…The RF measurements are validated with simulation models which take into account non-ideal transmission line characteristics (typically neglected during the design and modelling process), so as to accurately predict the RF response. To date, there exists little literature which reports on the DC conductivity variation of printed samples across a substrate, since most researchers focus on measuring samples for repeatability [2], or samples of a different variety [9], [10]. …”
