Based on our results, we can design the packaging process flow so as to get reliable hermetic packaged MEMS devices by using low temperature fluxless In Ag wafer bonding.
To assess the suitability and safety of a novel suture-less hermetic docking head (HDH) device for aortic anastomosis, and to test it in vitro, on cadavers, and in animals.
Other applications include fabrication of hermetic seals in medical devices, and assembly of joints in applications where the final appearance is important, such as with acrylic or polycarbonate display cases and isolation glove boxes.
The implanted device included a hermetic titanium case containing a 15-channel stimulator and receiver chip and discrete circuit components.
Fig. 2 Mean live insects/100 g grains in hermetic and non-hermetical at different storage periods.
In this study, the focus was on the design for reliable wafer level hermetic Sn-Au based interconnection for MEMS devices by optimizing the contact metallization structures.
A circular cylindrical cavity enclosed by a thin elastic shell is found in many practical devices such as expansion volume mufflers, hermetic compressors and aircraft cabins.
Since the device can operate in atmospheric pressure, a hermetic seal is not required.
UNCD is suitable for application as a hermetic coating for protection of implantable artificial retina medical devices, and also contributes to improvement of neural stem cell (NSC -based cell traNSC -basedon, tissue engineering for neural tissue repair and regeneration and study of neural cell differentransplantation
To assemble the electrodeposition-based electrochromic device, DMSO-based gel electrolyte was contained in a hermetic square space of 20 mm × 20 mm, cut inside a 0.5-mm thick Teflon sheet, and sealed by sandwiching the Teflon sheet between two FTO electrodes (one of which was modified with TiO2 nanoparticles).
Moreover, devices assembled in TO220 package without flame retardant components in the molding compound performed better than devices assembled in other TO220 packages, or assembled in hermetic TO3 package, pointing out the role played by the interface between the green molding compound and the top passivation layer in the long term parametric stability.
