This paper reports a novel method to produce high density feedthrough glass wafers with sufficient thickness for the packaging and interconnection of high density array micro electromechanical systems (MEMSs). Pyrex glass wafers with thin film metal lines on the surface are stacked and bonded with each other using phenyl methyl siloxane-based adhesive. The stacked glass wafer block is then slic...

We developed room-temperature bonding of micro-nanofluidic device using fluorine induced plasma activation method. Fluorine was induced by O2 reactive ion etching (RIE) plasma treatment with Teflon Pieces which increased the bonding strength between fused silica glass substrates. The room-temperature bonded fused silica glass micro-nanofluidic device had high bonding strength as well as could w...

objective: microleakage has always been a problem in restorative dentistry. to decrease microleakage, modern bonding systems, different application methods and sandwich technique have been recommended. the purpose of this study was to assess the microleakage in class v cavities restored with open sandwich technique using self-etch and total-etch bonding systems.   methods: in this in vitro stud...

This paper describes a simple process of adhesive bonding between a glass lid and a SU-8 microfluidic device. The bonding is made by applying pressure, between 1.24 MPa – 3.72 MPa, and heat above the SU-8 glass transition temperature (Tg). The advantages of this process are low cost, simplicity and no need of extra adhesive material, which could block microchannels and inlets. The SU-8 microcha...

Anisotropic conductive film (ACF) has been used for more than 30 years in flat panel display (FPD) module package. In this paper, the technical trends and development of ACF are described. Among all of them, ACF material design for flexible substrate bonding is critical for the development of flexible display. According to different process flow of flexible AMOLED, flexible substrate bonding te...

Introduction: The aim of the present study was to evaluate the effect of glass ceramic insert in the sandwich technique to reduce microleakage in class II composite resin restorations. Methods: Sixty sound human upper second premolars were selected and randomly divided into six groups (n=10). Class II box-only cavities were prepared in distal aspects of each tooth with gingival margin located a...

This article examines the development of a laser pretreatment method for glass fibre reinforced polypropylene surfaces for industrial applications. This work aims to create a reproducible surface for bonding low-energy polypropylene which adheres very poorly to most adhesives and forms to the matrix material for plastic composites. The combination of glass fibres with polypropylene in the form ...

The aim of this study was to deyelop a noyel hydroxyapatite (HA) coating method on zirconia using glass coating technique. A borosi)icate glass, the mixture of the glass ttnd HA (3e, 50, 70, and 90 mass%), and the 100% HA were coated on two kinds of zirconia discs and fired at 900-950'C. After the final coating, the surface of the sample was etched for 3 min in an acid-mixture of 3% HF and 5%HN...

Effective and cost favorable procedures for hermetical encapsulation of MEMS-structures on wafer level can be fabricated by wafer bonding technologies like the seal glass bonding and by suitable connection technologies routing the electrical potential through the chip structure. Within the paper the parameters of the print and bonding process will be presented and the print process limits will ...

The usages of the composite materials range from simple household to light-to-heavy industrial purposes including oilfield applications. The objective of this study is to evaluate current and potential uses of composite materials for the petroleum industry. This article gathered all the available composite materials that are normally used specially in oilfield and surface pipeline applications....
