Double sided adhesive tapes

This micro device consists of a round or square micro chamber machined in a bottom plate sealed by a cover slip with double-sided adhesive tape [23], Sound irradiation was achieved by a PZT disk below. The PZT disk was bonded by super glue to the surface of the micro chamber. The PZT disk was driven by an HP functional generator... 

This micro device consists of a square micro chamber which has as a bottom plate a conventional DNA micro-array chip sealed by a cover slip with double-sided adhesive tape (see Figure 1.26) [24], The adhesive tape serves as a spacing gasket to define the shape and dimensions of the chamber. The cover slip contains the air pockets with a uniform, pitched distribution. The air pockets trap the air bubbles... 

FIGURE 3.50 Side view of an EWOD device (not to scale). The bottom plate served as the base for a pattern of polysilicon EWOD electrodes (1 mm2, 4-pm gap) buried under the thermal oxide. A top plate was formed from ITO on glass both plates were coated with Teflon-AF. The plates were joined with double-sided adhesive tape as a spacer [518], Reprinted with permission from the American Chemical Society. 

Indomethacin and paracetamol loaded spheroids/beads were prepared by a standard spheronization technique employing an Alexanderwert extruder and a Caleva spheronizer fitted with an 8.5 inch radial plate and a base spheroid composition of 50 50 microcrystalline cellulose (Avicel PH101, PMC) and Lactose BP (Wey Products Ltd), respectively. The average diameter of the spheroids was of the order of 1.1 mm as determined by light microscopy. For the SSIMS analysis the spheroids were placed in a close-packed arrangement on the sample holder secured by double sided adhesive tape. 

The interior of spent cartridge cases were sampled by dry swabbing with 0.25 g of acrilan fiber for FAAS analysis (dry swabbing) or by double-sided adhesive tape (Scotch pressure sensitive tape) on the end of a suitable diameter... 

Unless stated otherwise, hands were sampled by tape lift (adhesive stub) for inorganic FDR using a 13-mm-diameter aluminum SEM sample stub with double-sided adhesive tape attached (Scotch pressure sensitive tape). Sampling of the hands and face in the outdoor firing tests in Chapter 26 employed acrilan fiber damped with isopropanol (IPA) as per the suspect sampling kit detailed in reference 190. 

A double-side adhesive tape was prepared using a mixture of a hydroxylterminated poly butadiene, a polyol, and an isocyanate compound containing an oxadiazinetrione ring 241 A compound suitable for sealing spaced glass panels comprises a reaction product of an unsaturated polymer with functional end groups with HTPB, a decane thiol adduct, and tolylene diisocyanate 242). 

The physical structures of spray-dried and freeze-dried amorphous and crystalline (humidified over 54.5, 65.6 and 76.1% RVP for 144 h for spray-dried and 72 h for freeze-dried) lactose were viewed by SEM (JSM-840, Tokyo, Japan). Small amounts of samples were mounted on SEM specimen stubs by using double-sided adhesive tape. The mounted samples were then coated with gold in a sputter coater (Edwards sputter coater, Sussex, UK) under high vacuum. The coated samples were viewed with SEM at 20 KV in the secondary electron mode. The samples were systematically viewed at 500 to 10,000 X magnifications. 

Adhesive tapes Apart from the application of the liquid adhesive systems described, it should not be forgotten that many bonding problems can be solved by double-sided adhesive tapes. The development of these systems, especially on the basis of adhesive foam structures or thermal post-curing, has made great advances in the past with regard to strength and possible stresses. 

Abhesives Coatings based on special silicone compounds with adhesive layer resistant properties on, for example, release papers. Application as substrate for adhesive labels, double-sided adhesive tapes, and so on. 

Double-sided adhesive tapes (G L Precision Die Cutting, Inc. San Jose, Cat. No. GL-187) are used for making adhesive layers on the backing plate. 

Preparation of Adhesive Cards 1. Put double-sided adhesive tapes on one side of the support cards (fee Note 14). 2. Cut the adhesive board into 7.5 x 30 cm2 strips to make adhesive cards.

An ideal bond coat should have several characteristics that include uncompromised biocompatibility, good adhesion to both the metal substrate and the osseoconductive top coat, and a well-defined melting point to allow application of thermal spray technology. The adhesive function of the bond coat has been loosely compared to the action of a double-sided adhesive tape. 

Bonding with microstructured double-sided adhesive tapes (not a truly reversible bond, but also not strictly irreversible)... 

In this approach, the glass chip and the thermoplastic microfluidic scaffold are bonded together by a double-sided adhesive tape. The bonding is done at room temperature allowing deposition of biomolecules on the sensor chip before sealing the system. The tape had to meet certain criteria to qualify as a sealing tape. 

For completeness, it should be mentioned that there are adhesive transfer tapes. The adhesive layer is protected by two removable liners. This transfer adhesive may be a choice if very thin channels are required not allowing for accommodation of a double-sided adhesive tape with a stabilizing polymer substrate between the two adhesive layers. Transfer adhesive tapes can also be used for self-made double-sided adhesive tapes with a nonstandard substrate material. 

Laser Cutting The same UV laser system as for cutting the PDMS gaskets was used to structure the microfluidic channels into the double-sided adhesive tape. But for cutting of microchannels, a UV laser is recommended to achieve the required liner lateral resolution, particularly for cutting through a real double-sided adhesive tape (one substrate with two adhesive layers and two liners on each side). 

Laser cutting allows for almost free design of the microfluidic channels in the tape gasket. Figure 5 shows laser-cut double-sided adhesive tapes with microfluidic channels. The tape adhesive is still protected by its liners. The tape cutting can also be depth sensitive, i.e., kiss-cuts down to the carrier liner can be done if the tape roll is used in further automated roll-to-chip or manual tape-to-chip bonding processes. 

The laser-cutting process for silicone gasket membranes and double-sided adhesive tape gaskets will be developed further. Ultrashort pulse lasers are becoming commercially viable allowing direct microchannel ablation even in transparent thermoplastics like PMMA, COC, or... 

Scanning electron microscope (SEM) systems are ideal for a pictorial representation of morphological features of single layers of multilayered paint samples (particularly those not well contrasted by optical microscopy as the white ones) obtained by the contrast of secondary (SE) and backscattered electrons (BSE). An important advantage of SEM is the ability to analyze even the smallest smears for this purpose the smears are lifted from the underlying material using double-sided adhesive tape transferred to the sample holder (e.g., slide). Twenty micrometers microtome sections of paint cross-sections are recommended. In order to avoid electrical charging the samples have to be carbon coated or transferred into the chamber of a low vacuum system. 

In 1984, fast atom bombardment (FAB) spectra were directly recorded from the layer after addition of a matrix, for example, (thio)glycerol or m-nitrobenzylalcohol, onto the zone [40,41]. Using a double-sided adhesive tape, either a cut section of the TLC foil or the removed adsorbent were fixed on a... 

As DESI works under ambient conditions, preparation of the TLC plate is usually limited to its firm attachment to the moving table by the aid of double-sided adhesive tape. Another crucial step is to find the exact starting position for the analysis. To achieve this, it is advisable to mark the point near the start of the separation lane with an easily ionizable substance. A small dot of Rhodamine B (MW = 442) from a red... 

ESCA measurements were performed on ESCA 100 (USW Manchester) using MgK radiation of 1253.6 eV under pressure of 10 bar. Cls=284.5 eV was applied as an internal standard. The samples were fixed to the sample holder using the double-sided adhesive tape. The original ESCA curves were numerically deconvoluted into components of mixed Gaussian-Lorentzian shape. 

Mount sample directly on sample holder with the surface of interest exposed on top and adjust doR-FP to 10 mm see Fig. 9.3a). Small clamps and single- and double-sided adhesion tape often enable easy mounting. TCAUTION ...
