Carrier foil

As the sample has to be supported with thin carrier foils, the question arises whether they can act sufficiently as a barrier for oxygen. The time lag t for the first... [Pg.740]

Alternatively, ultrathin copper RCC may be used. Carrier foil, usually copper foil of IQ-jim thickness (2 oz.), is coated with a very thin layer (10 to 20 m) of current conductive release film, and a thin foil of 3 to 5 pm is plated. After such RCC is laminated to the core, the carrier film is peeled off and the surface condition is the same as etched-down copper. Drilling speed in this direct CO2 laser drilling method is degraded by 30 to 40 percent compared to that of straight resin drilling, but the registration to the capture pad is ensured. [Pg.501]

For example, colorful logos are directly applied to the mold surface using carrier foil. The melting plastic material bonds permanently with the foil during the processing. It is more welded than glued, which means that the applied decorations are scratch resistant and almost indestructible. [Pg.199]

The sensor needs to withstand mechanical stress during time of wear. Integrity of sensor carrier foils or wires, typically 30 to 300 pm in thickness and conductive traces, typically 50 to 500 pm in width, needs to be guaranteed for reliable sensor function and for complete sensor extraction. [Pg.47]

Imaging plates are exposed similar to radiographic films. They are read out by a LASER-scanner to a digital image without any developing process. After optical erasing of the virtual picture the same IP can be used cyclic up to more than 1000 times. The life time is limited by the mechanical stability of the IP s. An IP consists of a flexible polymer carrier which is coated with the sensitive layer. This layer is covered with a thin transparent protective foil. [Pg.468]

A schematic cross-section of a p-i-n a-Si H solar cell [11] is shown in Figure 72a. In this so-called superstrate configuration (the light is incident from above), the material onto which the solar cell structure is deposited, usually glass, also serves as a window to the cell. In a substrate configuration the carrier onto which the solar cell structure is deposited forms the back side of the solar cell. The carrier usually is stainless steel, but flexible materials such as metal-coated polymer foil (e.g. polyimid) ora very thin metal make the whole structure flexible [11]. [Pg.170]

CapiUary blotting is recommended, if the gel is mounted onto a impermeable carrier. Put the affinity membrane with the coated face towards the gel onto the gel, cover the backside of the membrane with several layers of dry filter paper, wrap the stack into a water-tight foil, and store it under moderate pressure in a refrigerator for several hours or overnight. [Pg.78]

Metal hydrogenation catalysts may be employed in any one of a variety of forms (a) macroscopic forms as wires, foils or granules (b) microscopic forms as powders obtained by chemical reduction, colloidal suspensions, blacks or evaporated metal films (c) supported catalysts where varying concentrations of metal are dispersed to a varying degree on a carrier such as alumina, silica or carbon. [Pg.3]

The irradiated sample and the polyethylene container in which it was irradiated, along with mercury carrier, are wet-ashed with a mixture of nitric, sulfuric, and perchloric acids under good reflux conditions. The mercury is isolated from the digest by precipitation as mercuric sulfide and is purified by electrodeposition as elemental mercury on gold foil, which is then counted for 197Hg and 24-hr 197mHg x- and y-ray activity with a thin Nal detector. [Pg.98]

The influence of the reactor temperature on the conversion of methane was examined during pulsed operation. The heat performance of the foil heater was slowly increased while the reactor was continuously supplied with gas pulses consisting of pure oxygen at 129.5 ml min-1 together with a flow of methane (0.5 ml min-1). The volume flow of the carrier gas nitrogen was adjusted to 130 ml min-1 at atmospheric pressure, delivering a residence time in the coated spiral of 0.4 s. The cat-... [Pg.113]
