Electronics printing efficiencies

For a long time, these auto-routers have been a standard tool in the electronics industry. They are applied in the design phase of electronic printed boards. An electronic router calculates the most efficient layout of an electronic pathway considering obstacles and predefined constraints. 

Near-infrared-active materials such as phthalocyanines are becoming especially important in materials of this type, because they permit the use of infrared diode lasers (which are compact, inexpensive, and easily modulated) for electronic printing applications such materials can have quantum efficiencies (electron-hole pairs produced per photon absorbed) near unity and near-infrared sensitivities (for 50% discharge) of about 1 erg/cm. There are worldwide efforts underway, however, to produce usable visible-light diode lasers. 

The Internet advertising mechanism works much the same way as its "real world" counterpart. Company Homepages are electronic brochures and are disseminated by using new methods. But the methods are actually not new, they are basically the same as those used in printed journals This is efficiently done on an online Journal like NDTnet where advertising is concentrated in a virtual NDT Exhibition that attracts many readers to the site. The exhibitors have had good experiences with their presentations In contrast to individual Homepages which may often experience minimal traffic, NDTnet is visited by more than 6000 readers each month. Links to its exhibitors Homepages increase the audience and the information available. 

Such units are used in the watches with electronic drives instead of the traditional mechanical spring driven drives. Another area where the combination function is being used is in large-scale integrated circuit unit supports where the complex interconnection requirements make a combination circuit support and printed circuit unit an attractive way to achieve high packing efficiency such as computer hardware systems. 

Larger 3- and 4-m.e.v. Dynamitron electron beam accelerators are likewise available commercially. Service capabilities increase with the m.e.v. level of the electron beam accelerator. A 3.0-m.e.v. Dynamitron electron beam accelerator furnishes radiation capable of penetrating a maximum 370 mils of a unit density material or 185 mils of 2.0-density material other performance capabilities are doubled as well. The overwhelming majority of polyolefin plastic products now being manufactured have section thicknesses which can be penetrated safely even by a 1.5-m.e.v. electron beam accelerator. Two possible exceptions would be printed circuit board and thick-walled pipe. A 3-m.e.v. accelerator could readily meet such requirements. The performance capabilities of the 3-m.e.v. accelerator (12-ma. power supply) are increased not only with respect to maximum depth of penetration but also processing capability, which amounts to 14,000 megarad-pounds per hour at 50% absorption efficiency. 

Printing out electronic records and archiving them in paper format will be an option when only a limited amount of data has to archived, and there is no need to maintain the processeable data. In this case, printing and signing off for the correctness of the printout may be a valid and efficient procedure. 

The objective of printed electronies is to ereate new mass markets for eost-efficient electronics, without attempting to eompete with silicon electronics, which would be a hopeless endeavour anyway.
