In recent years in industrialized countries are experiencing significant growth in the electronics industry, and the time for the knowledge they gained is doubled, while the existing technology obsolete at the moment less than five years. In digital electronics there is an even more rapid development. And one of the most important moments in the development of digital, as indeed, analog electronics is the development of automated systems, printed circuit board design. A leading source for info: Ali Partovi. And although to date all the more or less developed western world uses powerful systems and software for printed circuit boards in the territory of the former Soviet Union there slight lag in this area. The most common to date the program for the development of printed circuit boards is a cad P cad. The latest version of the cad is a software package P cad 2006, Altium Limited Company on announced the termination of development of P cad, and instead offers users use the Altium Designer..
This is important because solid part can be primitive “pick up” all the heat – and thus, at the solder will not create a sufficient temperature. A heating element of the whole as a whole can at times not only for purely technical reasons, but also due to fire hazard and the effect of thermal expansion, which can bury all the efforts made by low-power soldering station. Also important is the question of the supply voltage. Standard characteristics of domestic and many industrial electric systems in Russia – is 220V, 50Hz, but the sealing parts in locations far from power grids – in a car or other places where, until the socket is not , you can use soldering stations, fed by voltage 12, 18 or 24. And of course, most important, perhaps, characteristic of a soldering iron or soldering station is the operating temperature device. The most primitive models have no stable temperature, but with little heating of soldering when the solder does not melt to a state of fluidity and does not fill all the pores in the place of contact, you can get very frequent effect, which is calling the Cold soldering ‘.
Soldered place looks dull, it becomes rough to the touch – a compound itself turns fragile and unreliable. To avoid this, use a soldering station with an operating temperature sufficient to specific type of material. Overheated sting accelerated wear of the soldering iron or a corresponding nozzle in the case of soldering station, solder may overheat and boil, covered by the end of the sting of dross, flux substrate was completely burned. It happens that the sting of the nozzle at the soldering station is overheating due to excessive evaporation of the solder, if so, work with small electronic components on such a nozzle is not possible. Huge advantage of soldering stations to make a simple soldering iron is that even if you accidentally adjusted the device incorrectly, you always have the opportunity to change the nozzle. Well and good work of the working part of the soldering station have low or too high temperature is difficult, so take a look at the indicators. They will help you configure soldering station on the correct mode, while using an ordinary soldering iron you denied such a possibility. With frequent use of the equipment for soldering master must either buy a set of soldering various capacities, either – modern soldering station with a temperature control, set temperature and a convenient stand for your soldering iron. In addition, perhaps the person involved in soldering constantly delight such details as bath sponges for cleaning, antistatic protection and some other possibilities. A quality soldering station for understandable reasons worth some money, but buying a set of different soldering irons that entails the acquisition of attachments, certain types of solder, which requires skills contact with the equipment at different levels, hardly a better job. The current level of technology allows you to select successfully applied a model from a wide range of devices specifically for your needs – from a relatively thin samples Weller to a wide range Aktakoma, which includes samples from a miniature home soldering stations, to the powerful professional equipment. Therefore, when you visit a specific store or online store, you can choose optimally suitable option soldering station.
For instance, if we have a 1 megapixel camera, the images that we get should be around 10×15 cm., From 1.3 to 1.5 megapixel image will be 13×18, and so it goes. So we have to evaluate is what kind of use we will give our camera. If 99% of the photos are to be sent by mail or posting on the Web, with a 1 megapixel camera will suffice, but if our intention is to make prints larger than those listed above, we advance in the scale of megapixels. In the table below, we have the approximate characteristics of the resolutions by the number of megapixels of the camera. Keep in mind that if you want to print to a size greater than specified, the image lose quality and “pixel” that is, when you print the image you’ll notice the points that form them, as they will be too big for that size. Camera Lens After resolution, the most important factor to consider is the lens. To get good photos, the camera should have quality optics (glass, no plastic). Like the cheaper 35mm cameras, some digital cameras bring fixed lens (no zoom type), ie, the lens always stays in the same position and at the same angle of vision. The only way here is to change the frame for a picture, it is closer or further away from the subject or reason to photography. For example: we can not always approach everything we want our subject, and when we are, most of the fixed lenses act like wide angle, which means that at a short distance will produce a significant distortion in the picture (the nose are larger, the eyes are separated, and the faces seem as if bent toward the camera).
Here are several mailing lists for free that lets you send information to other members. 7.-Signatures Each year there are seven billion e-mails, I’m sure you also sends some truth? Firms indirectly attract the people we contacted daily, these are located at the end of each outgoing message and are a good option to increase their sales and get customers. Each recipient of a particular content becomes a potential customer. A good example is Hotmail, through this technique to promote managed more than 12 million customers in just 18 months, as he did? The method was as simple as including the end of every message you sent any of its subscribers the note your e-mail free. In this way, each subscriber has become a sales agent (involuntarily). Then do not forget to set your email (you can do with tools or options menu) and include your signature on all e-mails you send. 8.-ads in search engines and directories.
This method of promotion is the introduction of prominent ads in major Internet search engines like Google, Yahoo (Overture), or Microsoft MSN, each time a user searches the advertisement appears to the right of your monitor and if the user clicks on any of these ads, that action is costing the advertiser (pay-per-click), it is best that publicity is exposed only to a target audience (country is determined by language, region and keyword) will get a market that is really interested in the product or service that these marketing. It is a practical way to find customers searching for what you offer. Obviously this service has a cost ranging from $ 0.01, $ 0.05 more per click (visit only). It is worth noting that Google has had enormous success with its AdWords advertising service, if you hire the services of your Google AdWords ads appear in a column on the right side of your browser marked “Sponsored Links.” You can also view the sites affiliated with the search network and content marked as “Ads by Google ‘. 9 .- Marketing offline.
(Promotion in traditional media) to call offline marketing promotion in traditional media like newspapers, television, radio, magazines, leaflets, posters, cards, marquees, etc. While it is true that online advertising is going up like wildfire offline promotions can be profitable even always know where to go when your potential customers, to place their advertising. Even the mainstream media have their limitations and a higher cost than online promotion allow us access to a market sector that could not normally reach through virtual means, we must also take into account that the mainstream media, especially print media is highly profitable for a web business focused on the local market. A self to achieve a successful result in the issuance of a warning is important to locate those specialized in the field means that the website is dedicated item or product or service For example, if you’re selling computers can not think of publishing a notice in a pet magazine. Not require a large budget to promote off line, since we can include our website commonly used stationery and business cards, envelopes, brochures and product catalogs, letterheads, ads, signs on car window stickers, etc. otherwise we are wasting the opportunity to communicate our presence online to many people in our midst.
