Silicon wafers are actually semiconductor devices that are heavily used in todays electronics. To some, these micro devices may seem dismissible but they really have important uses in technology. Silicon wafers are primarily used in manufacturing computer chips. Every electronic device that you enjoy these days contains these tiny yet very significant wafers.

Generally, silicon is a good conductor of electricity. If you have it altered, not only will it conduct electricity, you can also make good use of it as an effective insulator. Whats amazing about these sophisticated wafers is that manufacturers only use regular beach sand particles as the main ingredient in the manufacturing process. Everyone knows that sand also acts as a lightning conductor, and the same technology is also utilized in both computer and electronic circuit boards.

The sand used in the wafer manufacturing process is being closely monitored. It must be kept clean at all times, free from any debris. Whenever the manufacturing process is contaminated due to foreign material inclusion, wafers with faulty connections are created. These bad wafers are costly mistakes, thus the manufacturing of silicon wafers must take place in a strictly regulated environment. It must be handled with extreme care by professional and experienced technicians.

Technically, the device can be described as a thin, circular disc mainly used in the semiconductor and integrated circuit manufacturing. There are also other recognized types in the industry like the Gallium Arsenide or the SOI, which is basically silicon on insulator. These are also utilized in electronics, requiring a careful and thorough manufacturing for efficient end products.

Specialized companies that operate a MEMS foundry create these devices. During the manufacturing process of the thin film, the wafers produced can come in various sizes and desired specifications. The composition can include so many components before the fabrication is completed. After this, the finished product is then packaged carefully for distribution.

A special compound is used to clean the finished product. It guarantees consistency so it will not be altered in any way. The cleaner material used is some weak acid adequate enough to remove impurities of any kind. It also takes care of the various issues within the sawing process.

The various sizes in the finished products make up for the different applications, though they are generally determined based on the components mechanical strengths. And even though the sizes vary, these wafers are manufactured in between 100 mm. to about 300 mm. in diameter. These parts and pieces vary in their costs and dependent of course on the size and usage.

The machinery involved in the manufacturing and cutting of these parts can cost a fortune, or likely that of a small factory. Manufacturing and perfecting such small but vital electronic components costs a great deal. There is no other way of going around the process just to save on the manufacturing costs at the least.

All these tiny yet important pieces are integrated in various electronic applications all over the world today. Computer systems are among the obvious benefactors, including mobile phone technology and digital appliances. There is a clear revolution in the world of electronics and silicon wafers are at the forefront, continuously doing wonders for this electronics-dependent world.

Electronic Control Module Tuning With The Unichip Q

Comments Disabled

The up to date Sequential Electronic Fuel Injection Control System is made of sensors which observe the actual engine requirements, the Powertrain Control Module (PCM) which operates the particular system primarily based on return signals from these electrical feedback sensors, as well as actuators which are powered under the control of the actual ECM.

The ECU (Engine Computer) carries out activities such as fuel injection control, idle air control, and spark ignition control.

In addition, the Powertrain Control Module is loaded with many different diagnostic test settings which usually streamline trouble shooting any time a new trouble code appears.

The two most common calibraion tables that you need to manipulate or modify is undoubtedly the timing map and as well fuel map

Ignition timing control

The ignition power transistor placed located in the ignition main circuit turns ON and OFF in order to regulate the main current rate to the ignition coil. This controls the ignition timing so that it will generate the optimal ignition timing with regard to the engine performing conditions. The actual ignition timing is determined by the ECM (aka The Blackbox) as a result of rotational speed, air flow, engine coolant temperature (ECT), and atmospheric pressure.

Injector control

The injector open milliseconds (MS) as well as injection timing remain controlled so that the perfect air to fuel mixture is delivered to the engine to correspond to the continually-changing engine operating conditions. A correctly scaled injector is mounted in the intake port of each cylinder. Petrol is sent while under pressure (around 55 psi) coming from the gasoline tank to the actual fuel injectors through the fuel pump motor, with the actual pressure being regulated by the fuel pressure regulater at around 55 psi. The controlled fuel is then distributed evenly to each one of the injectors. Sequential fuel injection is usually performed one time for every cylinder per two rotations of the crankshaft. On a four cylindr engine the firing order will be 1-3-4-2. Each cylinder has a dedicated gasoline injector. This is known as multiport injection. The ECM (Engine Computer) provides a richer air/fuel mixture by carrying out “open-loop” control when the engine is cold or operating under high load conditions in order to maintain engine performance.In addition, when the engine is under normal operating temperature after warming-up, the ECM manages the air/fuel mixture using the heated Lambda sensor signal to handle “closed-loop” control. The closed-loop feedback accomplishes the theoretical Air-fuel mixture ratio where the catalytic converter can obtain the absolute maximum clean-up operation.

Using the Unichip Q-plus you will have total control over these variables to make alterations to the timing and fuel calibrations. The Unichip PnP has 24 RPM sites between 100 RPM and 24000 RPM and 13 load sites between closed throttle full throttle position. This equates to 312 available tuning points for each map. In turn the Unichip PnP is going to interpolate in between each speed and load site 16 times which gives a decent resolution densed map.

UniQ is Unichips most recently released software package for tuning engine ECU’s. This software program is a revolutionary change from old style DOS model which had been in operation for over a decade. Take the Unichip Tuning software for a test drive and see for youself.

The Development Of The Electric Bass Guitar

Comments Disabled

Although the concept of a bass guitar was first developed in the 1930s, it wasn’t until the 1950s that mass production met with popularity and the concept of an electric bass guitar became mainstream. Once the idea of an electric bass guitar took hold, and was used widely in groups and bands performing across the world, many companies began developing new styles and methods to create some fantastic ideas for the instrument, and help its popularity grow. Today the electric bass guitar has stepped forwards from the dark shadows of the back of the stage to take a much more prominent position at the front – and has become known as a very popular and stylish instrument to play. Not forgetting, of course, that the quality of sound and versatility have come a long way too.

Since it took about twenty years for the idea of an electric bass guitar to become a mainstream popular idea, it is unsurprising perhaps that it took another twenty years for the next big jump in design and innovation. It was in the 1970s that the company known as Music Man was founded by Leo Fender. It was this company that designed and created the StingRay, which was the first bass guitar to include active electronics. Although these active electronics can sound quite complex, the simple effect was to increase the range of high and low notes, and enhance the crispness of each.

In the early seventies a company called Alembic created the basic design for the high end bass guitars, known as boutique guitars. These were crafted using the highest degree of expertise, with the most highly skilled craftsmen using the finest quality materials. With unique, custom designs, the most premium woods available and some of the most innovative electronic gadgetry included, these boutique bass guitars became well known as the top guitar to have – and brought bass guitars from the back of the stage to the very front – an equal to the standard electric guitar.

Over the next thirty years the designs of electric bass guitars have varied, with new innovations, odd and unusual features and designs, including a headless bass by Ned Steinberger, who also introduced the Trans-Trem tremolo bar. A few years later the Guild Guitar Corporation introduced the astonishing fretless bass, known as the Ashbory. Quite how a guitar would work without frets would challenge any sane thinker – but the Ashbory used silicone rubber strings, with a piezoelectric pickup. The result of this was a sound more like a double bass than an electric guitar.

It was in the nineties that five string basses became popular, and prices began to reduce quite significantly, seeing pre-amplifiers built in to most bass guitars – previously something reserved for the higher end guitar. Today we see electric bass guitars include digital modelling circuits actually built in to the guitar – almost like having a computer built in to the body of the guitar, and able to enhance, distort, amplify and altar the voice of the guitar in such a way that it is possible to program the guitar to sound like any of the well known types of guitar available previously.
