ign="center"> Modelmakers make it possible for big ideas to be encapsulated in a size and range that can be grasped by common observers. Most designers of models create small-scale replicas of buildings, airplanes and other transportation equipment, real estate projects and even cities. Some models are used to describe processes and systems of production. Others are relied upon by inventors and scientists to propose their ideas to a particular audience. To date, the most widely-used models are those concerning railroads. This has been crucial in determining the route and the area covered of this type of transportation system. It also gives engineers and other specialists a complete view of the...

We have seen it at some point or the other, companies coming out with cheap cell phones and capturing the market completely, making other mobile manufacturers come out with their own line of economic phone models.

Getting out on the waters is not what it used to be. Now it's better! Previously, whether you were getting out on your small fishing boat, or taking a team out for a fishing expedition, you basically would have to depend on a radio and the trusted waters to get you to and from your destinations. But now many fishermen are relying on GPS charting systems to help them navigate the waters. This way, they can focus on their task at hand and leave navigation to the experts. GPS Charting Systems on the Market There are a few marine navigation devices on the market that fishermen are using to not only help them find their way through endless waters, but also find the very fish their looking for under the...

The use of conductive epoxies in the electronic industry is becoming more and more common as the number of new epoxy systems on the market increases. Epoxies filled with nickel, carbon and silver are used for chip bonding, die attachment and many other applications. Silver filled epoxy presents best conductivity but is also most expensive. In 1966, Epoxy Technology was the first company to promote silver-filled epoxy resins as die-attach materials. Prior to this time, all dice were bonded to metal or ceramic substrates by means of eutectic alloys. Most (more than 90%) of the electrically conductive adhesives for die bonding are isotropic materials that conduct electricity in the in-plane and out-of...

With advancements in computer technology, why should keyboards be any different? Today’s keyboards don’t come with all the body:paraphernalia of attaching them to the main system. They are more simplified and come with a no-nonsense USB cord that can just be plugged in for your use. The I Ball USB Soft Touch USB keyboard is an example of such a keyboard that is making waves in the industry. Earlier keyboards were connected via a serial cable that went into a serial port behind the CPU. With a USB keyboard all you need is a free USB port to plug it in via a USB lead and you’re done. These are simple plug-and-play devices that can be plugged in or out as and when required. If it is plugged out...

Instead of wasting time and money by paying someone else to unlock your cell phone, you can do it by yourself in a little time. It is quite easy, and you don't need to be an expert to do it either. Check whether you have a CDMA phone or a GSM phone, though, before you start trying to unlock a cell phone. CDMA phones cannot be unlocked, as they have no SIM cards and they need authentication from the service provider to operate. Unlocking cell phones that are GSM, which make...

Computers are a vital in most industries; No longer is the PC just a piece of office equipment they are used in almost every industry and environment imaginable from the factory floor to the hospital ward. Computer control and data storage makes most functions and processes easier and more efficient but using PCs in many surroundings does pose problems. The harsh elements of an industrial area can damage a PC so they and the monitors have to be protected - often in some form of industrial computer enclosure and LCD enclosure.

Backlit displays are also popular with products aimed at older customers. As we grow older, our visual acuity fades. This is especially noticeable in low light conditions. Using larger keys with bold graphics make the controls more visible, but sometimes large control schemes may not integrate well into the overall product design. Molded...

Imagine walking up to a familiar Automated Teller Machine - perhaps on your way to work or while shopping, and apparently conducting a transaction just as you have hundreds of times before, only to find that you have unwittingly given thieves information that will allow them to empty your checking or savings account. It is a scary thought, yet one that is becoming increasingly real. Here is how the scam works. The thieves install a skimming device over top of the existing card slot at the targeted ATM. The false card slot is made to match the color and texture of the ATM and is very thin so it does not change the profile of the machine in a noticeable way once installed. The device actually contains...

Recently, manufacturers have started to move away from ordering molded keypads as separate components for their equipment interfaces. Instead they are saving time and money by ordering entire control assemblies that include keypad and circuitry. Faster Equipment Manufacture Time is money and if a manufacturer can produce a device faster, that translates to lower expenses and greater profits. Process optimization leads to more efficient production lines that is important during these highly competitive times. Even a small advantage translates to major savings for a company when performed over large production runs. Using keypad assemblies rather than separate molded keypads, circuit boards and...

Have you ever stopped to think about the lowly keypad? But when you do think about it, it's not such a lowly item after all. Keypads are a fixture in our daily lives--look around the house--keypads are on telephones, calculators, the security system, garage door, computers, microwaves, washers, dryers, TV remotes, game consoles. The list goes on and on. The first calculators started with our fingers and toes for smaller numbers and evolved to the abacus for larger numbers (2700-2300 BC). The first mechanical calculator was invented in 1623. Fast forward to the 1850's when the first successful key-driven adding and calculating machine was invented. This could be the beginning of the first keys and...

There are a lot of things we use every day that is made of silicone that we never think about such as cell phone key pads, the buttons on your remote control, baking dishes and utensils, prosthetics and your computer's keyboard. There are many advantages to using discount silicone parts such as they are good for extreme temperatures. This means it takes between 180°F and 600°F to burn silicone depending on the product they are used on. For instance, some microwaves contain silicone keypads. Even though they use microwaves to heat your food, sometimes the heat from the microwave can escape and heat up the keypad.

Humans are visual creatures and the design of molded keypads has to consider the look of the controls as much as their function. Well-designed keypad graphics contribute significantly to ease of operation and user satisfaction. Designing Keys to Accommodate Graphics In most cases, it is best to apply graphics directly onto the keys of molded keypads. It eliminates any ambiguity to a button's function. The graphics are applied to the surface of the key and then in the final curing process, the inks bind with the silicone to create a durable graphic that will stand up to normal use. Ideally, flat keys are the best surface for the silk-screening used. However in many cases, the manufacturer prefers the...

The best way to design the molded keypads for your equipment is to understand each component and how it contributes to keypad function. In this entry we look at the materials Si Tech uses in our keypad contacts. Understanding Contacts Underneath the surface of molded keypads is the circuit board that controls the device's operation. Beneath each key is an open circuit. Pressing a key causes the contact underneath the key to come into contact with the circuit board, closing the circuit. When choosing a contact material the two most important factors are conduction resistance and activation life. Every component in an electrical circuit adds some resistance and for most components that resistance...

Producing a finished product from concept to shelf is a long process. At some point the design needs to leave the world of drawing and become a three dimensional object. This step should not wait until final production. Creating of a prototype, either a non-working mockup or a functional test object, is a critical part of the design process. Design Evaluation It is surprising how often a design that looks good on paper comes off as clumsy when actually produced. There is something about the way our brains translate two-dimensional images into three-dimensional concepts that sometimes misses the mark. We need to look at the finished object to get a feel for how the consumer will react to it. The...
