Custom Silicone Rubber Keypads Design Considerations For Engineers

From landline phones, cell phones, computer keypads, household appliances and more you will find silicone rubber keypads. Silicone rubber is versatile which makes it easy to use in so many gadgets and devices. Silicone Rubber Keypads are so common that many people don't even notice how many times they are coming into contact with one.

There are many ways to mold silicone rubber keypads which makes it easy for manufacturers to incorporate them into an end product. Today's consumers, like you, are used to having choices and one choice is how the product feels.

As hard as they try, electronic engineers try to find standard silicone rubber keypads that will fit into their design, unfortunately finding one with the correct size, shape and feel is very difficult. Advancing technology has brought the cost of custom silicone rubber keypads down significantly.

Design engineers don't like being stuck with just square or rectangular buttons when designing their custom silicone rubber keypads. As designers experiment with different shapes and colors they will try to find the most attractive look for their end customers for maximum sales.

Sometimes "odd" shaped silicone rubber buttons are designed so that they can fit in certain areas. It is possible that a given case may fit a triangle shape but not a more traditional rectangle or square shaped silicone button.

Custom silicone rubber keypads can be made in a wide variety of colors. Instead of just having a black silicone keypad you can pick not only the base color of the keypad but colors of each button. Once you have picked the color or colors of each of the buttons you can also pick different colors for the graphics and symbols to be printed onto each of the silicone buttons.

If differentiation between buttons is important in your custom silicone rubber keypad then try using different colors for buttons on your keypad. A good example is using a red button for an emergency function and gray for the rest of the silicone buttons. The button that sticks out the most is the red emergency button, using the same color on all of the buttons would not allow a single button to stand out from the rest.

For symbols, lettering or other markings on silicone rubber keypads the two common methods are screen printing (silk screening) or laser etching. Screen printing is less expensive but the printing tends to wear off faster over time when compared to laser etching. Screen printing is the process of creating a custom screen and then applying ink to the screen when then is pressed against the silicone keypad leaving a layer of ink in the shape of the desired symbol.

Even though laser etching has a slightly more expensive setup charge it is the preferred method for creating artwork, symbols and lettering on silicone rubber keypads. The two major reasons for this are: laser etching allows you to create printing that can be lit up at night time and the laser etching lasts longer than screen printing.

To help screen printing or laser etching last longer a protective coating is normally applied. The most commonly used option is PU (polyurethane) spray coating, it is also the least expensive option. Customers specify a matte or glossy finish of polyurethane (PU) coating which is sprayed on and provides a layer of protection to increase longevity of printing on a custom silicone rubber keypad. Low cost and effectiveness has made polyurethane spay coating a very popular option. If you do not mind a glossy thicker looking silicone rubber keypad then an epoxy coating is worth consideration. Epoxy coating is the most durable and provides the maximum protection for your silicone rubber keypads.

There are many options to consider when designing a custom silicone rubber keypad. If you are a designer and are new to silicone rubber designs make sure you contact a custom silicone rubber keypad manufacturer for assistance. Most of the manufactures are knowledgeable and are happy to help, some even have free sample silicone rubber keypads they will send you to help you select the right look and feel for your design.

Solar now replaces black gold

Petroleum and coal are standard sources of energy and have been the important source of energy generation since the last few centuries. But recently due to excessive and irrational use, these sources are on the edge of becoming tired as their quantity in the earth crust is limited . Without these sources our world could come at a halt if solar photovoltaics had not come to our rescue.

Solar photovoltaics are the modern alternative to conventional sources like coal and petroleum. Photoelectric effect given by elements like silicon implying that when light energy is incident on the surface of silicon, electrons are emitted and therefore current is generated. This principle is utilized in solar photovoltaics. Thin films of silicon are made which are referred to as photovoltaic cells and they are connected in required number in series to produce desired quantity of electricity.

The usage of solar photovoltaics is encouraged due to more reasons than one world over. It's a fact that mineral oil takes millions of years to form and nothing can be done to pace up the method along with it, mineral oil is in a limited quantity is also a proven fact. And so these sources are non renewable. On the other hand as sun being the power source behind solar photovoltaics system, it is a replenish-able energy source. Solar photovoltaics are now replacing the use black gold in many sectors due to its straightforward availability in the market and guaranteed paybacks in an exceedingly short time.

After installation solar photovoltaics provide clean and eco friendly energy that has no undesirable effect on the environment unlike the conventional sources which produce green house gases and therefore giving a push to global temperature increases and other environmental hazards like depletion of ozone layer or unsteadiness in nature for example. It doesn't leave any deadly residue aswell. The present generation if evolves with solar photovoltaics it will lead to fall in the pollution levels in the atmosphere. So even if we are facing the depletion of petroleum and coal, the world will not come to a dead stop.

The price of installation of these solar photovoltaics isn't much costly and with aid from it you are able to save energy and cut the price of your electricity bills. The requirement of energy in heating, cooling etc can be met with these solar photovoltaics. Almost all of the household gadgets like geysers, television sets, mixer grinder and lots more can be run utilizing the energy produced here. These days each power source includes a heavy price tag while energy produced using solar photovoltaics come free!

Our closest star, the sun is without doubt a star and a life saver. It is an endless source of energy and if this is utilised in the proper way all our energy crises can be explained and we shall never have to look at any other energy source to meet our wants. Solar photovoltaic is our new and easy road to clean, free and eco friendly energy and healthy and green strategy for living.
