Mobile phones are electronic devices that enhance communication and as norm electronic devices incorporate signals send and received by use of electric charges. The flow of electricity in any device results to some heat that majorly results from leakages of charges. These productions of heat calls for the use of rubber in making the sensitive parts of electronic devices, mobile phones included. The most commonly used rubber is silicon due to the fact that it resists both flame and water in addition to its softness. Rubber is a non-conductor of electricity and is preferred to plastic as an insulator. When silicon rubber is subjected to heat it first thickens resulting to a shrinking and if the heat is not that high which always the case in electronic devices the rubber would not melt. Despite the fact that rubber might be more expensive and involve a complex process of fixing, its benefits make it a common feature in mobile phones.

Main parts of a mobile phone
The major parts of a mobile phone include:
When a mobile phone is put apart, it becomes easier to notice the major parts that it contains. This includes: keypad, ear-piece, microphone, menu dial, camera lens, liquid crystal display, an antennae, speaker and battery. The inner parts of the mobile phone include the circuit board, which consists of three rooms; the analog to digital and the digital to analog conversion chips room, the digital signal processor, and lastly the microprocessor.
A mobile phone keypad is consisted of the alphanumeric keys that serve very useful purposes. The cell phone keyboard is made up of numbers and letter buttons that are used for dialing, typing and texting. The keypad will also be constituted of the # and * which are keys with special functions.
Mobile phones have an ear piece which is localized near the top of the mobile device. The ear piece serves the roles of a speaker and it helps the user to clearly hear well the other side of the conversation that is taking place. They are subjected to faults that can be easily diagnosed and rectified.
Every mobile has a microphone piece which is locate at the bottom of its design. The microphone piece is used to pick the volume from the speaker and do a transmission to the person listening on the further end of mobile line.
Most of the mobile phones keypads have a menu dial that is used to scroll down all the phone options and the address book. The steps in menu dial goes this way; you goes to the SIM menu, select the “ call” option, and then press ok.
Mobile phones have camera lens that are either situated at the top front or at the back of the device. The camera may be placed at the interior where the keypad and the menu dial is placed or also located on the phones exterior.
The display of a mobile device is the screen that shows the individual’s identity and the digits that re dialed by the mobile phone users. The display screen is different according to the type of the mobile phones and some are in a position to get a clear display of videos and websites.
A mobile phone antenna is a useful device that has the ability to transmit and receive signals that are in electromagnetic waves form. The antenna is in a position to receive and send mobile calls within the radius of transmission. This is enhanced by the ability of the antennae to transmit and receive the electromagnetic waves within the given frequencies. Introduction to the choice of the materials used
In order to manufacture the phone components there must be the materials and material science development. This is the knowledge that helps in making different cell phone parts, each of them performing specific functions and essential for the phone operations. The material used must be of different and specific properties for every part of the phone. This depends on the function to be performed by each part of the cell phone.
The phone components must be made of appropriate material. To choose the right material the appropriate characteristics are considered for the part to work efficiently. For instance, the case and key pad are considered to be solid thus offering maximum protection of the internal parts. This protects phone from the physical damage. On the other hand, the material must be light to increase portability of the appliance.
Different material for different parts
The case is usually made of metal or plastic this is to make it appropriate to overcome mechanical damage. The keypads of the phone are made of silicon rubber which is flexible in pressing the keys. These combinations must be light to reduce bulkiness of the phone. There is an important to choose the right metal or plastic in manufacturing of the case. Plastic is available and affordable and comes in a variety of shapes, sizes or colors.
The silicon is softer in comparing with plastic and rubber. The case is waterproof and does not stick to other materials making a smart cell phone case. The cases are fire and tear resistance and are easy to clean. Silicon is the best material in manufacturing of cases since it’s more like skin.
The antenna transmits and receives the signals between the phones. It is made of metal or fiberglass casing. They are generally fixed to an iron mask. For necessary coverage area of antenna, there is a case containing equipment such as amplifiers for providing transmission. Ceramics used in phones are made from Colton; an ore based on niobium and tantalum elements sources.
Cell phone uses liquid crystal displays, LCD screens that are type of flat-panel displays which consume less power. LCD screens compose of two inserted thin layers of glasses with liquid crystal. The liquid crystalline substances contains small amount of mercury which is toxic.
The best time-tested protectors of the phone in case of mechanical damage are the cork carbon fiber and fiberglass. Rubber, PC materials or nylon hydrocarbon polymer are used in manufacturing of covers.
In circuit boards which is the brain of the phone. This is essential electronic that power the cell phones. Its base is made from epoxy resin or fiberglass which composes its base in most cell phones.
Rubber cell phone skin; is rubberized cell phone ski which protects the phone body from any mechanical damages such as bumps and scratches. Most of the phone chargers, earphones and headphones are covered by rubber. Rubber is durable thus lust longer it is also bad conductor of electricity thus is used as insulator. Rubber provide cushion between the surfaces and contacts in charger. Rubber is elastic thus why they are used in manufacture of earphones and it is easy to clean. It offers comfort and compact fit in its applications. Rubber cases reduce vibrations.
As described above rubber has been used to make many of the mobile parts mostly due to its waterproof nature, durability, elasticity among many other advantages. The amount of rubber in each phone model increases each and every day as every plastic part from a previous model is replaced by rubber. This trend is therefore foreseen to continue up to the point where electronic devices will consist of pure functional units all of which are put together by a rubber material.
Innovation shows that an introduction of rubber circuit boards will accrue to achievement of technological requirements. To start with the phone will be foldable and therefore come along with some form of swag. Silicone rubber which is very strong an also stretchable can be use to replace the originally known plastic motherboard. Moreover, this motherboard will be resistant to breakage and thus it could be more durable
Phone cases have been designed using rubber; these cases are used to protect the inner parts of the phone. In an effort to eliminate the need for cases, a phone cover made up of purely rubber can be adopted. Since rubber is flexible and elastic it implies that it will resist breakage. The waterproof nature of rubber ensures maximum protection with the soft feeling associated with rubber guaranteeing comfort. The durability of these components could be increased by hardening rubber although this actually reduces the extent to which the material can be stretched, but at the same time improves the quality.
Mobile phones like any other electronic device are composed of many components that are incorporated and synchronized to perform its functions. These parts include those that deal with signals an others that receive and transform electric charges to bring about the receiving and sending of signals as well as converting them into and from sound waves. The making of these parts includes the use of rubber in most regions. Other materials can also be used in the place of rubber but so far none of these materials has been found to be better. Therefore, studies on the best materials that can be used in making mobile phone parts need to undertake in an effort to come up with new material as well as advancing the performance of the existing ones. This will help in satisfying the changes and requirements brought about by the technology.
