Do You Think Integrated Circuits Look like roaches
A typical IC has black body with many tiny silver legs, which makes it looks like a roach.
Definition: Integrated circuits (ICs) are a keystone of modern electronics. They are the heart and brains of most circuits. They are the ubiquitous little black “chips” you find on just about every circuit board. IC is a collection of electronic components: resistors, transistors, capacitors, etc. All of these stuffed into a tiny chip, and connected together to achieve a common goal. From below picture, you can see the guts of a IC.
You must know there are different types of packages of ICs. Such as BGA, QFP, DIP and so on, each of which has unique dimensions, mounting-types, and/or pin-counts. Then what’s the purpose of these packages? The reason is: IC die is the circuit in its smallest possible form, too small to solder or connect to. To make our job of connecting to the IC easier, we package the die. The IC package turns the delicate, tiny die, into the black chip we’re all familiar with.
Harm: ICs may contain small amounts of aluminum and arsenic. Lead may be contained in the solder that connects ICs to other electronic components. Inhaling or ingesting lead or arsenic can cause neurological damage, some cancers, and respiratory problems. If inhaled, aluminum dust or power also causes respiratory diseases and lung disorders.
Recycle: ICs use different types of metal wires to make electrical connections. These wires are made of metals such as gold, aluminum, copper, and lead. Precious metals can be extracted by recycling ICs using certain chemical processes which produce toxic byproducts in their own right. The bulk of ICs though consist of silicon and plastic and at the present time, are not considered cost-effective to recycle and are disposed of in landfills and similar waste facilities.
One of most complex and advanced ICs is a microprocessor. The microprocessor controls everything from computers and cellular phones to microwave ovens to robots to clothes dryers. For this reason, microprocessors and the ICs that contain them are called the heart and brains of most circuits.
