Computer engineering has evolved by leaps and bounds. Advancements in this field are now well-entrenched in modern lifestyles.
If people go through all the electronic hardware manufactured all around the world, they will see that among the significant technological common denominators is the presence of semiconductors and circuit boards. A lot of people don’t know this, but without these two elements, the world won’t be enjoying the most integral and ubiquitous technologies, such as computers and mobile phones.

Semiconductors are an integral part of circuits. They are usually crystalline and amorphous, which allows them to conduct electricity. They have a higher resistance than most materials, except those of insulators. They are the opposite of metals, whose resistance tends to rise as the temperature goes up. Semiconductors’ resistance goes down with an increase in temperature. They can be found in microprocessors and circuit boards.

Circuit boards, or printed circuit boards, connect electronic equipment to each other. A lot of today’s gadgets have circuit boards – computers, mobile phones, TVs, radios, amplifiers, MP3 players, radars, sonars, laboratory equipment, and more. Not all circuit boards are the same though. How they are manufactured is dependent on their purpose, and the dimensions of the electronic device into which they’ll be installed.
