Integrated circuits are referred to as chips. Such electronic components as transistors, diodes, resistors and capacitors that were compact are manufactured from a piece of semiconductor material. They are widely used in areas like operating controlling and producing the products around us are connected with these things. After the circuits have been developed, they have become ubiquitous. Now they have been inextricable in digital cameras, cell phones, and computers. To put it differently, modern communication, traffic systems, telecommunication and technology are based on the circuits. The technology is now a part of work and our life. The creation of circuits is a revolution in the industry.
According to their use, they can be sorted into two kinds the circuits as well as the analog circuits. the top chip broker on the planet can be classified into types. With the development of digitization, the today is the circuits that are electronic and they can be seen in frequency synthesizer, digital counters and computers. Packages of these circuits vary in accordance with their shapes and sizes. The most frequently seen is the dual type; this type has 16 pins such as 8, 24 and so on. One of its advantages is that it isn’t hard to use with just to place on the slots. Integrated circuits are components that were vulnerable some attentions have to be taken into consideration when to use them. The most significant is that it had better be kept out of humidity and high temperature.
Nowadays, with the advent of scale of line was reduced and the operation has gotten high efficient and much better also. The circuit market has become a pillar industry from now on and our life will be filled with colour. The IC’s also very delicate and has to be protected which is another reason. Failure analysis of IC’s needs access. One of the steps while doing the analysis is to extricate the circuits of attention out of their covering. This procedure is named integrated circuit encapsulation. We prefer using failure analysis methods which keep the structure in tact with testing processes that are nondestructive, sometimes there. There are a number of ways and based on the type of encapsulation we would like which part we will need to analyze and to execute. Three ways for an integrated circuit is plasma etching, heating, and chemical etching. Chemical etching involves applying an acidic substance to the case. As may be guessed, this is a procedure which requires careful use of the material. Either sulphuric or nitric acid may be used for this purpose.
