The system uses MSP430F149 do give priority to the controller, cooperate with FS4001 gas mass flow sensor complete the gas content test. The whole function circuit includes MCU module, ferroelectric storage module, clock module, keyboard module, LCD display module, USB communication circuit module unit (Ji Liming 2010). 

ASIC derotes application-specific integrated circuit, which combines several functional circuits in a imit IC. Digital IC is common for ASIC, though an IC containing analog circuits is also used. A variety of ASICs are applied to industry, business, and home use. 

The term thick film (T-F) technology is accepted to mean that field of microelectronics in which specially-formed pastes are applied and fired on to a ceramic substrate in a defined pattern and sequence to produce a set of individual components such as resistors and capacitors, or a complete functional circuit (19). Figure 11.3 shows a flow diagram of a standard thick film process.

Device A functional circuit, component, or network unit, such as a vacuum tube or transistor. 

The fimction of the substrate is to provide the base onto which thin-film circuits and/or thick-film circuits, which make up the electrical circuits, are fabricated and various multilayer films are deposited. In addition, the substrate provides the necessary mechanical support and rigidity needed to produce a reliable functional circuit. It must have adequate thermal management ability to ensure proper temperature operation, and it must possess a proper electrical insulation to withstand circuit voltages without breakdown. One can think of the substrate as the foimdation on which the circuit traces and components are mounted and supported. Ceramic materials are often used for thin- and thick-film applications, because ceramics have high thermal conductivity, good chemical stability, and are also resistant to thermal and mechanical shock [4]. 

Cell-phones, iPODs, digitial cameras, laptops and desktop computers, DVDs, and indeed all electronic equipment in our world have one thing in common They each contain an electronic assembly composed of integrated circuits and discrete components soldered to a printed wiring board (PWB) to create an electrically functional circuit. 

Diagrams are the main aids to repair. For fault location the most essential information is that concerning functional structure, i.e. how the components are connected to perform their required function. Circuit diagrams are often criticized on the basis of bad presentation due to this, national standards were developed to specify the requirements for an efficient diagram.
