What is the assembly of instrumentation?

Instrumentation assembly is strictly in accordance with the design requirements, the relevant electronic components, parts, the whole piece of mounting disk on the specified position, and composed of a certain function of the instrumentation process. It is divided into electrical assembly and mechanical assembly of two parts. Electrical assembly is from the electrical performance, according to the layout of components and parts, through the lead will be connected to them; mechanical assembly is based on the technical requirements of the product design, the parts according to the positional accuracy, surface matching accuracy and movement accuracy assembly. The main contents of instrumentation assembly include the division of instrumentation unit, the layout of components, the processing of components, wire ties and parts, the installation and welding of various components, the assembly of parts and components, and the assembly of assembled parts and the total assembly of the whole machine. In the assembly process according to the size of the assembly unit, the complexity and characteristics of the different, can be divided into different levels of instrumentation assembly, assembly level is as follows. (1) Component level assembly. It is the lowest assembly level, usually refers to the assembly of circuit components and integrated circuits, which is characterized by the inseparable structure. (2) Plug-in level assembly. Used to assemble and interconnect the first level of components, such as printed circuit boards or plug-ins containing components. (3) Chassis level or plug-in box level assembly. Used to mount and interconnect plug-in or printed circuit board components of the second level of assembly. (4) System level assembly. Mainly through the cable and connector interconnection of the first two levels of assembly, and power feeds to form an independent instrument or device with a certain function. For the system level, the equipment may not be in the same place, need to use the output line and other ways to connect. For example, zirconia oxygen content analyzer, primary and secondary instrumentation is connected with control lines, compensation lines to form a system. (5) assembly link on the assembly of the main production process. It is good or bad directly determine the quality of the product and work efficiency, is a very important part of the whole machine assembly.
