853-049542-173 PCB電路板是電子工業(yè)的重要部件之一。幾乎每種電子設(shè)備，小到電子手表、計(jì)算器，大到計(jì)算機(jī)通信電子設(shè)備、軍用武器系統(tǒng)，只要有集成電路等電子元件，853-049542-173 PCB電路板為了使各個(gè)元件之間的電氣互連，都要使用印制板。印制線路板由絕緣底板、連接導(dǎo)線和裝配焊接電子元件的焊盤組成，853-049542-173 PCB電路板具有導(dǎo)電線路和絕緣底板的雙重作用。它可以代替復(fù)雜的布線，實(shí)現(xiàn)電路中各元件之間的電氣連接，不僅簡(jiǎn)化了電子產(chǎn)品的裝配、焊接工作，減少傳統(tǒng)方式下的接線工作量，大大減輕工人的勞動(dòng)強(qiáng)度;而且縮小了整機(jī)體積，降低產(chǎn)品成本，提高電子設(shè)備的質(zhì)量和可靠性。印制線路板具有良好的產(chǎn)品一致性，它可以采用標(biāo)準(zhǔn)化設(shè)計(jì)，有利于在生產(chǎn)過(guò)程中實(shí)現(xiàn)機(jī)械化和自動(dòng)化。同時(shí)，整塊經(jīng)過(guò)裝配調(diào)試的印制線路板可以作為一個(gè)獨(dú)立的備件，便于整機(jī)產(chǎn)品的互換與維修。目前，印制線路板已經(jīng)極其廣泛地應(yīng)用在電子產(chǎn)品的生產(chǎn)制造中。[2]印制線路板最早使用的是紙基覆銅印制板。853-049542-173 PCB電路板自半導(dǎo)體晶體管于20世紀(jì)50年代出現(xiàn)以來(lái)，對(duì)印制板的需求量急劇上升。特別是集成電路的迅速發(fā)展及廣泛應(yīng)用，使電子設(shè)備的體積越來(lái)越小，電路布線密度和難度越來(lái)越大，這就要求印制板要不斷更新。目前印制板的品種已從單面板發(fā)展到雙面板、多層板和撓性板;結(jié)構(gòu)和質(zhì)量也已發(fā)展到超高密度、微型化和高可靠性程度;新的設(shè)計(jì)方法、設(shè)計(jì)用品和制板材料、制板工藝不斷涌現(xiàn)。近年來(lái)，各種計(jì)算機(jī)輔助設(shè)計(jì)(CAD)印制線路板的應(yīng)用軟件已經(jīng)在行業(yè)內(nèi)普及與推廣，在專門化的印制板生產(chǎn)廠家中，機(jī)械化、自動(dòng)化生產(chǎn)已經(jīng)完全取代了手工操作。

【英文介紹】
853-049542-173 PCB circuit board is one of the important components of the electronics industry. Almost every electronic equipment, small to electronic watches, calculators, large to computer communication electronic equipment, military weapon systems, as long as there are electronic components such as integrated circuits, 853-049542-173 PCB circuit board in order to make the electrical interconnection between the various components, must use printed boards. The printed circuit board is composed of an insulating base plate, a connecting wire and a welding pad for assembling welded electronic components. The 853-049542-173 PCB circuit board has the dual role of conductive line and insulating base plate. It can replace the complex wiring, realize the electrical connection between the components in the circuit, not only simplifies the assembly of electronic products, welding work, reduce the traditional way of wiring workload, greatly reduce the labor intensity of workers; It also reduces the volume of the whole machine, reduces the cost of the product, and improves the quality and reliability of the electronic equipment. The printed circuit board has good product consistency, and it can adopt standardized design, which is conducive to mechanization and automation in the production process. At the same time, the whole assembled and adjusted printed circuit board can be used as an independent spare part, which is convenient for the exchange and maintenance of the whole machine product. At present, printed circuit boards have been extremely widely used in the manufacturing of electronic products. [2] The earliest use of printed circuit boards is paper-based copper-coated printed boards. 853-049542-173 PCB Circuit board Since the advent of semiconductor transistors in the 1950s, the demand for printed boards has risen dramatically. In particular, the rapid development and wide application of integrated circuits have made the size of electronic devices smaller and smaller, and the circuit wiring density and difficulty are increasing, which requires printed boards to be constantly updated. At present, the varieties of printed boards have developed from single panels to double panels, multi-layer boards and flexible boards; The structure and quality have also been developed to ultra-high density, miniaturization and high reliability; New design methods, design supplies and board making materials, board making technology continue to emerge. In recent years, a variety of computer aided design (CAD) printed circuit board application software has been popularized and promoted in the industry, in specialized printed board manufacturers, mechanized, automated production has completely replaced manual operation.
