英文题目AbstractPCB,also known as printed circuit board in Chinese,can be called printed circuitboard,it can be said to be one of the most critical electronic components in anelectronic product.It supports all the electronic components of an electronic product,so it can also be said to play an important role in the electrical connection ofelectronic components.It is called "printed"circuit board because its fabricationprocess is made on the substrate using electronic printing.PCB has many unique advantages,that is it can attract more and more widelyused and reasons,the PCB can be made into density is very high,at the same time italso is very reliable,not only that,it also can be used as people's needs for differentdesigns,as well as PCB production can quantitatively,to test after the finishedproducts,also can use for different PCB assembly,etc.Among them,printed circuitboard has been able to follow the continuous improvement of integrated circuitintegration and the progress of installation technology so as to develop accordingly.Through a number of regular inspection of the finished products,regular testing of thefinished products and the prevention of product aging test and other technical means,can ensure that PCB long-term(generally 20 years)and reliable work.Not only that,PCB can also make the system small,lightweight,high-speed signal transmission.As one of the most basic components of many electronic products,the profoundchanges in the downstream consumer market of PCB will undoubtedly promote thedevelopment trajectory of the PCB industry.Industry professionals predict that inthree to five years'time,5G communication function can become the first enginedriving the growth of PCB industry,which can not only surpass today's intelligentterminals,but also surpass the two major application markets of automotiveelectronics.Keywords:Printed circuit boards;High density;Circuit integration;Intelligentterminal
