It is not difficult to learn Pkb design. The software is just a tool. If you have computer foundation, you can learn how to use PCB software in two weeks. The key is to understand the electronic circuit, small series of suggestions can buy some video tutorials on the Internet, their own spare time while learning while operating, fan Billion video is good, choose a set of suitable for their own.

Speaking of PCB, many friends will think that it can be seen everywhere around us, from all household appliances, all kinds of accessories in computers to all kinds of digital products, as long as electronic products almost all use PCB, so what is PCB on earth? A PCB is a PrintedCircuitBlock, which is a printed circuit board for electronic components to be placed on. Yon plak baz kwiv enprime ak grave soti nan kous la grave.

PCB can be divided into single, double and multilayer boards. All kinds of electronics are integrated into the PCB. On a basic single-layer PCB, the parts are concentrated on one side and the wires are concentrated on the other. Se konsa, nou bezwen fè twou nan tablo a pou ke broch yo ka ale nan tablo a lòt bò a, se konsa broch yo nan pati pyès sa yo soude sou lòt bò a.

Because of this, the front and back sides of such a PCB are called part surfaces and weld surfaces respectively. Yon tablo doub-kouch ka wè sa tankou de tablo sèl-kouch kole ansanm, ak konpozan elektwonik ak fil elektrik sou tou de bò tablo a. Sometimes it is necessary to connect a single wire from one side to the other side of the board through a guide hole. Twou Gid yo se ti twou nan PCB la plen oswa kouvwi ak metal ki ka konekte nan fil sou tou de bò yo. At present, many computer motherboards use 4 or even 6 layers OF PCB, while graphics cards generally use 6 layers of PCB. Many high-end graphics cards like nVIDIAGeForce4Ti series use 8 layers of PCB, which is the so-called multi-layer PCB. Pwoblèm lan nan konekte liy ant kouch tou rankontre sou milti-kouch PCBS, ki kapab tou reyalize nan twou gid.

Because of the multi-layer PCB, sometimes the guide holes do not need to penetrate the whole PCB. Such guide holes are called buried holes and blind holes because they only penetrate a few layers. Twou avèg konekte plizyè kouch entèn PCBS nan sifas PCBS san yo pa penetre tablo a tout antye. Twou antere yo sèlman konekte ak PCB entèn la, kidonk limyè a pa vizib nan sifas la. Nan yon PCB multikouch, kouch la tout antye dirèkteman konekte nan fil tè a ak ekipman pou pouvwa a.

So we classify each layer as signal layer, power layer or ground layer. Si pati pyès sa yo sou PCB la mande pou ekipman pou pouvwa diferan, yo anjeneral gen plis pase de kouch pouvwa ak fil. The more PCB layers you use, the higher the cost. Of course, using more layers of PCBS helps to provide signal stability.
