Is PCB design difficult?

It is not difficult to learn PCB 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. Kuprokovrita baza plato estas presita kaj gravurita el la akvaforta cirkvito.

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. Do ni bezonas fari truojn en la tabulo tiel ke la pingloj povas trairi la tabulon al la alia flanko, do la pingloj de la partoj estas velditaj al la alia flanko.

Because of this, the front and back sides of such a PCB are called part surfaces and weld surfaces respectively. Duoble-tavola tabulo videblas kiel du unu-tavolaj tabuloj kungluitaj, kun elektronikaj komponantoj kaj drataro ambaŭflanke de la tabulo. Sometimes it is necessary to connect a single wire from one side to the other side of the board through a guide hole. Gvidaj truoj estas malgrandaj truoj en la PCB plenigitaj aŭ tegitaj per metalo, kiuj povas esti konektitaj al dratoj ambaŭflanke. 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. La problemo de ligaj linioj inter tavoloj ankaŭ troviĝas ĉe plurtavola PCBS, kiu ankaŭ atingeblas per gvidaj truoj.

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. Blindaj truoj konektas plurajn tavolojn de interna PCBS al surfaca PCBS sen penetri la tutan tabulon. Entombigitaj truoj estas nur konektitaj al la interna PCB, do lumo ne videblas de la surfaco. En plurtavola PCB, la tuta tavolo estas rekte konektita al la tera drato kaj la nutrado.

So we classify each layer as signal layer, power layer or ground layer. Se la partoj sur la PCB bezonas malsamajn elektroprovizojn, ili kutime havas pli ol du potencajn kaj dratajn tavolojn. The more PCB layers you use, the higher the cost. Of course, using more layers of PCBS helps to provide signal stability.
