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. Bakarna osnovna ploča odštampana je i iscrtana iz kruga za nagrizanje.

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. Zato moramo napraviti rupe na ploči tako da igle mogu proći kroz ploču na drugu stranu, tako da su igle dijelova zavarene na drugu stranu.

Because of this, the front and back sides of such a PCB are called part surfaces and weld surfaces respectively. Dvoslojna ploča može se vidjeti kao dvije jednoslojne ploče zalijepljene zajedno, s elektroničkim komponentama i ožičenjima s obje strane ploče. Sometimes it is necessary to connect a single wire from one side to the other side of the board through a guide hole. Rupe za vođenje su male rupe na PCB -u ispunjene ili presvučene metalom koje se mogu spojiti na žice s obje strane. 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. Problem povezivanja vodova između slojeva također se susreće na višeslojnom PCBS-u, što se može postići i kroz rupe za vođenje.

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. Slepe rupe povezuju nekoliko slojeva unutrašnjeg PCBS -a sa površinskim PCBS -om bez prodiranja kroz celu ploču. Ukopane rupe povezane su samo s unutarnjom PCB -om, tako da se svjetlost ne vidi s površine. U višeslojnoj PCB -i, cijeli sloj je direktno povezan sa žicom za uzemljenje i napajanjem.

So we classify each layer as signal layer, power layer or ground layer. Ako dijelovi na PCB -u zahtijevaju različita napajanja, obično imaju više od dva sloja napajanja i žice. The more PCB layers you use, the higher the cost. Of course, using more layers of PCBS helps to provide signal stability.
