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. ‘N Koperplaatplaat word gedruk en uit die etskring geëts.

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. Ons moet dus gate in die bord maak sodat die penne deur die bord na die ander kant kan gaan, sodat die penne van die dele aan die ander kant vasgesweis word.

Because of this, the front and back sides of such a PCB are called part surfaces and weld surfaces respectively. ‘N Dubbellaagbord kan gesien word as twee enkellaags planke wat aan mekaar vasgeplak is, met elektroniese komponente en bedrading aan weerskante van die bord. Sometimes it is necessary to connect a single wire from one side to the other side of the board through a guide hole. Gidingsgate is klein gaatjies in die PCB gevul of bedek met metaal wat aan beide kante met drade verbind kan word. 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. Die probleem om lyne tussen lae te verbind, kom ook voor op meerlaags PCBS, wat ook deur geleidingsgate bereik kan word.

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. Blinde gate verbind verskeie lae interne PCBS met oppervlak PCBS sonder om die hele bord binne te dring. Begrawe gate is slegs aan die interne PCB gekoppel, sodat lig nie van die oppervlak af sigbaar is nie. In ‘n meerlaagse PCB is die hele laag direk verbind met die gronddraad en die kragtoevoer.

So we classify each layer as signal layer, power layer or ground layer. As die onderdele op die PCB verskillende kragtoevoer benodig, het hulle gewoonlik meer as twee krag- en draadlae. The more PCB layers you use, the higher the cost. Of course, using more layers of PCBS helps to provide signal stability.
