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. Eng kupferfërmeg Basisplack gëtt gedréckt an aus dem Ätzkrees gezt.

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. Also musse mir Lächer am Board maachen sou datt d’Pins duerch de Board op déi aner Säit kënne goen, sou datt d’Pins vun den Deeler op déi aner Säit geschweißt ginn.

Because of this, the front and back sides of such a PCB are called part surfaces and weld surfaces respectively. En Duebelschicht Board ka gesi ginn als zwee Eenzel Schichten, déi zesumme gekollt sinn, mat elektronesche Komponenten a Kabelen op béide Säiten vum Board. Sometimes it is necessary to connect a single wire from one side to the other side of the board through a guide hole. Guide Lächer si kleng Lächer am PCB gefëllt oder mat Metall beschichtet, déi mat Drot op béide Säiten ugeschloss kënne ginn. 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. De Problem fir d’Linnen tëscht Schichten ze verbannen ass och op Multi-Layer PCBS opgetrueden, wat och duerch Guide Lächer erreecht ka ginn.

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. Blind Lächer verbannen verschidde Schichten intern PCBS mat Uewerfläch PCBS ouni de ganze Board ze penetréieren. Begruewe Lächer sinn nëmme mam internen PCB ugeschloss, sou datt d’Liicht net vun der Uewerfläch sichtbar ass. An engem Multilayer PCB ass déi ganz Schicht direkt mam Buedemdrot an der Energieversuergung verbonne.

So we classify each layer as signal layer, power layer or ground layer. Wann d’Deeler op der PCB verschidde Stroumversuergung erfuerderen, hu se normalerweis méi wéi zwou Kraaft- a Drotschichten. The more PCB layers you use, the higher the cost. Of course, using more layers of PCBS helps to provide signal stability.
