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. Ny takelaka vita amin’ny varahina vita amin’ny varahina dia vita pirinty ary voasokitra avy ao amin’ny faribolana.

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. Noho izany dia mila manisy lavaka ao amin’ny solaitrabe isika mba hahafahan’ny tsimatra mandalo ilay tabilao mankany amin’ny ilany hafa, noho izany ny pin’ny faritra dia miraikitra amin’ny ilany hafa.

Because of this, the front and back sides of such a PCB are called part surfaces and weld surfaces respectively. Ny tabilao misy sosona roa sosona dia azo jerena ho toy ny zana-kazo roa sosona mifatotra, miaraka amin’ireo singa elektronika sy tariby eo amin’ny lafiny roa amin’ny solaitrabe. Sometimes it is necessary to connect a single wire from one side to the other side of the board through a guide hole. Ny lavaka torolàlana dia lavaka kely ao amin’ny PCB feno na mifono vy izay azo ampifandraisina amin’ny tariby amin’ny andaniny roa. 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. Ny olan’ny fampifandraisana ireo andalana eo anelanelan’ny sosona dia sendra ny PCBS marobe ihany koa izay azo tratrarina amin’ny alàlan’ny lavaka fitarihana.

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. Ny lavaka jamba dia mampifandray sosona maromaro an’ny PCBS ao anaty PCBS ambonin’ny tany nefa tsy tafiditra ao anatin’ny tabilao iray manontolo. Ny lavaka milevina dia mifamatotra amin’ny PCB ao anatiny ihany, ka ny hazavana dia tsy tazana avy eny amboniny. Ao amin’ny PCB multilayer, ny sosona iray manontolo dia mifandray mivantana amin’ny tariby amin’ny tany sy ny herinaratra.

So we classify each layer as signal layer, power layer or ground layer. Raha toa ka mitaky famatsiana herinaratra samihafa ireo faritra ao amin’ny PCB dia mazàna manana sosona herinaratra sy tariby mihoatra ny roa izy ireo. The more PCB layers you use, the higher the cost. Of course, using more layers of PCBS helps to provide signal stability.
