It is not difficult to learn पीसीबी 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. एक तांबेदार आधार प्लेट छापिएको छ र नक़्कस सर्किट को बाहिर etched छ।

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. त्यसोभए हामी बोर्ड मा प्वाल बनाउन को लागी आवश्यक छ कि पिनहरु को माध्यम बाट बोर्ड को अर्को पट्टि जान सक्छ, त्यसैले भागहरु को पिन अर्को तिर वेल्डेड छन्।

Because of this, the front and back sides of such a PCB are called part surfaces and weld surfaces respectively. एक डबल-लेयर बोर्ड दुई एकल-लेयर बोर्डहरु सँगै चिपकेका रूपमा देख्न सकिन्छ, इलेक्ट्रोनिक घटक र बोर्ड को दुबै छेउमा तारहरु संग। Sometimes it is necessary to connect a single wire from one side to the other side of the board through a guide hole. गाइड प्वाल पीसीबी भरीएको वा धातु संग लेपित छ कि दुबै पक्ष मा तार संग जोडिएको हुन सक्छ मा सानो प्वाल हो। 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. परतहरु को बीच लाइनहरु लाई जोड्ने समस्या को भी बहु परत PCBS मा सामना गरीएको छ, जो पनी गाइड छेद को माध्यम बाट हासिल गर्न सकिन्छ।

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. ब्लाइन्ड प्वालहरु सम्पूर्ण बोर्ड मर्मज्ञ बिना सतह पीसीबीएस आन्तरिक PCBS को धेरै तहहरु लाई जोड्नुहोस्। गाडिएको प्वाल मात्र आन्तरिक पीसीबी संग जोडिएको छ, त्यसैले प्रकाश सतह बाट देखिने छैन। एक multilayer पीसीबी मा, पूरै तह सीधै जमीन तार र बिजुली आपूर्ति संग जोडिएको छ।

So we classify each layer as signal layer, power layer or ground layer. यदि पीसीबी मा भागहरु बिभिन्न बिजुली आपूर्ति को आवश्यकता छ, उनीहरु लाई सामान्यतया दुई भन्दा बढी शक्ति र तार तहहरु छन्। The more PCB layers you use, the higher the cost. Of course, using more layers of PCBS helps to provide signal stability.
