Nolosha A qorsheeyay ka dhigi kara dadka dareemaan comfortable.Naturally, design ee PCB qorsheeyay sidoo kale waa wax qancin, iyo injineer khariidad noqon kartaa dariiq wareegsan yar.
Tirada lakabka of guddiga PCB guud ahaan aan ka go'an ka hor, waxaa la qorsheeyey by guddiga injineer ee dhamaystiran, iyo tirada guud ee layers ka kooban yahay tirada layers signal iyo tirada lakab oo korontada ah.
1. Qorsheynta ee korontada iyo lambarka stratum
Tirada layers of korontada waxaa badanaa lagu go'aamiyaa tirada noocyada kala duwan ee korontada, qaybinta, awoodda load, index waxqabadka guddiga hal iyo kharashka of goob board.The hal diyaarad awood u baahan yahay si ay u qanciso labada xaaladaha: korontada ma aha interlaced.Avoid muhiim cross-qaybta of layers xiga.
Goob Tirada daaha dhulka ka bixiyo in qodobbada soo socda fiiro: qalabka ugu muhiimsan waa in ay leeyihiin diyaarad dhulka xad dhameystiran ee wejiga of lakabka labaad, calaamadaha muhiimka ah sida xawaaraha sare, hirka sare, saacad, korontada etc.Main iyo diyaarad dhulka xigay dhagan, yareeyo impedance diyaarad xoogga iyo wixii la mid ah.
2. qorshaynta tiro lakabka Signal
channels Fiilooyinka sida caadiga ah waa arrimo muhiim ah in loo ogaado tirada layers.It signal muhiim ah in la ogaado in uu jiro BGA ah oo qoto dheer oo isku xira sabuuradda, oo si qoto dheer ee BGA iyo kala dheereynta PIN ee BGA waa muhiimka ah si loo ogaado tirada tusaale BGA line.For, BGA ee 1.0mm gudbi karaa laba xadhig sida caadiga ah, 0.8mm BGA cross godka keliya u gudbin kartaa mid ka mid ah line, iyo tirada line dhexeeya laba xadhig waa mid aad isku xira inta badan different.The tixgelinaysaa ay si qoto dheer, taas oo ah labo ka mid ah khadadka kala duwan oo u dhexeeya laba godad.
Second, waa in aan tixgelin doonna guddiga taararka-xawaaraha sare signal channel, maxaa yeelay, markaan shuruudaha-xawaaraha sare signal processing ah xaaladaha ku badan yahay, waxay u baahan yihiin si ay u eegaan kuunoqon ah, kala dheereynta line, arrimo ay ka mid yihiin diyaarad tixraaca, si aad u baahan tahay in la siiyo mudnaanta si ay channel taararka waa ku filan tahay. 
Finally, the bottleneck area is planned. After the basic layout is processed, it is necessary to focus on the narrow bottleneck area.Considering the difference line, sensitive signal line, special signal topology, etc., how many lines can be calculated in the bottleneck area, and how many layers can be used to make all the necessary lines pass through this area.
Considering the above two points,basically not appear to go some parts of the line, some people say: pcb design is like a high-rise building building process, the layout of the wiring layer is one of the design drawings, planning well, the wiring naturally It can be done.
Ka hor inta aadan bilaabin design PCB ah, waa in aad ogtahay size PCB: this ku xiran size wax soo saarka aad, layers PCB: lakabyada ka badan, wax soo saarka ka badan murugsan ee PCB waxay noqon doontaa, The more layers PCB uu leeyahay, ayaa in ka badan oo qaali ah waxa ay noqon doontaa si ay u sameeyo, KingSong PCB specilized bixinta adeegyada saarka PCB. Waxaan taageeri kara kala duwan adeegga saarka guddiga circuit ku daabacan ka lakabka hal ilaa 36 layers in ay la kulmaan aad PCB kala duwan requirements.When aad ku dhameysan design khariidad, waxaad ka heli file Gerber ah, file waxaa loo isticmaali doonaa by aad soo saaraha PCB , Inkasta oo ay jiraan dad badan shirkadaha in ay bixiyaan adeegyadan, laakiin waxaan jeclaan lahaa in aan ku talinaynaa King-PCB.COM.
