A shirya rayuwa iya sa mutane jin comfortable.Naturally, da shirya PCB zane ne ma mafi tabbatacce, kuma layout m iya zama ƙasa da detour.
A Layer yawan PCB jirgin ne kullum ba m a gaba, shi ne ya shirya da m ta da cikakken jirgin, kuma jimlar yawan yadudduka kunshi da yawan siginar yadudduka da kuma yawan yadudduka na da ikon samar.
1. Planning na samar da wutar lantarki da kuma sashen dutsen yawan
Yawan yadudduka na samar da wutar lantarki da aka yafi ƙaddara da yawan iri da samar da lantarki, da rarraba, load iya aiki, yi index of guda jirgin da kuma kudin da guda board.The saitin na da ikon jirgin sama bukatar ya gamsar da yanayi biyu: da ikon samar da shi ne ba interlaced.Avoid muhimmanci giciye-sashe na m yadudduka.
A Layer yawan saitin da ƙasa kamata kula da wadannan abubuwa: babban na'urorin ya kamata suna da gwada cikakken ƙasa jirgin sama a fuskar na biyu Layer. Muhimmi sakonni kamar high gudun, high mita, Agogon, etc.Main samar da lantarki da kuma ƙasa jirgin sama m hada guda biyu, rage ikon jirgin impedance da sauransu.
2. Signal Layer lambar shiryawa
wayoyi tashoshi yawanci muhimmanci abubuwan da sanin yawan siginar layers.It da muhimmanci a san ko akwai mai zurfi BGA da connector a kan jirgin, da kuma zurfin BGA da PIN jerawa na BGA ne key na ƙayyade yawan BGA line.For misali, BGA na 1.0mm iya haye biyu Lines kullum, 0.8mm BGA giciye rami iya kadai wuce daya line, da kuma yawan line tsakanin biyu Lines ne sosai different.The connector yafi gan ta zurfin, wanda shi ne na biyu na bambanci Lines tsakanin biyu ramukan.
Na biyu, dole ne mu yi la'akari da wayoyi hukumar high-gudun siginar tashar, saboda a lokacin da high-gudun siginar aiki da bukatun na yanayi ya fi, bukatar la'akari da wani stub, line jerawa, irin abubuwan da reference jirgin sama, don haka kana bukatar ka ba fifiko ta zuwa ga wayoyi tashar isa. 
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.
Kafin fara PCB zane, ya kamata ka san PCB size: wannan ya dogara da samfur naka size, PCB yadudduka: da more yadudduka, da more hadaddun da masana'antu na PCB zai kasance, The mafi yadudduka da PCB yana da, da mafi m shi zai zama zuwa tsirar da shi, KingSong PCB specilized a samar da PCB masana'antu da sabis. Mun iya tallafawa bambancin buga kewaye hukumar masana'antu da sabis na daga guda Layer to 36 yadudduka saduwa your daban-daban PCB requirements.When ka gama layout zane, ka samu wani Gerber fayil, wannan fayil za a iya amfani da your PCB manufacturer , Ko da yake akwai mutane da yawa kamfanonin da cewa samar da wadannan ayyuka, amma za mu so in bada shawara King-PCB.COM.
