Ukuphila kuhlelwe zingenza abantu bagcwale comfortable.Naturally, kuhlelwe PCB design futhi ekholisa ngokwengeziwe, futhi unjiniyela isakhiwo kungaba ephumayo kancane.
Inombolo ungqimba PCB ibhodi ngokuvamile awuxhomekile kusengaphambili, sihlelwe by ebhodini unjiniyela sika oluphelele, futhi inani eliphelele izingqimba siqukethe inani isignali izingqimba futhi inani Izendlalelo kwamandla.
1. Ukuhlela ugesi kanye nenombolo stratum
Isibalo zamatshe okuphakela amandla ikakhulukazi kunqunywa inani izinhlobo ugesi, ukusatshalaliswa, umthwalo umthamo, ukusebenza Inkomba ibhodi elilodwa futhi izindleko board.The kulungiselelwa eyodwa indiza amandla kudingeka sanelise imibandela emibili: amandla supply akuyona interlaced.Avoid ezibalulekile cross-ingxenye izingqimba eduze.
Ilungiselelo inombolo ungqimba phansi kufanele sinake la maphuzu alandelayo: amadivaysi main kufanele ibe indiza phansi kuqhathaniswa ngokuphelele ubuso ungqimba yesibili; amasignali Okubalulekile ezifana ngesivinini, imvamisa high, iwashi, etc.Main ugesi futhi indiza phansi elihlangana Friend, ukunciphisa impedance amandla indiza nokunye.
2. esiginali inombolo ungqimba ukuhlela
iziteshi Wiring ngokuvamile zezici ezibalulekile ukucacisa inombolo isignali layers.It kubalulekile ukwazi ukuthi kukhona BGA ezijulile futhi isixhumi ebhodini, nokudepha BGA ukujula PIN izikhala BGA kukhona ukhiye ukucacisa inombolo BGA line.For Ngokwesibonelo, BGA ka 1.0mm akwazi ukuwela imigqa emibili evamile, 0.8mm umgodi BGA kwesiphambano kuphela kudlule umugqa owodwa, futhi inani umugqa phakathi kwemigqa emibili kakhulu different.The isixhumi ikakhulu uyazicabangela ukujula salo, esiwulwazi pair of umehluko imigqa phakathi izimbobo ezimbili.
Okwesibili, kumelwe sicabangele wiring ibhodi ngesivinini isignali siteshi, ngoba lapho isignali ngesivinini ukucutshungulwa nezidingo izimo Ngaphezu kwalokho, kudingeka ucabangele a stub, ukuhlukanisa imigqa, yizinto ezifana indiza inkomba, ngakho udinga ukuba abeke ukuze wiring isiteshi salo kwanele. 
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.
Ngaphambi kokuqala design PCB, kufanele wazi usayizi PCB: lokhu kuncike usayizi wesithombe sakho umkhiqizo, izingqimba PCB: izingqimba okwengeziwe, kulapho eziyinkimbinkimbi yokukhiqiza we PCB kuyoba, zogqinsi kakhulu PCB ine, eqolo kuzoba okwenza kube, KingSong PCB specilized ngokusemthethweni ekuhlinzekeni insizakalo PCB yokukhiqiza. Asikwazanga ukusekela ahlukahlukene ephrintiwe wesifunda ibhodi yokukhiqiza isevisi kusuka isendlalelo esisodwa aye engxenyeni 36 ukuhlangabezana PCB zakho ezihlukile requirements.When uqeda design layout, uthola ifayela Gerber, leli fayela izosetshenziswa yakho umakhi PCB , Yize kukhona abaningi izinkampani ezihlinzeka lawo masevisi, kepha singathanda ukuncoma King-PCB.COM.
