Highleap e hlahloba lintlha tsa tlhahiso ho lekola jiometri ea boto, sebopeho sa lera, litlhoko tsa ho phunya, qetello ea bokaholimo le lits'ebetso life kapa life tse ikhethang. Likhetho tse latelang li khetholla litlhoko tsa mantlha tseo u lokelang ho li hlalosa ha u fumana PCB ea lera le tšeletseng.

Hobaneng Lifaele tsa Gerber li le Bohlokoa bakeng sa Khoutu ea PCB ea Mekhahlelo e 6

Lifaele tsa Gerber li hlalosa mekhoa ea koporo, maske ea solder, legend le mekhahlelo e meng ea tlhahiso e hlokahalang ho utloisisa sebopeho sa 'mele sa boto. Lifaele tsa drill tsa NC li totobatsa libaka le boholo ba masoba, ha tlhaiso-leseling ea stackup le litšoantšo tsa tlhahiso li hlalosa litlhoko tse ling tsa kaho le ts'ebetso. Hammoho, lifaele tsena li lumella sehlopha sa tlhahiso ho lekola litlhoko tsa 'nete tsa tlhahiso ea boto.

Mohlala, PCB ea mekhahlelo e tšeletseng e ka ba le moralo o tloaelehileng le masoba a phunyeletsoeng, ha moralo o mong oa boholo bo tšoanang o ka kenyelletsa menoana e melelele le e mekhutšoanyane ea khauta, libaka tsa ho kopana tse arotsoeng ka likarolo, libaka tse laoloang ka botebo, libaka tse foufetseng, tšepe e ka lehlakoreng, li-vias tse foufetseng kapa tse patiloeng, kapa mamello e khethehileng ea litekanyo. Likarolo tsena ha li hlalosoe ka botlalo kamehla ke palo ea lera kapa tlhaloso e khutšoanyane e ngotsoeng. Tse ling li hloka litšoantšo tse ling, litlhaloso tsa botebo, lintlha tsa ho betla kapa lintlha tsa tlhahiso.

Ntle le difaele le ditlhaloso tse amehang, dintlha tsa bohlokwa di ka nna tsa ba siyo sebokeng sa khotheishene. Theko e thehilweng feela hodima "6 layer PCB," boholo le bongata ba boto di kanna tsa se ke tsa ikarabella bakeng sa ditshebetso tse ikgethang, ditlhoko tsa tlhahlobo kapa dithibelo tsa tlhahiso. Ho hlahloba moralo wa nnete ho thusa ho fokotsa ditheko tse sa fellang, ho hlakisa kgafetsa le diphetoho tse ka qojwang kamora hore odara e bewe.

Lihlopha tsena li thusa ho hlalosa boholo ba projeke; ha li bolele hore motsoako o mong le o mong ke moaho o tloaelehileng. Lisebelisoa tse ikhethileng, meaho ea khauta, likarolo tse laoloang botebo, tšepe e ka lehlakoreng le litlhoko tse ling tse seng tsa maemo li tlameha ho hlahlojoa khahlanong le bokhoni ba 'nete ba moralo le tlhahiso pele ho amoheloa khotheishene le odara.

Likabelo tsa mekhahlelo li lokela ho bonts'a tsela ea lipontšo, lifofane tsa litšupiso, kabo ea matla le litlhoko tsa lipotoloho tse bonolo. Matšoao a lebelo le phahameng a hloka litsela tse nepahetseng tsa ho khutla, ha mekhahlelo e fumanehang ea litsela e tlameha ho amohela pinout ea sesebelisoa le bongata ba khokahano. Ha ho na stackup e le 'ngoe ea mekhahlelo e tšeletseng e loketseng moralo o mong le o mong.

Ha o kopa khotheishene, fana ka boima ba koporo bakeng sa lera ka leng, botenya ba dielectric, botenya ba boto bo fedileng le ditlhoko dife kapa dife tse laolwang tsa impedance. Bakeng sa mesaletsa e laolwang ke impedance kapa dipara tse fapaneng, totobatsa boleng ba sepheo, mamello le mesaletsa ya matshwao e amehang. Jeometri ya trace, thepa ya thepa le tokisetso ya dielectric di hloka ho lekolwa mmoho.

Moralo o loketseng oa ho bokellana ha li-PCB o tlameha ho ikarabella bakeng sa likabelo tsa lera, sebaka sa dielectric, lifofane tsa litšupiso le lipheo tsa impedance. Bakeng sa moralo o seng o ntse o le teng, fana ka lera le lokollotsoeng ho fapana le ho itšetleha ka tlhophiso e akaretsang ea lera tse tšeletseng.
