Mefuta e fapaneng ea li-PCB ke efe?
Li-unit tsa PCB li teng ka mefuta e mengata bakeng sa lits'ebetso tse fapaneng. Ho khetha moaho o nepahetseng bakeng sa sehlahisoa ho tla hloka hore moenjiniere a nahane ka tšebeliso e reriloeng ea sesebelisoa, boholo ba sona le lintlha tsa sona tsa matla. Hlahloba tse latelang ho utloisisa mefuta ea liboto tsa potoloho tse hatisitsoeng le hore na ke mefuta efe e loketseng boikitlaetso ba hau:
Li-PCB tse lehlakoreng le le leng: Ho etsoa ha PCB ho kenyelletsa ho etsa boto ea potoloho ho tsoa ho karolo e le 'ngoe ea substrate le lera le tšesaane la tšepe. Likarolo tsohle li soldered ka lehlakoreng le le leng.
Li-PCB tse mahlakoreng a mabeli: Mofuta oa PCB moo maqephe a tšepe a conductive a sebelisoang mahlakoreng ka bobeli a substrate.
Likoti li ka 'na tsa phunngoa bohareng ba boto ea potoloho ho lumella likhokahano ho matha mahlakoreng ka bobeli.
Multilayer PCBs: Bonyane ba li-PCB tse tharo tse mekato e 'meli tse koaletsoeng holim'a tse ling tse nang le likarolo tse 'maloa tsa ho kenya letsoho ho fokotsa phetiso ea mocheso. Likhomaretsi tse khethehileng li boloka letoto la li-PCB hammoho.
Li-PCB tse feto-fetohang: Liboto tsa potoloho tse hatisitsoeng tse bonts'ang li-substrates tse tenyetsehang ho thusa baenjiniere ho ikamahanya le libopeho tsa sehlahisoa se kopaneng. Theknoloji e ka 'na ea e-ba teng ka mokhoa oa ho haha mahlakore a le mong, a mabeli kapa a mangata.
Li-PCB tse Rigid: E thusa lihlahisoa tsa bareki tse bolokang sebopeho se tšoanang nakong eohle ea bophelo ba bona. Li-PCB tse thata li etsoa ka li-substrates tse thata tse hanang ho sotha.
Li-PCB tse thata-thata: Liboto tsa potoloho tse hatisitsoeng li sebelisa lisebelisoa tse thata le tse tenyetsehang. Litlhophiso tsena li lumella baetsi ba lihlahisoa ho boloka sebaka, kaha mekhoa ea ho hokahanya e thata le e tenyetsehang e ka kenyelletsoa botong e le 'ngoe ea potoloho.
Li-PCB tse tšehelitsoeng ke Aluminium: Mofuta oa PCB o nkelang sebaka sa aluminium substrate moo fiberglass e ka bang teng. E etselitsoe ho sebelisoa ka lisebelisoa tsa elektroniki tsa PCB tse matla joalo ka mabone a LED.
Li-PCB tsa maqhubu a phahameng: Boto ea potoloho e etselitsoe ho romela mats'oao a matla joalo ka 2 GHz.
Li-PCB li entsoe ka eng?
Ts'ebetso ea ho etsa PCB e shebahala e fapane ho latela sepheo se reriloeng sa yuniti le hore na ho hlokahala matla a makae ho etsa hore sesebelisoa sa elektroniki se sebetse. Pele u khetha lisebelisoa tsa kopano ea boto ea potoloho, ke mohopolo o motle ho itloaetsa likarolo tse nne tsa mantlha tsa yuniti ea PCB:
Substrate: The foreime ea sebopeho sa boto ea potoloho - likarolo tsohle fasten holim'a sena.
Laminates: Lisebelisoa tse tšoarang likarolo tsohle tsa PCB hammoho.
Maske a solder: E lutse ka holim'a lifoile tsa koporo molemong oa ho itšehla thajana le ho sireletsa likhokahano ho tsoa ho likarolo tsa tikoloho.
Silkscreen: E tiisa maske a solder e le hore likarolo li ka ngoloa.
Leano ke eng?
Sets'oants'o sa schematic, kapa schematic diagram, ke sesupo sa likarolo tsa sistimi e sebelisang matšoao a sa bonahaleng, a hlakileng ho fapana le litšoantšo tsa nnete.
Ke lintho life tse ka tlisoang bakeng sa ts'ebeletso ea Moralo oa PCB?
Bakeng sa litaelo tsa tšebeletso ea PCB Layout, lintlha tse latelang li tla fanoa faeleng ea tlhahiso:
Lintlha tse felletseng tsa Gerber ho kenyelletsa lifaele tsa Drill (Likarolo tsa Potoloho, Mask layers, Silk layers, Outline, Drill layers, Paste layers)
