4 Layer ENIG FR4 Boima ba Koporo PCB
Koporo e Matla PCB
Liboto tse boima tsa koporo tsa PCB li ka etsoa feela ka ho kopanya mekhoa e 'meli e meholo, electroplating le etching.Ho fapana le PCBS tse ling, potoloho e entsoe ka lesela le tšesaane la foil ea koporo.
Li-PCB tse boima tsa koporo li entsoe ka laminated ka mokhoa o ts'oanang ka FR4 kapa lisebelisoa tse ling tse thehiloeng ho epoxy.Karolelano ea boima ba li-PCB tsa koporo e boima e ka ba li-ounces tse 4 (140μm), e leng karo-karolelano e molemo ho feta PCB e ’ngoe e tloaelehileng ea koporo.
Botenya bo eketsehileng ba koporo bo lumella boto ho tsamaisa maqhubu a phahameng, ho finyella kabo e ntle ea mocheso, le ho nolofalletsa ho fetoha ho rarahaneng sebakeng se lekanyelitsoeng.Melemo e meng e kenyelletsa matla a eketsehileng a mechine libakeng tsa li-connector, bokhoni ba ho etsa boholo ba lihlahisoa tse nyenyane ka ho kopanya litekanyo tse ngata sebakeng se le seng sa potoloho, le bokhoni ba ho sebelisa lisebelisoa tse khethehileng tse nang le kotsi e fokolang ea ho hlōleha ha potoloho.
Melemo ea Koporo e Boima PCB
Ho etsoa ha li-PCB tse boima tsa koporo ho kenyelletsa tšebeliso ea plating kapa etching, kaha e eketsa botenya ba PCB ea koporo maboteng a mahlakoreng le masoba a plating.Ntle le moo, PCBS ea koporo e boima e entsoe ka electroplated nakong ea tlhahiso ea PCB.Sena se thusa ho tenya lebota la PTH ho PCB.Litšobotsi tse ling tsa PCBS tse teteaneng tsa koporo tse fapaneng le tse ling tsa PCBS li kenyelletsa:
Boima ba koporo:
Sena ke 'nete hore tšobotsi e ka sehloohong ea PCB e boima ea koporo.E bolela boima ba koporo e sebelisoang ka leoto le leng le le leng ka li-ounces.
Sekoahelo
Koporo ea ka ntle ea koporo.Boima ba koporo ba lera le ka ntle ke moralo o tloaelehileng o behiloeng esale pele.
Lera le ka Hare
Boleng ba koporo le botenya ba dielectric tsa lera le ka hare ke lintho tse tloaelehileng tse boletsoeng esale pele.Leha ho le joalo, li ka fetoloa ho latela litlhoko tse ikhethileng tsa morero.
Kopo ea Koporo e Matla PCB
Li-PCB tse boima tsa koporo li sebelisoa mefuteng e fapaneng ea lisebelisoa, tse kang li-transformer tse bataletseng, ho phatlalatsoa ha mocheso, ho hasana ha matla a phahameng, li-converter tse laolang, joalo-joalo Ho PC, likoloi, sesole le taolo ea mechine, thahasello ea lipoleiti tse nang le koporo e ngata haholo e ntse e eketseha.Liboto tsa potoloho tse hatisitsoeng tsa koporo e boima li boetse li sebelisoa haholo:
1. Phepelo ea matla le converter ea ho laola
2. Bolaoli ba likabo
3. Lisebelisoa kapa lisebelisoa tsa ho cheselletsa
4. Indasteri ea likoloi
5. Baetsi ba lisebelisoa tsa letsatsi, joalo-joalo
